The idiom 'to beat the air' means to continue doing something despite it seeming pointless or futile, which matches option C. The other options do not correctly define this phrase.

The correct preposition to use with 'houses' in relation to an island is 'on.' This is because an island is considered a surface or piece of land, and 'on' is used for locations situated on top of such surfaces (e.g., islands, streets, shores). Using 'around' would imply the houses are surrounding the island, which is not the intended meaning here. 'In' suggests being inside an enclosed space, which does not fit the open geographic nature of an island. Therefore, the sentence should read: 'The island is so small that there are only five houses on it.'

The correct preposition to indicate a time period during which something happens is 'in'. Therefore, 'in the first half of the match' is correct, as it specifies when the local team scored the goals.

The term 'Topophilia' refers to a strong sense of love or emotional connection to a place. The other options do not relate to love for a place.

The word 'abominate' means to detest or loathe intensely. Therefore, its antonym would be a word expressing love or strong liking, which is option A: 'love'. Options B, C, and D all mean dislike or hatred, so they are synonyms, not antonyms.

The subject 'mathematics' is treated as a singular noun in English, so the correct verb form is 'is'. Therefore, 'His mathematics is good.' is correct.

The correct preposition to indicate that she slept in the time span of the movie is 'during.' 'While' is a conjunction and cannot directly fill the blank here. 'At' is incorrect because it refers to a specific point in time, not a duration. 'None of the above' is incorrect since 'during' is the right choice.

The verb 'want' is a stative verb and is not typically used in the continuous form. Therefore, 'wants' is the correct choice to complete the sentence.

The idiom "All and Sundry" means everyone or all people without exception. It refers to including every person concerned.

The sentence "The research study is an eye-opener and _____ us with the problems of poor nations" requires a verb form that agrees with the present tense verb "is" and fits grammatically. The phrase should be "attempts to acquaint" or a similar present tense form. Option A "Attempted to acquaint" is past tense and does not agree with "is." Option B "Attempting to acquaint" is a present participle and does not fit well here. Option C "Attempts at acquainting" is closest to a correct present tense form, though "attempts to acquaint" would be better. Option D "Attempt to acquaint" is an infinitive and does not fit grammatically. Therefore, the best choice is C. The original answer A is incorrect because it does not agree in tense with "is." This is confirmed by standard English grammar rules and usage examples.

The analogy compares an emotion to its cause or trigger. Fear is caused by a threat, so anger is caused by provocation. Provocation is the direct stimulus or cause that triggers anger, making it the best fit for the analogy. 'Force' is less directly related to the cause of anger and more associated with physical power or coercion, which is not the primary trigger of anger in the analogy context. Therefore, 'Provocation' is the correct answer.

The phrase 'put off' means to postpone or delay something, which fits the context of a meeting being delayed by the Chairman. The other options do not convey the correct meaning in this context.

The word 'yank' primarily means to pull or jerk something suddenly and forcefully. Among the given options, 'Push' is the opposite action, 'Gluttonous' is unrelated, and 'Hitch' generally means to catch or move by jerks but is not a synonym for 'yank.' Therefore, none of the options A, B, or C correctly define 'yank.' The correct choice is 'D' (None of these).

The word 'trammel' means a restriction or obstacle that prevents free action, so 'Obstacle' is the correct synonym among the options provided.

The word 'revealed' means made known or disclosed. Its antonym is 'concealed,' which means kept hidden or secret. The other options do not directly oppose the meaning of 'revealed.'

The word "pit" refers to a hole or a low point, so its antonym is "peak," which means the highest point or summit. The other options do not represent opposites of "pit."
