Q. (2)

Accepted Answer

1) Syntactic fit: The fragment reads "the roads, buildings, power lines and telephone networks that we ___ on daily." This requires a verb that combines with the preposition "on" to take "that" (the networks) as its object. "Rely" forms the natural phrasal verb "rely on," so "that we rely on daily" is a grammatically complete relative clause.

2) Morphological/tense fit: The simple present "rely" after "we" correctly expresses habitual action or general truth (people habitually depend on infrastructure every day). "Rely" therefore matches the required verb form and aspect.

3) Semantic fit: "Rely" means to depend upon or place trust in something for regular functioning. That meaning directly matches the context — infrastructure items are essential systems people depend on in daily life.

4) Idiomaticity and fluency: "Rely on daily" is a common, natural collocation in English; the clause reads smoothly and succinctly, preserving the intended meaning and tone of the passage.

Taken together — grammatical structure, tense, meaning and idiomatic usage — justify the choice of "rely" for the blank. FINAL_ANSWER: B
