Fill in the Blanks

 A thousand bushels is a plural number that will take plural verb 'were'.

The phrase after 'or', i.e. 'his sister' takes a singular helping verb after it. Only, 'has' fits here.

The sentence is in present continous tense, therefore we must use the word "uses".

The correct idiom is 'thrown into shambles,' meaning a state of disorder or ruin. 'Shambles' is the correct plural form of the noun. The other spellings (shamble, shambel, shambels) are incorrect.

Here, the word 'year' is preceded by a numerical figure (five) but succeeded by a noun (plan). In this case, the word 'year' will be written in singular. The phrase will be written as 'five-year plan'.

There are M.A.'s among the applicants.

Here, a denomination is preceded by a numerical figure (ten) but succeeded by a noun (note). So, the denomination will be written in singular, i.e. 'ten-rupee notes'.

His score was one century and a half. 

Truck after truck crossed the prohibited line. 

Indian forces are strong enough to face the challenge.

House after house, was looted by the dacoits.

The sentence requires a possessive pronoun that can function independently as the object of the preposition 'of'. 'Mine' is a possessive pronoun (like 'yours', 'his', 'hers') that can stand alone: 'A friend of mine' = 'One of my friends'. 'His', 'him', and 'them' are either possessive determiners (requiring a following noun: 'his friend') or object pronouns. This pattern 'a [noun] of [possessive pronoun]' is a fixed English construction for expressing relationships.

The correct adjective form is 'dependable' meaning reliable or trustworthy. It follows the standard English suffix '-able' meaning 'capable of being' (depend-able = capable of being depended on). Options B, C, and D contain spelling errors: 'dependible' incorrectly substitutes 'i' for 'a', 'depending' is a present participle (verb form) not an adjective, and 'dependble' omits the vowel entirely. The correct pattern is that adjectives from verbs ending in consonant + silent 'e' typically use '-able' (remarkable, dependable, lovable).

Preposition such as between should be followed by an objective pronoun (such as me, him, her and us) rather than a subjective pronoun (such as I, he, she and we).

The pronoun 'who' is correct because it serves as the SUBJECT of the clause 'who the country will decide is to be considered responsible.' The entire clause 'who the country will decide is to be considered responsible' is the object of 'say,' but within that nested structure, 'who' is the subject of 'is.' The nominative form is required for the subject position.
