IPMAT Indore 2025 · Verbal Ability · Question 18

Work blank by blank.

Blank 1 — describes a period of time. The standard collocation is extended period. (Extensive describes range or area, not duration; expanded implies something was made bigger; explicit means clearly stated and makes no sense with “period”.)

Blank 2 — pairs with endurance, and is contrasted with mental in the third slot. The natural opposite pairing is physical endurance vs mental something. ✓

Blank 3 — mental resilience = the capacity to recover from difficulty. Perfect for astronauts enduring long missions.

Why the others fail:

Option 1 — dysfunctional endurance is self-contradictory, and the sentence is praising them (“remarkable”).

Option 2 — stoic endurance is idiomatic, but explicit period is not English, and mental integrity is not a standard phrase.

Option 3 — stern describes manner, not endurance; mental acuity is real but means sharpness, which is less apt than resilience for enduring a long stay.

Only option 4 is natural in all three slots.

Answer: Option 4 — extended; physical; resilience
