Fill in the Blanks

Cavalry refers to soldiers on horseback as a collective group or military unit. Collective nouns can take either singular or plural verbs depending on context, but when referring to the soldiers themselves (not the unit as a whole), 'cavalry' takes the plural verb 'are.' This emphasizes the multiple individuals in the group.

Jewellery is an uncountable noun in English (spelled 'jewelry' in American English). It refers collectively to ornaments and cannot be pluralized. We say 'pieces of jewellery' but never 'jewelleries.' The word is always used in the singular form regardless of quantity.

The phrase 'several ___ of shoes' requires the plural form 'pairs' because 'several' indicates more than one. 'Pair' is the singular form. 'Pairs' is the correct plural of 'pair' when referring to multiple sets of two. The other options are misspelled or incorrect verb forms.

Gentry refers to people of good social position or class as a collective group. It is an uncountable noun that doesn't change form in the plural. We use 'gentry' for both singular and plural, similar to how 'family' or 'clergy' work. 'Gentries' and other spellings are incorrect.

In the sentence structure 'All the ___ were happy,' we need the subject. 'People' is the correct plural form of 'person.' 'Peoples' exists but has a specific meaning - it refers to distinct ethnic groups or nations (e.g., 'the peoples of Europe'), which doesn't fit here. The other options are misspelled.

Information is an uncountable noun in English and never takes a plural form. We always use 'information' regardless of how much we have. 'Informations' is incorrect in standard English. Note that there is a spelling error in the question itself - 'recieve' should be 'receive.'

The sentence requires the plural form because of 'four,' indicating multiple sets. 'Pairs' is the correct plural of 'pair.' 'Pair' is singular, while 'paired' is a past tense verb or adjective, and 'paires' is misspelled. When counting more than one, we always use the plural form.

Score can mean a group of 20, so 'three score and ten' equals 70 (3×20+10=70). This is a classic expression from the Bible.

When a specific number like 'three' precedes 'thousand', it stays singular. We say 'three thousand workers', not 'three thousands'.

News is an uncountable noun that takes the singular verb 'is'. This is a common proverb meaning that not receiving information means things are probably fine.

Scores of is an idiom meaning 'a large number of'. The verb 'have been' agrees with the plural noun 'houses'. Score here means twenty, but 'scores of' means many dozens.

Without a specific number, we use the plural form 'thousands' when referring to an indefinite large quantity. 'Thousands of workers' means a very large number of workers.

Swine is an irregular plural noun that doesn't change form between singular and plural. Like sheep or deer, swine can refer to one or many animals. 'Herd of swine' is the correct collective expression.

The word ‘ruins’ indicates that remains are being seen. One is forced to reflect on the fact that nothing is permanent and human efforts do not last long. The ruins show that ‘dearth’ and ‘durability' are incorrect. ‘Humility’ does not connect with ‘ruins’. ‘Ruins’ does not connect with ‘elusiveness’.

The sentence can either be positive or negative. For this a pair of negative or positive words is required. If we use praised or endorsed or appreciated, no corresponding positive word is there among the choices. With criticised, we do not have a corresponding negative word in ‘pacified’. So, we have to use negative pair of words, which is found in option 1.
