سوال ۱ کنکور ارشد مدیریت ۱۴۰۵
Remember that Instagram is not a good ………….…… of medical and health-related information.
پاسخ صحیح: گزینهٔ B — source
The blank needs a noun that fits the collocation “a good ___ of information” — the thing information comes from. Only one of the four nouns takes of information in that sense.
Meaning of all four options
| Option | Meaning | Persian gloss |
|---|---|---|
| 1) discovery | the act of finding something not known before | کشف، اکتشاف |
| 2) source | the place or thing that something (esp. information) comes from | منبع، سرچشمه |
| 3) cause | the thing that makes something happen | علت، سبب |
| 4) agreement | shared opinion, or a formal arrangement | توافق، موافقتنامه |
Why (2) source. Source of information is a fixed, high-frequency collocation: a reliable source of information, a good source of news. The sentence warns that Instagram should not be trusted as a place to get medical information from — exactly what source expresses.
Why the others fail
- discovery — you make a discovery, but nobody is a discovery of information; it names an event, not a provider, so it cannot follow a good … of information.
- cause — a cause of X means X is a result (a cause of stress). Instagram does not produce medical information as an effect; the sentence is about where you get it, not what triggers it.
- agreement — an agreement on/about a subject means consensus or a contract; it has nothing to do with supplying information.
Exam trick: In single-word completion items, read the preposition after the blank first. … of information instantly narrows the field to nouns that take that complement (source, piece, body), and three distractors die before you even weigh their meanings.
