Correct Answer: C

Rationale: The correct answer is 'C: Did well.' This phrase is commonly used to describe performance on an exam. 'Worked' does not fit the context of exam performance. 'Forgot' is incorrect as it implies forgetting something related to the exam. 'Done good' is grammatically incorrect; the correct form is 'done well.' Therefore, 'Did well' is the most appropriate choice in this context.

Correct Answer: A

Rationale: In this context, 'Envelopes' is the correct choice as it refers to the items (envelopes) that the mailperson is responsible for delivering. The other choices are incorrect: 'Mail' (Choice B) is too general and does not specify the items to be delivered, 'Block' (Choice C) is the location and does not make sense in the context of delivering mail, and 'Every' (Choice D) is an adjective that does not complete the sentence logically.

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.

Correct Answer: C

Rationale: The correct answer is 'C: Did well.' This phrase is commonly used to describe performance on an exam. 'Worked' does not fit the context of exam performance. 'Forgot' is incorrect as it implies forgetting something related to the exam. 'Done good' is grammatically incorrect; the correct form is 'done well.' Therefore, 'Did well' is the most appropriate choice in this context.

Correct Answer: D

Rationale: The correct answer is 'Were broken.' In this sentence, the subject 'glass in three of the windows' is plural, so the correct verb form should also be plural, which is 'were broken.' The verb 'broken' in the original sentence is in the past participle form, which is used correctly in the corrected answer choice 'D.' Choices A, B, and C are incorrect because they do not match the subject in number ('glass in three of the windows') and do not use the correct past participle form of the verb.
