سوال ۳ کنکور ارشد علوم کامپیوتر ۱۴۰۲

The fixed collocation "to die in infancy" means to die during the earliest period of life (the first year or first few years). It is the only choice that fits both grammatically and semantically after "dies in": a child can die in infancy (at a very young age).

The distractors fail:

• nutrition = the process of nourishing/food intake — one does not "die in nutrition."
• malfunction = a failure to work correctly (of a machine/organ) — not used for a child's death period.
• mortality = the state of being subject to death, or the death rate; one does not "die in mortality" (you measure mortality, you don't die in it).

So the correct answer is option 1, "infancy."

Exam trick: Look for the established collocation. "Die in infancy" is set; the other nouns may look topic-related (poverty, child death) but break the verb + preposition pattern "die in ___."
