The blue whale is the largest animal _________ the world.
- A. In
- B. On
- C. Of
- D. At
Correct Answer: B
Rationale: The correct answer is 'B: On.' The phrase 'on the world' is incorrect. The preposition 'on' is used to indicate position or location, making it the appropriate choice in this context. Therefore, the correct sentence should read: 'The blue whale is the largest animal on the world.' Choices A, C, and D are incorrect because 'in,' 'of,' and 'at' are not suitable prepositions to describe the blue whale's size in relation to the world.

Children generally ______ with others of the same size and age.
- A. Play
- B. Plays
- C. Played
- D. Playing
Correct Answer: A
Rationale: The correct answer is 'Play' because 'Children' is a plural subject and requires the base form of the verb. When referring to a plural subject like 'Children,' the verb should be in its base form without an added 's' or 'ed.' In this context, 'Play' is the appropriate form to use to match the subject 'Children.'
Choice B, 'Plays,' is incorrect because it is the singular form of the verb and does not agree with the plural subject 'Children.' Choice C, 'Played,' is incorrect as it is the past tense form of the verb and does not fit the present tense context of the sentence. Choice D, 'Playing,' is incorrect as it is the present participle form of the verb and does not match the simple present tense needed in the sentence.
If they _________ that the weather was going to be so bad, they wouldn't have gone to the beach.
- A. Know
- B. Knew
- C. Had known
- D. Were knowing
Correct Answer: C
Rationale: The correct answer is 'C: Had known.' In this sentence, the structure is a third conditional, which is used for unreal situations in the past. 'Had known' is the correct past perfect form that matches the conditional structure. It indicates that if they had possessed the knowledge about the bad weather in advance, they wouldn't have gone to the beach. Options A, B, and D do not correctly fit the past perfect tense required in this context. 'Know' (Option A) is present tense, 'Knew' (Option B) is simple past tense, and 'Were knowing' (Option D) is incorrect and does not convey the intended meaning of the sentence in the context of a third conditional.
I am looking forward to ___________ on a vacation next month.
- A. Go
- B. Going
- C. Be going
- D. Going to go
Correct Answer: B
Rationale: In this sentence, the correct form is the gerund 'going' after the preposition 'to.' The gerund form is used after prepositions to indicate an action or state. Therefore, 'Going' is the correct choice to complete the sentence. Choice A ('Go') is incorrect because it is not the gerund form required after 'to.' Choice C ('Be going') is incorrect as it is not the standard form used in this context. Choice D ('Going to go') is redundant and unnecessarily wordy.
Scissors should never be ___________ by the handle.
- A. Carry
- B. Carries
- C. Carried
- D. Carrying
Correct Answer: C
Rationale: 'Carried' is correct because 'should never be' requires the past participle form of the verb 'carry' to complete the sentence properly. The sentence is in the passive voice, indicating that the action is being done to the scissors, not by them. Choices A, B, and D are incorrect as they do not form the correct past participle form needed in this context.
Identify the dependent clause in this sentence: The mother dog left her bed as soon as the puppies were asleep.
- A. As soon as the puppies were asleep
- B. Left her bed as soon as
- C. The puppies were asleep
- D. The mother dog left her bed
Correct Answer: A
Rationale: The correct answer is A: 'As soon as the puppies were asleep' is the dependent clause in the sentence. It functions as an adverbial clause, indicating a time relationship with the action of the mother dog leaving her bed. Dependent clauses rely on independent clauses to form complete sentences and cannot stand alone. Choice B is incorrect because it separates the dependent clause. Choice C is incorrect as it is a noun phrase. Choice D is incorrect as it is an independent clause.
