Weaken the Argument Questions | CLAT Logical Reasoning

📑 On this page

⚡ The 20-second answer

A weaken question asks which new fact, taken as true, makes the conclusion less likely. Don't fight the facts; attack the link from evidence to claim: another cause, a broken assumption, a case where the cause shows up without the effect. The #1 trap: an option that strengthens, planted in the line-up.

🎬 The 30-second story

The mushroom-coffee reel

“30 days of mushroom coffee, minus 6 kg. It burns fat! Forwarding!”

📱

Rohan

Rohan's family group, 7 am.

“Bro, it tastes like wet cardboard. Argument destroyed.”

☕

Aarav

Aarav attacks the taste.

“Maybe he never lost 6 kg. Reels lie.”

🎞️

Meher

Meher attacks the given fact.

“Read his caption. Same 30 days: 1,500-calorie diet, 10,000 steps a day.”

🖊️

Zoya

Zoya attacks the link.

Tara's verdict: Taste is out of scope, and “the 6 kg is fake” fights a fact you're handed. Zoya's move is the real weakener: another cause for the same 6 kg. The coffee might still help, but the reel no longer shows it. Weaken the bridge, not the facts.

How does CLAT word weaken questions?

Real CLAT stem	Whose claim?	First move
“…would most weaken the author's arguments?” (2023 Q113, Q130)	The author's main case	Write the conclusion and its reason in one line
“…would most weaken Laura Kray's arguments?” (2023 Q129)	A quoted expert	Find her sentence only; ignore the author
“…weakens the author's idea of ‘having a space where they may be welcomed and listened to, rather than judged’?” (2021 Q110)	One idea, with a value inside	Attack the value
“…would have resulted in the weakening, rather than deepening of public trust in newspapers…?” (2023 Q115)	A cause the author gives	Reverse that cause

What does it actually mean to weaken an argument?

You needn't prove the author wrong; you need the fact that makes a neutral reader trust the conclusion less. One credible crack is enough, and it must be in the reasoning, because the evidence is given as true.

⚔️ Side by side

Attack the link, not the facts

🔨Attack the link

accepts the facts, breaks the reasoning

•“Same month, he went on a strict diet.”

🙅Deny the fact

refuses what the passage gives you

•“He never lost 6 kg.”

Test	Attack the link	Deny the fact
What it targets	The bridge: cause, sample, assumption	A stated premise
Plays by the question's rules?	Yes	No: premises are given
Can it be the answer?	Yes	Almost never

Contradict the reasoning, never a reported number.

📌 The best weakener is often the negated assumption

Name the assumption, flip it, and look for the flipped sentence. 2023 Q130's answer is the negation of “our hunter-gatherer traits still exist”.

Evidence → claim. What must hold for the jump to work?
3
Predict the crack
Another cause? Effect without cause? Skewed sample? Wrong value?

Where do arguments crack?

🔗 Cause check

Four ways to crack a causal claim

Claimed cause

Taking the optional Saturday mock

⟶

causes?

Observed effect

15 marks higher in boards

Before you buy the link, rule these out

🕵️ Third factor (causes both)

Motivated students both sign up and study more

↙ ↘ drives both · weakens the claim

↩️ Reverse cause

Only the top pre-board scorers are invited

good marks lead to the mock, not the other way · weakens the claim

🔀 Another cause

Mock-takers also get one-on-one doubt classes

could produce the effect alone · weakens the claim

🎲 Pure coincidence

Only 12 students took it, one strong batch

too small to trust · weakens the claim

Each card is a ready-made weakener.

Plans (“do X to get Y”): X can't be done, won't deliver Y, or causes a worse harm.
Predictions (“last year, so this year”): conditions have changed.
Comparisons (“A is like B”): a difference that matters.
Opinions and values (2021 Q110): the value the author treats as good isn't.

Which wrong options look like weakeners?

The planted opposite. In 2023 Q129, three options strengthen Kray.
Negative but irrelevant. “It tastes awful” sounds hostile and moves nothing.
Side-detail hit. Attacks a minor point the conclusion doesn't rest on.
Too weak. “A few users…” when another option hits the whole sample.
Repeats the passage. Restating the author's evidence can never weaken it.

Weakening a quoted expert, not the author

A named person shrinks the target to her sentence. In 2023 Q129, Kray explains one finding; the answer attacks that, not the article.

⚠️ “But that contradicts the passage!”

2023 Q108's key says India is “insulated” from the global shocks the author blames. That denies the author's causal claim, not a figure. Data is sacred; explanations are fair game.

Small-town stars of the IPL

A decade ago, IPL squads had a handful of small-town players. Today they have three times as many. The author credits the district cricket academies set up by state associations over the same period. Before them, a talented small-town boy had no turf to train on and no coach to send him for trials. The academies fixed both, so every state should build more.

Which most weakens the author's argument?
(A) The IPL grew from eight to ten teams, adding about a quarter more squad places.
(B) Most small-town IPL players of the last decade were spotted through televised T20 leagues and video trials by franchise scouts, and never attended a district academy.
(C) District academies charge lower fees than city academies.
(D) Small-town players have starred in several IPL finals.

1
Whose claim: the author's: academies caused the tripling.
2
Bridge: the new players came through the academies.
3
Crack: another route produced them.
4
Tag: A small W: a quarter more places can't explain tripling. B big W: another route, effect without the cause. C 0. D 0.
5
Pick: B. Biggest crack wins.

Answer: (B)

Kabir's cold-coffee forecast

Kabir sold an average of 300 cold coffees a day last May, so he stocks for 300 a day this May. Which most weakens his reasoning?
(A) A few regulars say they may cut down on sugar.
(B) The college next door, whose students bought most of last May's coffees, closes for summer from 1 May this year, a month earlier.
(C) Cold coffee has more sugar than hot coffee.
(D) His milk supplier has raised prices by 5%.

1
Whose claim: Kabir's forecast.
2
Bridge: this May's customers will match last May's.
3
Crack: conditions have changed.
4
Tag: A weak W (a few, “may”). B big W: his main buyers vanish all month. C 0. D 0: cost, not demand.

How has CLAT asked weaken questions?

📝 Asked in CLAT 2023 · Q130 Negate the assumption

Why are we humans so susceptible to the doom and gloom of the news? Two reasons. The first is what psychologists call negativity bias: we're more attuned to the bad than the good. Back in our hunting and gathering days, we were better off being frightened of a spider or a snake a hundred times too often than one time too few. Too much fear wouldn't kill you; too little surely would. Second, we're also burdened with an availability bias… In this digital age, the news we're being fed is only getting more extreme… [Rutger Bregman, Humankind]

Which of the following, if true, would most weaken the author's arguments?

ABehavioural traits that helped us in the days when we were hunter-gatherers continue to be present in modern-day humans.

BBehavioural traits that helped us in the days when we were hunter-gatherers are no longer found in modern-day humans.

CThe negativity bias makes us more likely to be affected by depressing or sad news.

DWe have certain behavioural characteristics that affect how we perceive and are affected by sad news.

Reveal answer + reasoning

Answer: B

Bridge: our hunter-gatherer fear reflex still runs in us. B flips it: those traits are gone, so the first reason collapses. Answer B.

📝 Asked in CLAT 2023 · Q129 Weaken a quoted expert

…In an analysis of professors' evaluations, female professors witnessed a decline as they moved from their 30s to 40s, hitting an all-time low around the age of 47. All this while, the evaluation of male professors remained consistent. Interestingly, after the age of 47, the evaluations for women increased again, becoming equal with those of men around the early 60s. “At that point, there are different stereotypes of women, and they may benefit from being seen as more grandmotherly,” said Laura Kray…

Which of the following, if true, would most weaken Laura Kray's arguments?

AWomen professors perceived as being ‘grandmotherly’ are regarded as being likeable and caring.

BWomen professors perceived as being ‘grandmotherly’ are treated better by their colleagues and students.

CWomen professors perceived as being ‘grandmotherly’ are regarded as being slow, inefficient, and outdated in their field.

DWomen professors perceived as being ‘grandmotherly’ are regarded very highly and receive much more respect than younger women professors.

Reveal answer + reasoning

Answer: C

Whose claim: Kray's: ratings rise after 47 because of a “grandmotherly” image. Bridge: that image is favourable. C makes it unfavourable, so it can't explain rising ratings. Answer C.

Why the others fail

A — Likeable and caring is the warmth Kray means. Strengthens.
B — Better treatment fits her explanation. Strengthens.
D — Strongly worded, but in her favour. The planted opposite.

📝 Asked in CLAT 2021 · Q110 Weaken a value

…To date, most people with mental illness remain silent about their condition, avoiding discussing their problems for fear of losing face, damaging their reputation or jeopardising their family status. Having a space where they may be welcomed and listened to, rather than judged, will go a long way towards enabling them to share their experiences…

Which of the following weakens the author's idea of ‘having a space where they may be welcomed and listened to, rather than judged’?

APeople who tend to share their emotions tend to have mental peace and happiness.

BSocietal role is massive in embracing people suffering from mental health ailments.

CPeople sharing their ideas and expressions publicly is a practice which needs to be promoted.

DIt is a human tendency to form judgments about other people and this being a healthy practice should be encouraged at large scale.

Reveal answer + reasoning

Answer: D

Whose claim: one idea with a value inside: not being judged is good. D calls judging healthy and worth encouraging, cutting against “rather than judged”. Answer D.

Why the others fail

A — Sharing brings peace: supports a safe space. Opposite.
B — Society embracing sufferers is the author's point. Opposite.
C — Promoting open sharing supports the idea. Opposite.

A coaching chain in Jaipur reports that students who attended its weekend mindfulness sessions this term scored, on average, 12 percentile points higher in the monthly mocks than students who skipped them. The director concludes that mindfulness improves exam performance. He plans to make the Sunday sessions compulsory for every batch from next term, and to advertise the result in the city's newspapers.

Q1. Which most weakens the director's conclusion?

Over five years, a hill town in the north-east added 40 km of new roads, and tourist arrivals rose by 60%. The state's tourism minister says the new roads brought the tourists in. He announces that the state will now fund similar road projects in six other hill towns, so that tourism there can grow just as quickly as it did here.

Q2. Which most weakens the minister's argument?

Q3. A doctor claims teenagers fall asleep later because screens emit blue light that delays sleep. Which most weakens the claim?

Q4. Students who use a Pomodoro timer app finish mocks 8 minutes faster, so the app trains speed. Which most weakens this?

Q5. An author argues schools should stop publishing rank lists, because public ranks shame low scorers into giving up. Which most weakens the argument?

Weaken questions: the one-page revision

🎯 Weaken questions in a nutshell

Weaken = a fact, taken as true, that makes the conclusion less likely. One crack is enough.
Attack the link, never the reported facts.
Classic cracks: another cause, reverse cause, effect without the cause, a skewed sample, changed conditions, a wrong value.
Strike the planted strengthener first, then let the biggest crack win.

📎 Cheat sheet

“most weaken the author's arguments” → Weaken (main) → conclusion + reason in one line
“weaken [name]'s arguments” → Quoted expert → her sentence only
“weakens the idea of…” → Value claim → attack the value
“weakening, rather than deepening” → Reverse a cause → flip the author's reason
“all of the following weaken EXCEPT” → Reverse filter → the answer is S or 0

Frequently asked questions

How do you answer weaken questions in CLAT?

Find whose claim the stem targets and name the bridge between its evidence and conclusion. Predict how it could crack, such as another cause or a skewed sample. Tag each option weakens, strengthens or no effect, strike the last two kinds, and pick the biggest crack.

Can I weaken an argument by saying a fact in the passage is false?

No. The figures and events reported in the passage are given as true. You weaken the reasoning built on them: the causal claim, the assumption, the sample. An option may contradict the author's explanation, as in 2023 Q108, but not a reported fact.

What is the most common way to weaken an argument in CLAT?

Offering another cause for the same effect, or flipping the assumption the argument rests on. In 2023 Q130 the answer is the negated assumption word for word. In opinion passages, CLAT also weakens by attacking the value the author treats as good, as in 2021 Q110.

Why do weaken questions include options that strengthen?

To catch students who skim the stem. CLAT often fills three of four options with strengtheners or restatements, as in 2023 Q129. Tag every option before choosing and strike anything that supports the author. A strong option in the wrong direction is still wrong.
