سوال ۳ کنکور ارشد مهندسی مکانیک ۱۴۰۳

Option 1: irrelevant. Dated means outdated or no longer suited to current tastes; irrelevant means no longer connected with or important to the matter at hand. The sentence traces a decline: today's best-sellers lose their contemporary relevance and eventually stop being printed.

• 2) permanent means lasting indefinitely. It does not express the loss of relevance suggested by “dated” and “go out of print.”
• 3) fascinating means extremely interesting. Nothing in the sentence suggests that becoming outdated makes these books more interesting.
• 4) paramount means more important than anything else, or of supreme importance. This conflicts with the decline in relevance described here.

Thus “become dated and irrelevant” is the coherent pairing.

Exam trick: Read beyond the blank: go out of print confirms the negative direction already signaled by dated.
