'Grappled' and 'inveigled' away all the problems does not make sense, as Mary sorted out the problems. Hence, (2) and (3) can be ruled out. “Conjured” gives more sense to the blank instead of “resolved” as it means to cause or effect as if by magic. The stress placed on Mary in this sentence confirms this. 'Spurned' means to refuse, which is off the track. Hence, (1) is the answer.

As fascism and communism are contrary to democracy, therefore “antithesis” replaces the blank. Hence, (4) is the answer.

Dreadful is something terrible, appalling, fearful. In nature, dreadful limits would be set to the extent wrong has been done; so a negative connotation would characterize the blank.

“Spurning” is despising; reject with contempt. Hence, (1) is the answer.

“And” after superficial in last part of the sentence gives clue for the second blank; which implies that the blank must be replaced by a word indicating similarity to superficial.

Moreover, “vaunted” (to boast, brag) characterizes the first blank, thereby giving a cogent meaning to the sentence. Hence, (5) is the answer.

Solicitious' (showing care, attention, or concern) in (3) and 'allegiant' (keeping faith) in (5) can be ruled out because they're positive words.

'Sometimes' in this sentence implies that the property that is to be filled in the blank is in contrast to what precedes it.

'Serenity' of the Indian countryside is more appropriate than 'landscapes' of the Indian countryside. Moreover, 'firsthand' conveys more sense to the context than 'gradually' on replacing the first blank. Hence, (2) is the answer.
