1. (e) 1- We need to replace REGRESS (return to a former or less developed state) with PROGRESS (development towards an improved condition). REGRESS is a verb and PROGRESS is a noun. 2- We need to replace SURMOUNTING (overcome (a difficulty or obstacle)) with MOUNTING (grow larger or more numerous). We need an adjective to modify the noun CRISES. 3- We need to replace AFFECTS with EFFECTS. We need a noun here as denoted by the use of the article THE (articles are used to modify only nouns). AFFECT is a verb, and it means to impact or change. EFFECT is a noun, an effect is the result of a change. Since BBB is the correct combination, (e) is the right answer.
