Why RC and Critical Reasoning matter in GATE GA
Among the 15 GA marks in every GATE paper, Reading Comprehension and Critical Reasoning are the highest-value verbal questions. They are usually 2-mark questions, which means a wrong answer costs you 2/3 of a mark and a correct one gives you as much as two grammar questions. Since GATE 2021, almost every paper has included a short passage of 80 to 150 words followed by one or two questions, plus one standalone reasoning question of the “which statement can be inferred” or “which option weakens the argument” type.
The passages are short and the language is simple. The difficulty is in the options. GATE writes three distractors that are each true in the real world, reasonable, or almost said in the passage. Only one option is strictly supported by the text. This guide teaches you to find that one. Scores like 15/15 in GA are common among students who treat RC as a precision task, not a reading task. For the full picture of GA weightage and strategy, see the GATE General Aptitude 2027 hub.
| Year | Marks from RC and reasoning (approximate, across papers) | Typical question type |
|---|---|---|
| 2019 | 2 | Short passage, inference |
| 2020 | 2 to 3 | Passage inference, statement reasoning |
| 2021 | 2 to 4 | Passage, “which can be concluded” |
| 2022 | 2 to 4 | Passage, assumption |
| 2023 | 2 to 4 | Passage, main idea, weaken |
| 2024 | 2 to 4 | Passage inference, conditional reasoning |
| 2025 | 2 to 4 | Passage, author’s view |
| 2026 | 2 to 4 | Passage inference, strengthen |
What the official GA syllabus says
Critical reasoning sits between these two lines. A passage question tests comprehension; a “which statement follows” question tests deduction. In practice GATE blends them, so this guide covers both together. Pure syllogisms and statement-conclusion questions have their own guide later in this series.
The 90-second reading method
A GATE passage is 80 to 150 words. You can read it twice in 90 seconds. Here is how to spend that time.
- Read the question stem first (10 seconds). Know whether you are looking for the main idea, a specific fact, an inference, or the author’s attitude. This decides how you read.
- Read the passage once at normal speed (40 seconds). Mark, mentally or on the rough sheet, every qualifier: only, all, some, most, never, always, unless, except, not necessarily, may, must. These words decide 80 percent of RC answers.
- Identify the author’s claim and the evidence (10 seconds). Most GATE passages have one claim, one or two pieces of support, and often a contrast (“however”, “but”). The claim is usually in the first or last sentence.
- Attack the options with the passage, not with your knowledge (30 seconds). For each option ask: “Which sentence in the passage supports this?” If you cannot point to one, the option is wrong, even if it is true in real life.
Which of the following can be inferred?
(A) Solar pumps have eliminated diesel use in the district.
(B) Farmers with deep aquifers prefer diesel pumps.
(C) The benefit of solar pumps in the district depends on groundwater depth.
(D) Diesel pumps are more powerful than solar pumps everywhere.
Solution: (A) says “eliminated” but the passage says “reduced” and “only where”. (B) says “prefer”; the passage says they “continue to depend”, which is necessity, not preference. (D) generalises “everywhere”; the passage only compares them in deep-aquifer areas. (C) restates the passage’s central contrast. Answer: (C)
Inference questions: the four rules
“Which of the following can be inferred / concluded / is implied” is the most frequent RC stem in GATE. Apply these four rules in order.
Rule 1: Stay inside the passage
An inference is something that must be true if the passage is true. It is not something that is probably true in the world. If the passage says “most engineers in the survey preferred remote work”, you cannot infer “most engineers prefer remote work” (the survey is not the world) or “remote work is more productive” (the passage says nothing about productivity).
Rule 2: Respect the quantifier
“Some” does not mean “most”. “Most” does not mean “all”. “Many” is not a number. “Not all” means at least one is not. “Only X are Y” means every Y is an X, not that every X is a Y. GATE options routinely upgrade “some” to “all” or flip “only”.
Rule 3: Respect the direction of a conditional
“If the soil is sandy, drainage is fast” lets you conclude: not fast drainage means not sandy (contrapositive). It does not let you conclude: fast drainage means sandy (converse) or not sandy means not fast (inverse). Keep this table in your head.
| Given: If P then Q | Statement | Valid? |
|---|---|---|
| Contrapositive | If not Q then not P | Yes, always |
| Converse | If Q then P | No |
| Inverse | If not P then not Q | No |
| “P only if Q” | Same as: If P then Q | Yes |
| “P unless Q” | Same as: If not Q then P | Yes |
Rule 4: Distinguish fact, claim and opinion
“The author believes” questions are about what the writer thinks, not what is true. If the passage reports that “critics argue X”, you cannot infer that the author agrees with X. Look for the author’s own voice: “clearly”, “unfortunately”, “it is evident that” signal opinion; “the study found” signals reported fact.
(A) Every model that passes the fairness audit is deployed.
(B) Model Q passed the fairness audit.
(C) Model Q is the only model deployed last week.
(D) Models that fail the audit are retrained.
Solution: “Deployed only if passes” means: if deployed, then passed. Q was deployed, so Q passed. (A) is the converse and invalid. (C) and (D) add information not given. Answer: (B)
Critical reasoning: assumptions, strengthen, weaken, conclude
A critical reasoning question gives you a short argument (two to four sentences) and asks one of four things. Each has a precise method.
Assumption: the unstated link
An assumption is something the argument needs to be true but does not say. Test: negate the option. If negating it destroys the argument, it is the assumption. Argument: “Our app’s downloads doubled after the ad campaign, so the campaign was effective.” Assumption: nothing else (a festival, a competitor’s outage) caused the rise. Negate it: “something else caused the rise”, and the argument collapses.
Strengthen and weaken: attack the link, not the facts
To weaken, find an option that offers an alternative explanation, breaks the cause-effect link, or shows the sample is unrepresentative. To strengthen, find an option that rules out an alternative or adds support for the link. Do not pick options that merely repeat the conclusion or that attack an unrelated fact.
Conclusion: the smallest safe step
The right conclusion is the one that combines the given statements without adding anything. If statements say “All trained operators passed; Ravi did not pass”, the conclusion is “Ravi was not trained” (contrapositive). It is not “Ravi will fail again” or “training guarantees success in all cases”.
(A) Congestion pricing is unpopular with shopkeepers in central areas.
(B) The same cities also opened new metro lines in the same year.
(C) Traffic in the suburbs of these cities increased slightly.
(D) The 15 percent figure was measured by an independent agency.
Solution: The argument assumes pricing caused the drop. (B) gives an alternative cause for the drop, which directly attacks that link. (A) is irrelevant to effectiveness. (C) does not deny that central traffic fell. (D) strengthens the data. Answer: (B)
A full worked passage
This passage is written for this guide in GATE’s style and length. Read it with the 90-second method, then check the three questions that follow.
Small irrigation tanks were once the backbone of farming in the semi-arid districts of the Deccan. Each tank stored monsoon runoff and released it through sluices during the dry months, and village committees maintained the bunds and desilted the beds every few years. After the 1970s, as borewells spread, many farmers stopped depending on the tanks, and the committees gradually dissolved. Today, most tanks are silted and their catchments encroached. Some state programmes have tried to revive them by paying contractors to desilt, but these efforts rarely last, because without a committee that benefits from the tank, nobody maintains it after the contractor leaves. The evidence suggests that the physical repair of a tank is the easier part; rebuilding the institution around it is the harder part, and the part that decides whether the repair survives.
(A) The state government took over tank maintenance.
(B) Farmers shifted to borewells and no longer depended on the tanks.
(C) Contractors replaced the committees.
(D) The tanks silted up and became unusable.
Solution: The passage links the dissolution directly to borewells: “as borewells spread, many farmers stopped depending on the tanks, and the committees gradually dissolved.” Silting (D) is described as a present-day consequence, not the cause. (A) and (C) are not stated. Answer: (B)
(A) Borewells should be banned in semi-arid districts.
(B) Desilting contracts are a waste of public money.
(C) Tank revival depends more on rebuilding local institutions than on physical repair.
(D) Village committees were more efficient than state programmes.
Solution: The last sentence states the thesis: repair is easier, rebuilding the institution is harder and decisive. (A) is never suggested. (B) overstates “rarely last” into “waste”. (D) compares efficiency, which the passage does not do. Answer: (C)
(A) All irrigation tanks in the Deccan are now silted.
(B) A revived tank is more likely to stay functional if a local group benefits from it and maintains it.
(C) Borewells have lowered the water table across the Deccan.
(D) State programmes have never succeeded in desilting a tank.
Solution: (A) upgrades “most” to “all”. (C) is plausible in reality but absent from the passage. (D) upgrades “rarely last” to “never succeeded” and confuses desilting with lasting. (B) follows from “without a committee that benefits from the tank, nobody maintains it”. Answer: (B)
Shortcuts and traps
❌ Upgrading “some” to “most” or “most” to “all” while reading.
❌ Treating the converse of a conditional as valid (“if deployed then passed” read as “if passed then deployed”).
❌ Choosing an option because it is true in real life rather than supported by the text.
❌ Attributing a reported view (“critics say”) to the author.
❌ Weakening an argument by attacking an irrelevant detail rather than the cause-effect link.
❌ Reading the passage three times and the options once; it should be the other way round.
Solved previous-year and GATE-style questions
The following eight questions follow the exact formats seen in GATE 2021 to 2026 across streams. The arguments and passages are written fresh, so they are labelled GATE-style. Original PYQs with full solutions are in the PiyushAI GATE Aptitude Test Series.
(A) Priya attended the workshop.
(B) Priya may or may not have attended the workshop.
(C) Only workshop attendees received certificates.
(D) Priya did not attend the workshop.
Solution: Attending guarantees a certificate, but the statement does not say certificates were given only to attendees. Having a certificate does not prove attendance (converse error). So Priya may or may not have attended. Answer: (B)
(A) The plant manager does not believe the audit.
(B) A low-cost measure to cut energy use is being delayed for reasons unrelated to its cost.
(C) Compressed-air leaks are the largest source of energy loss in all factories.
(D) Production deadlines cannot be met if the leaks are fixed.
Solution: (A) is not stated; the manager cites deadlines, not disbelief. (C) generalises to all factories. (D) overstates “citing deadlines” into impossibility. (B) matches: cheap fix, postponed, reason is deadlines. Answer: (B)
(A) Employees enjoy taking leave.
(B) Taking leave causes lower stress, rather than less stressed employees being more likely to take leave.
(C) One week is the ideal duration of leave.
(D) All companies currently allow at least one week of leave.
Solution: The argument moves from a correlation to a policy that assumes causation in one direction. Negate (B): if less stressed people simply take more leave, forcing leave would not reduce stress, and the argument fails. (A), (C) and (D) are not required. Answer: (B)
(A) If the repair is completed by Saturday evening, the bridge will not be closed on Sunday.
(B) If the repair is not completed by Saturday evening, the bridge will be closed on Sunday.
(C) The bridge will be closed on Sunday only if the repair is completed.
(D) If the bridge is open on Sunday, the repair was not completed.
Solution: “P unless Q” means “if not Q then P”. Here P = closed on Sunday, Q = repair completed by Saturday. So: if not completed, then closed. (A) is the inverse and not guaranteed by “unless” alone in strict logic. (C) reverses the condition. (D) contradicts the statement. Answer: (B)
(A) Rural buyers prefer petrol scooters because they are cheaper.
(B) Electric two-wheelers will soon outsell petrol scooters in rural districts.
(C) Price is unlikely to be the main barrier to electric two-wheeler adoption in rural districts.
(D) Charging points are unavailable in all rural districts.
Solution: (A) contradicts the passage (electric models are cheaper). (B) is a prediction the passage does not make. (D) upgrades “absence” as a reason to “all districts”. (C) is supported by the dealers’ reasoning and the price comparison. Answer: (C)
(A) The survey was conducted during peak hours when trains are crowded.
(B) The survey used a printed questionnaire.
(C) Seat prices on long-distance trains have risen recently.
(D) Some commuters refused to answer the survey.
Solution: The conclusion generalises from one station at one time to the whole city. (A) shows the sample is biased toward people who are standing in crowded trains and therefore unusually willing to pay. (B) and (C) are irrelevant. (D) is weak without knowing how many or who refused. Answer: (A)
(A) All components that were shipped passed the vibration test.
(B) All components that passed the vibration test were shipped.
(C) Some components that failed the vibration test were rejected for cosmetic defects.
(D) Components with cosmetic defects failed the vibration test.
Solution: From “no failed component was shipped”, every shipped component must have passed: (A) is valid. (B) is contradicted by the second statement. (C) and (D) connect groups the statements never connect. Answer: (A)
(A) online examinations cannot prevent cheating.
(B) cheating depends more on how a test is designed than on whether it is online.
(C) closed-book tests should be abolished.
(D) critics of online examinations are dishonest.
Solution: “However” marks the author’s own position: the problem is design, not medium. (A) is the critics’ view. (C) and (D) are not stated. Answer: (B)

Questions 1 to 3 refer to this passage, written for this guide.
Hostel wardens at a technical institute noticed that complaints about internet speed peaked between 9 pm and midnight, when most students were streaming video. The institute doubled its bandwidth, but complaints fell by only a small margin. A later check showed that the hostel’s internal Wi-Fi routers, not the external link, were saturated during those hours. The wardens concluded that in future, measurements should precede purchases.
- Why did doubling the bandwidth have little effect on complaints? (A) Students streamed even more video. (B) The bottleneck was in the internal routers, not the external link. (C) The complaints were about something other than speed. (D) The bandwidth was not actually doubled.
- Which of the following can be inferred? (A) The institute wasted all the money spent on bandwidth. (B) Complaints stopped entirely after the routers were replaced. (C) The institute acted on an assumption about the cause before verifying it. (D) Students should be banned from streaming at night.
- The wardens’ conclusion, “measurements should precede purchases”, is best described as (A) a statement of fact from the passage. (B) a lesson drawn from the experience. (C) a criticism of the students. (D) a prediction about future complaints.
- “Every file that is encrypted is backed up. File X is not backed up.” Which must be true? (A) File X is encrypted. (B) File X is not encrypted. (C) File X will be encrypted later. (D) Nothing can be concluded.
- “Our website’s bounce rate fell after we changed the font. Therefore, the new font keeps visitors on the site longer.” Which option most strengthens this? (A) The font is popular among designers. (B) No other change was made to the website during that period. (C) The bounce rate is measured by a third-party tool. (D) Competing websites use a different font.
Show answer key
- (B) The check showed the internal routers were saturated, so the external bandwidth was not the constraint.
- (C) They bought bandwidth before measuring; (A) says “all” and “wasted”, which overstates; (B) and (D) are not in the passage.
- (B) The sentence generalises from what happened into a rule for the future, which is a lesson, not a fact or prediction.
- (B) Contrapositive: if not backed up, then not encrypted.
- (B) Ruling out other changes removes alternative causes and supports the font as the cause.
One-page rule sheet
Mark qualifiers: only, all, some, most, never, always, unless, except, may, must, not necessarily.
Inference test: “Which sentence supports this?” No sentence means wrong option.
Quantifiers: some is not most; most is not all; “only X are Y” means every Y is an X.
If P then Q: contrapositive (not Q so not P) valid; converse (Q so P) and inverse (not P so not Q) invalid.
P only if Q = if P then Q. P unless Q = if not Q then P.
Assumption: negate the option; if the argument collapses, that is the assumption.
Weaken: alternative cause, broken link, biased sample. Strengthen: rule out alternatives, confirm the link.
Conclusion: smallest step that combines the statements with nothing added.
Author’s view: look after “however”, “but”, “in fact”; reported views (“critics argue”) are not the author’s.
Extreme words in options (always, never, all, proves, eliminates) are suspect unless the passage used them.
Time budget: 90 seconds per passage, 60 seconds per reasoning question.
Common mistakes
❌ Picking the option that “sounds like” the passage without checking the quantifier.
❌ Accepting the converse of a conditional.
❌ Confusing “the author believes” with “the passage mentions”.
❌ Weakening an argument by disputing a number instead of the causal link.
❌ Choosing a conclusion that goes one step further than the statements allow.
❌ Spending three minutes on a passage because it is “interesting”.
FAQs
How long are the passages in GATE General Aptitude?
Short. Most are 80 to 150 words, followed by one or two questions. GATE does not set the 500-word passages seen in CAT or GRE, so speed reading is unnecessary; precision is what matters.
Are RC questions 1 mark or 2 marks?
Usually 2 marks, which is why they matter. A passage with one 2-mark question appears in nearly every paper since 2021, and a standalone critical reasoning question (1 or 2 marks) appears in most.
Do I need to practise with CAT material?
No. CAT passages are longer and test different skills. Practise with GATE PYQs from all streams (the GA section is common), which gives you 60 to 80 passages from 2010 onward, plus the topic-wise RC tests in the PiyushAI series.
Is the PiyushAI Aptitude Test Series enough for GA?
Yes. The Best GATE Aptitude Test Series 2027 has dedicated reading comprehension and critical reasoning tests, every GA PYQ from 2010 to 2026 with explanations, full-length GA mocks in the GATE interface and All-India ranking. Combined with the free guides in this series, it covers the entire GA syllabus.
What is the single most useful habit for RC?
Pointing. For every option, physically or mentally point to the sentence in the passage that supports it. If you cannot point, you cannot pick. This one habit removes the outside-knowledge errors that cause most RC losses.
Stop losing easy marks. Practise this topic under exam pressure.
