Inference Questions in Logical Reasoning

⚡ The 20-second answer

An inference is a claim the passage never states but forces: one small step, no outside knowledge. Method: pin the line, take one step, ask if the passage is true, must this be true? The #1 trap: the option that sounds wise but needs facts the passage never gave.

🎬 The 30-second story

The 2 a.m. group exit

“Meher left the ‘CLAT Warriors’ group at 2:07 a.m.! Screenshot attached.”

📱

Rohan

Rohan, archivist of chaos.

“Obvious. She's quit CLAT. Probably switching to NEET.”

🛌

Aarav

Aarav needs one data point.

“Her phone was in use at 2:07, and she's not in the group now. The rest is a story.”

🖊️

Zoya

Zoya's red pen.

“I left every group. 40 mocks to go. Why is everyone calling?”

📚

Meher

Next morning.

Tara's verdict: Zoya's two lines are inferences: if the screenshot is genuine, they must be true. Aarav's ‘she quit CLAT’ needs facts nobody had.

How does CLAT word inference questions?

Stem (real papers)	What it really asks
“Which of the following can be inferred?” (2020 Q120, Q134)	One step beyond the lines, which the lines support
“Which can be deduced?” (2021 Q117)	Same task, stricter: it must follow
“Which cannot be inferred?” (2020 Q132; 2021 Q121)	Three are supported; find the one that isn't
“What can be most conveniently inferred?” (2022 Q113)	The best-supported of several options
“The paragraph best supports” (2018 Q122)	The two-line version of the same test

No stem asks what you think, what is likely in real life, or what anyone should do. The passage is the whole universe. Since 2020 it is a 400-word editorial, so finding the right line is the hard part.

What exactly is an inference, and what isn't?

🎚️ The scale

The inference ladder

← Says itMakes it up →

Stated

Said in other words.

e.g. Passage: “Since the metro opened, ridership on the 7 a.m. bus has halved.”

Safe inference

Unwritten, but can't be false.

e.g. “The 7 a.m. bus carried more people before the metro opened.”

Stretch

Plausible, not forced.

e.g. “The metro caused the fall.”

Wild guess

Needs facts that appear nowhere.

e.g. “The route will be shut next year.”

CLAT's answer lives on rung two, sometimes rung one. The test: could the passage be true and the option still be false? Fares might have risen that month, so ‘the metro caused it’ is a stretch.

⚔️ Side by side

Inference vs assumption

➡️Inference

What the passage leads to

•Comes after the premises
•Test: if the passage is true, must this be?

🌉Assumption

What the argument stands on

•Comes before the conclusion, unsaid
•Test: negate it; does the argument collapse?

Test	Inference	Assumption
Stem words	inferred, deduced, best supports	assumes, presupposes, implicit

📌 The pointing test

Before picking an inference, point to the line (or two lines) that forces it. No line, no inference, however true it is in the newspaper.

How do you solve an inference question in 40 seconds?

1
Polarity
Circle ‘can’ or ‘cannot’. In ‘cannot be inferred’ you hunt the one unsupported option.
2
Pin the line
Find the sentence (or pair) each option is about. No line? Strike it.
3
Take one step
Ask: if these lines are true, must this be true? A new cause, a prediction or a ‘should’ is too far.
4
Trap-check
Check survivors for an inflated word (some → all, may → will). Pick the most modest one.

Which wrong options look like inferences?

🧩 At a glance

The six impostors

📢Too strong

Passage says many or may; option says all or will.

🔮The prediction

Passage describes now; option announces the future.

🧠Outside knowledge

True in real life, absent from the page.

↩️The cause leap

Two things happen together; option says one caused the other.

🗣️Wrong speaker

A view the author reports, passed off as the author's own.

📜The ‘should’

A diagnosis turned into a cure the author never wrote.

⚠️ Diagnosis is not prescription

An author who says a system suppresses growth has diagnosed a problem. An option saying it should be abolished is a prescription. Unless the passage argues for the cure, it's a stretch.

The library that didn't get busier

Every library in the district that opened a children's reading room saw weekday footfall rise. The Ashok Nagar library, in the same district, saw no rise. Which can be inferred?
(A) Ashok Nagar opened no children's reading room. (B) Children's rooms are the main driver of footfall. (C) Ashok Nagar is badly run. (D) Its weekend footfall fell.

1
Line 1 is a rule: reading room → weekday rise. Line 2: no rise at Ashok Nagar.
2
So it can't have opened a room. B ranks causes never ranked; C is outside knowledge; D is about weekends, never mentioned.

Answer: (A)

The cycle-lane victory lap

In 2024 the city added 40 km of cycle lanes, and bike-share trips rose from 2 lakh to 3 lakh. Officials credit the lanes. But that year petrol prices jumped and the metro shut for five months. Which can be inferred?
(A) The lanes caused the rise. (B) The passage gives reasons to doubt the lanes alone explain it. (C) Trips will keep rising in 2025. (D) The officials are wrong.

1
Pin: the officials' claim, then a ‘But’ adding two other events that year.
2
A repeats the officials' view as fact: a cause leap. C is a prediction.
3
D goes too far: other possible causes don't prove the lanes did nothing. B is exactly what the ‘But’ does.

Answer: (B)

⚡ The exam-hall shortcut

A ‘But’ after someone's claim means ‘this isn't settled’, never ‘this is false’.

✍️ Worked example Tricky ⏱ 60 sec

The phone-ban editorial

When a state banned mobile phones in its schools last year, the move was cheered as a blow against distraction. Teachers in 300 schools reported fewer interruptions. But the ban has a quieter side. Many rural students had been watching recorded lectures on the long bus ride home, because their villages have no coaching centres and no reliable power after dark. Since phones cannot now be brought to school at all, those lectures are gone. For them the phone was not a distraction from study; it was the study. None of this means the ban is wrong. It means one rule cannot fit every student equally.
Which can be inferred?
(A) The ban has failed to reduce classroom distraction. (B) For some rural students, the ban removed a study resource they relied on. (C) City students don't study on their phones. (D) The government should withdraw the ban.

1
Map: praise, then ‘But’ (rural students lose bus-ride lectures), then the verdict (‘the ban isn't wrong’).
2
A and D are opposite: interruptions fell, and the author defends the ban.
3
C is outside the passage: city students are never described.
4
B joins two lines, and ‘some’ matches ‘many rural students’.

Answer: (B)

⚡ The exam-hall shortcut

‘Praise, But, measured verdict’ editorials key the measured middle. Strike the options that pick a side harder than the author.

How has CLAT asked inference questions?

📝 Asked in CLAT 2020 · Q120 Diagnosis vs prescription

…The Class XII CBSE pass result has soared to an all-time high of 88.8%. … The goal of reducing student stress levels during this turbulent time is excellent and laudable. But it is a fallacy that high marks can accomplish this by themselves. The real stressor, after all, is shortage of opportunities. When every bout of grade inflation raises cut-offs for higher education even higher, it is no succour. … Licence raj continues to suppress autonomy and expansion in this sector. … It is better prospects alone that will best alleviate students' stress.

Which of the following can be inferred from the passage above?

AScoring High marks in XII class can help in reducing stress amongst students in the times of Pandemic.

BHigh Cut-off of marks also contribute in reducing opportunities for the students.

CPrivate institutions should not be regulated.

DLicense Raj should be done away with.

Reveal answer + reasoning

Answer: B

Join two lines: the real stressor is ‘shortage of opportunities’, and inflation that ‘raises cut-offs… is no succour’. Higher cut-offs shut more students out. That is the author's own chain, one step on. Answer B.

Why the others fail

A — Opposite: the author calls this ‘a fallacy’.
C — Too strong: objecting to licence raj isn't rejecting all regulation.
D — The closest trap. The author criticises licence raj (diagnosis) but never says scrap it (prescription).

📝 Asked in CLAT 2020 · Q134 Two voices, one inference

…One of the teachers felt students are actually more responsive and active in online classrooms, compared to when they are in physical ones. … Shweta Kawatra, a parent who teaches in a New Delhi school, highlights that many students have not been able to take advantage of the virtual platform because they do not have a suitable device at home or lack a good internet connection. “It has its own share of disadvantages too. Too much screen time can be perilous for health…,” Kawatra adds.

Which of the following can be inferred from the passage above?

AThere is a divide in opinions of people on the merits and demerits of Online education.

BOnline education system is going to replace the Institutionalized education system.

CThe institutionalized education system is not at all perilous for health of students.

📝 Asked in CLAT 2021 · Q115 When the strong option is right

One of the most important challenges for Indian diplomacy in the subcontinent is to persuade its neighbours that India is an opportunity, not a threat. … If India has to fulfil its potential in the world, we have no choice but to live in peace with our neighbours, in mutual security, harmony and cooperation.

Which of the following can be inferred from the above passage?

AThere is no nexus between cooperative existence and economic growth of a nation.

BUnless India's region becomes more self-centred, India is unlikely to develop into more than a regional power.

CIndia can only become a great power if it works in isolation to achieve the desired goals.

DIndia cannot aspire to be a great power without the cooperation of neighbours.

Reveal answer + reasoning

Answer: D

‘We have no choice but to live in… cooperation’ makes cooperation a requirement for India fulfilling its potential. ‘Cannot… without cooperation’ is the same claim. Answer D: a strong option that wins because the passage is just as strong.

Why the others fail

A — Opposite: the passage ties cooperation to wider gains.
B — Opposite: ‘self-centred’ reverses the cooperation the author calls essential.
C — Opposite: isolation contradicts ‘no choice but… cooperation’.

Q1. Which can be inferred?

Kabir's café started a ₹20 ‘refill your own bottle’ offer in June. Over June and July, packaged water sales fell by 60 per cent compared with April and May, while the number of customers stayed roughly the same. The bin outside, which used to overflow by evening, now has room to spare. Kabir has changed no other prices. Several regulars now carry their own steel bottles.

Q2. Which can be inferred?

Since the library began opening until midnight in exam weeks, late-night users rose from about 50 to 400. Students have petitioned the canteen, which shuts at 9 p.m., to stay open. Most late-night users are first-years.

Q3. Which CANNOT be inferred?

Many private schools in the city raised fees by over 15 per cent this year. Some parents have moved their children to government schools.

Q4. Which can be inferred?

In a six-month trial, 30 companies moved staff to a four-day week with no pay cut. Twenty-five kept it afterwards. Managers at most of these firms said output was unchanged, and staff reported much less burnout. The other five went back to five days, citing trouble covering customer calls. No firm cut staff numbers or changed its prices during the trial.

Q5. Which can most reasonably be inferred?

🎯 Inference in a nutshell

An inference is unwritten but forced by the passage.
No line to point at, no inference.
The best options often join two sentences.
Strike the six impostors.
Strong words are fine when the passage is just as strong.

📎 Cheat sheet

“Can be inferred / deduced” → inference → pin the line, take one step
“Cannot be inferred” → mark S or ✗; the lone ✗ wins
“Most reasonably inferred” → pick the most modest survivor
“According to the passage” → stated fact → match the line word for word
“The author assumes” → assumption → negate it; does the argument collapse?
“All of the above” → test each alone; one failure sinks it

Frequently asked questions

What is an inference in CLAT Logical Reasoning?

A statement the passage does not make in words but clearly forces or strongly supports. It is one small step from the text, needs no outside knowledge, and cannot be false if the passage is true. CLAT asks for it as ‘can be inferred’, ‘can be deduced’ or ‘best supports’.

What is the difference between an inference and an assumption?

An inference follows from what is written, whether or not the author needed it. An assumption is an unstated premise the argument depends on. Test an inference by asking whether it must be true if the passage is true; test an assumption by negating it and seeing whether the argument collapses.

Is a restatement of the passage a valid inference answer?

Often, yes. An option that says what the passage says in other words is certainly supported, and CLAT keys often reward options close to the text. Don't reject them as too obvious; just check the paraphrase hasn't swapped a strength word, such as some for all.

Can I use general knowledge in inference questions?

No. The passage is the whole universe for that question. An option can be true in real life and still be wrong because nothing in the passage supports it. If you cannot point to the sentence or pair of sentences that forces it, strike it.
