Sentence Completion – MBA CET questions with solutions

Approach: Check each fragment as a consequence of 'With the advancement of EVs'.

Solution: I. EVs run on lithium-ion batteries, so battery demand growing rapidly — logical.
II. More EVs need charging; infrastructure expanding — logical.
III. EVs replace petrol/diesel vehicles, so fossil-fuel use in transport 'gradually' reducing — logical and measured.
All three fit — D.

Why the other options are wrong:
A: Omits valid II and III.
B: Omits valid I and III.
C: Omits valid II.
E: Omits valid I.

Cetking shortcut: Look for absolute words (all, eliminated, no longer) — none here, so all three survive.

Answer: D

Approach: Concession clause — the completion must go against the concern.

Solution: 'Despite concerns about the reliability of AI systems, ___' needs a positive outcome despite doubts.
I. AI diagnostics have improved accuracy — contrasts the concern: fits.
II. Global investment in AI has surged — progress despite doubts: fits.
III. Some AI models still require human supervision — this supports the concern, so 'despite' makes no sense: does not fit.
Answer: I and II — C.

Why the other options are wrong:
A: Leaves out valid II.
B: Leaves out valid I.
D: Includes III, which agrees with the concern.
E: III alone is the one that does not fit.

Cetking shortcut: With 'despite/although', reject any fragment that agrees with the first clause.

Answer: C

Approach: Check each fragment for factual and logical soundness.

Solution: I. Private companies launching commercial satellites — true and a direct result of advancing space technology: fits.
II. Human travel to all planets 'routinely possible' — factually false and exaggerated.
III. Exploration has 'eliminated all uncertainties' about interstellar environments — absolute and false.
Only I — A.

Why the other options are wrong:
B: II is false/exaggerated.
C: III is absolute and false.
D: Both II and III are invalid.
E: III is invalid.

Cetking shortcut: 'All', 'routinely', 'eliminated all' — absolute words knock out II and III instantly.

Answer: A

Approach: Check each fragment for realistic consequence.

Solution: I. Users 'no longer require any local hardware' — false; a device is still needed to access the cloud.
II. Businesses scale without heavy upfront infrastructure costs — the core benefit of cloud: fits.
III. Real-time collaboration across dispersed teams has become seamless — a well-known cloud benefit: fits.
Answer: II and III — D.

Why the other options are wrong:
A: I is an absolute, false claim.
B: Omits valid III.
C: Omits valid II.
E: Includes invalid I.

Cetking shortcut: 'No longer… any' = absolute word → eliminate.

Answer: D

Approach: Contrast clause — 'While' needs an opposing idea.

Solution: 'While interdisciplinary research is increasingly encouraged in academia, ___'.
I. Evaluation systems remain siloed in traditional disciplines — a genuine contrast: fits.
II. Collaboration has 'eliminated the need' for domain expertise — absolute and illogical (interdisciplinary work needs domain experts).
III. Funding has been adapted to support cross-disciplinary projects — supports the first clause; no contrast, so 'while' is misused.
Only I — A.

Why the other options are wrong:
B: III does not contrast with the opening clause.
C: Includes III.
D: II is absolute; III gives no contrast.
E: II and III do not fit.

Cetking shortcut: Read 'while' here as 'although' — keep only the fragment that pushes back.

Answer: A

Approach: The blank must follow 'nature of retirement' and stay on that idea.

Solution: I — 'be it voluntary or after reaching the age of superannuation, among others' lists the kinds of retirement. ✔
II — 'i.e. it should be natural retirement only and not voluntary retirement' specifies the nature of retirement that counts; it attaches grammatically through 'i.e.' and stays on topic. ✔
III — 'the amount of hard work put by others during the career' is about other people's work, which is illogical in a rule on an employee's pension. ✘
So I and II.

Why the other options are wrong:
A, B, D, E — each includes III, which is illogical ('others').

Cetking shortcut: Spot the fragment that drifts off topic (III) — every option containing it is out, leaving only C.

Answer: C

Approach: 'No matter how much…' is a concessive structure: the second half must hold true in spite of the first.

Solution: I — 'No matter how much we mitigate, there prevails some information asymmetry which makes some amount of climate change unavoidable.' However much we mitigate, some change remains — a proper contrast. ✔
II — 'No matter how much we understand him, we will fully grasp…' — illogical; the structure needs 'we will never fully grasp'. ✘
III — 'No matter how much we care for her, it will not be in vain' — the result does not contrast with caring more, so the concession is meaningless. ✘
Only I.

Why the other options are wrong:
B, D, E — include II, which reverses the logic.
C — III is grammatical but gives no concessive contrast.

Cetking shortcut: Test with 'Even if we X a lot, still Y' — only the fragment that makes sense this way is right.

Answer: A

Approach: Both words in the pair must match the positive context ('praised', 'revolutionizing').

Solution: II — 'exceptional and ground-breaking' — both positive. ✔
I — 'absurd' is negative. ✘
III — 'intentional' is neutral and 'heart-breaking' is negative. ✘

Why the other options are wrong:
A, E — include I ('absurd').
C, D — include III ('heart-breaking').

Answer: B

Approach: Join each opening with the ending that completes it grammatically and logically.

Solution: A + E: 'The person behind the fake account disguised himself as hospital staff and did not disclose that he was a consultant.' ✔
B + F: 'It is impossible to sleep with all this commotion going on.' ✔
C + D: 'In spite of the ruckus going on in her family, she managed to study and score good marks.' ✔
All three pairs work: A-E, B-F, C-D.

Why the other options are wrong:
A, C, D, E — each leaves out at least one valid pair.

Answer: B

Approach: Connector fit — meaning and grammar of each fragment before "its implications remaining unclear".

Solution: The second half is an absolute phrase (noun + -ing): "its long-term implications remaining unclear". III. "with" introduces such a phrase to add an accompanying circumstance: "widely debated, with its long-term implications remaining unclear" — correct. I. "despite" creates contrast, but unclear implications are not a reason a proposal would not be debated — illogical. II. "owing to" would turn the phrase into the cause of the debate; the sentence only reports two facts side by side (debated + implications unclear), so a causal link is not supported. Only III fits naturally — option B.

Why the other options are wrong:
A: "despite" gives a false contrast.
C: Both I and II fail.
D: II does not fit.
E: II does not fit.

Cetking shortcut: Pattern "…, ____ + noun + -ing" is the classic slot for "with" (absolute construction).

Answer: B

Approach: Cause connector — the blank must give the reason for failing to scale.

Solution: The startup failed because it had no funding or mentorship. I. "lacking" (participle phrase = since it lacked) works: "failed to scale operations, lacking adequate funding…". III. "because it lacked" states the cause directly. II. "in spite of" means despite having — illogical, since funding would help scaling. I and III — option C.

Why the other options are wrong:
A: Misses III, which also fits.
B: Misses I, which also fits.
D: II is illogical.
E: II is illogical.

Cetking shortcut: Decide the relation first (cause vs contrast); then keep every fragment that expresses cause.

Answer: C

Approach: Fragment fit — the structure "has been ___ X and Y becoming major concerns".

Solution: The sentence describes developments that came along with social media's growth. I. "accompanied by": "has been accompanied by misinformation and declining public trust becoming major concerns" — growth occurring alongside these problems; fits. III. "marked by": the expansion has been characterized by these concerns; fits in meaning and grammar. II. "responsible for" asserts direct causation — that social media alone caused misinformation and declining trust — a sweeping claim the neutral sentence does not support, so it is rejected. I and III — option C.

Why the other options are wrong:
A: Misses III, which also fits.
B: Misses I, which also fits.
D: II overstates causation.
E: II overstates causation.

Cetking shortcut: "Accompanied by" and "marked by" both describe what came with something — if one fits, test the other the same way.

Answer: C

Approach: Choose the idiomatic phrase for steady growth over time.

Solution: 'Increases' describes a continuing, gradual rise. The idiom 'year by year' means gradually, with each passing year, and fits naturally: 'the talent is prodigious, and it increases year by year.'

Why the other options are wrong:
A: 'each year' – states frequency only, not the steady, gradual build-up that 'year by year' conveys.
B: 'progressively' – grammatical but vague; does not convey the yearly growth.
C: 'annually' – means 'once a year' (an annual event), not continuous growth.
E: 'yearwise' – not standard usage.

Cetking shortcut: 'X by X' idioms (day by day, year by year) express gradual change – they pair naturally with 'increases'.

Answer: D
