Correct Answer: B

Rationale: The sentence is in past tense ('As the concert ended'). Therefore, the correct verb form to use is 'asked,' as it agrees with the past tense of the sentence. Choice A is incorrect because 'ask' is not in agreement with the past tense context. Choice C is incorrect because 'have asked' is present perfect tense, not past tense. Choice D is incorrect because 'are asking' is present continuous tense, not past tense.

Correct Answer: C

Rationale: The word 'Although' is the correct choice as it is used to introduce a contrast between two ideas. In this sentence, it highlights the unexpected nature of Octavia being taller than her classmates despite being the youngest member of her class. This conjunction effectively conveys the discrepancy between her age and height in the context of the sentence. Choice A ('Despite') indicates a contradiction or contrast but does not capture the nuance of unexpectedness present in the sentence. Choice B ('Since') implies a causal relationship, which is not the intended meaning. Choice D ('Provided') suggests a condition or stipulation, which is not suitable for the context of the sentence. Therefore, 'Although' is the most appropriate choice.

Correct Answer: C

Rationale: The correct answer is 'C: receive.' In this sentence, 'receive' is the infinitive form of the verb that should follow the preposition 'to.' Therefore, the sentence should read: 'Sadie and her mother were excited to receive the award.' 'Be received' (A) is not appropriate in this context as it changes the passive voice. 'Receiving' (B) is a gerund form and does not fit after 'to.' 'Have been received' (D) is in the wrong tense and does not suit the sentence structure.

Correct Answer: C

Rationale: In this sentence, the correct word to use is 'them.' The subject of the sentence is 'the intern and another person,' indicating more than one individual. Therefore, the pronoun 'them' is the appropriate choice to refer to multiple people engaged in folding the bandages. Choice A ('us') is incorrect as it refers to the speaker and the intern, not the intern and another person. Choice B ('he') is singular and does not match the plural subject of the sentence. Choice D ('her') is also singular and does not agree with the plural subject 'the intern and another person.'

Correct Answer: B

Rationale: The correct answer is B: 'Comma.' In the sentence, a comma is needed to separate the independent clauses 'I will check the supply closet' and 'you can look in the laundry.' This comma helps to indicate a pause between the two related but separate actions that each person is taking. Choice A (Period) is incorrect because a period would create two separate sentences. Choice C (Colon) is incorrect as a colon is used to introduce a list or explanation. Choice D (Semicolon) is incorrect as a semicolon is used to connect two closely related independent clauses without a coordinating conjunction.
