Fill in the Blanks

Police is a collective noun that is always treated as plural in English grammar. Even though it refers to a group, it requires the plural verb 'have', not 'has'. 'The police have made no arrests' is correct.

This is a poorly constructed question. 'Tidings' is a legitimate word meaning news or information (as in 'glad tidings'), but 'tide' refers to the ocean's rhythmic rise and fall. Neither 'tide' nor 'tidings' fits well with 'came very late'. The question seems to be testing whether students know the irregular plural of 'tiding' (which is rarely used in modern English), but the context is awkward.

The phrase 'give thanks to God' is correct. 'Thanks' functions as a noun here, while 'thank' would need to be part of a verb phrase like 'thanked' or 'thanking'. The blank requires a noun after the verb 'give'.

Option 1 is correct.

In the context of sports like cricket, 'innings' is the correct noun form referring to a team's turn to bat. While 'inning' is used in baseball, 'innings' is the standard term in cricket and the form most commonly tested.

'Alms' is the correct noun form meaning charity or money given to poor people. It's an uncountable noun that always takes the plural form, even when referring to a single act of giving.

When 'Economics' refers to the subject or academic discipline, it takes a singular verb ('is'). This follows the rule for names of academic subjects and fields of study ending in -s.

The correct option is (4). Other options do not make sense.

‘Tempers ran high’ indicates anger and resentment.

'Qualified obedience' doesn't make any sense. Only, 'downright and complete' make sense in the first blank. In the 2^nd blank, 'inane' doesn't fit as it means silly. Only, 'compliant' suits as it means obedient.

No preposition is needed with ‘better’, ‘need not’, etc.

'So' is used for a reason that has just been stated. 

New population would need more restaurants, so 'opening' fits here.

Only 'great' makes sense here.

As flexibilty is needed in gymnastics, it suits the statement best. Olympics are games and not a skill.
