سوال ۳ کنکور ارشد مهندسی کامپیوتر ۱۴۰۳

The blank is coordinated with dated (out of date, no longer current) and the clause leads to the books going out of print. So the missing adjective must reinforce this idea of losing value/relevance over time.

• irrelevant = no longer applicable or important — fits perfectly: books become dated and irrelevant, hence go out of print.
• permanent = lasting forever — contradicts "go out of print."
• fascinating = very interesting — a positive trait, opposite of the intended meaning.
• paramount = supremely important — also positive and contradictory.

Only option 1 keeps the sentence logically consistent.

Exam trick: When a blank is joined by and to a known word (here dated), pick the choice whose connotation matches that word — eliminate any positive-meaning distractors.
