What word is best to substitute for the underlined words in the following sentence? The nurse told Silvio's family that visiting hours were over, but Silvio's family could come back early tomorrow morning.

Correct Answer: A

Rationale: In the sentence, 'The nurse told Silvio's family that visiting hours were over, but Silvio's family could come back early tomorrow morning,' the second occurrence of 'Silvio's family' can be effectively substituted with the word 'them' to avoid repetition and improve clarity. Using 'them' in this context helps to make the sentence more concise and less redundant, enhancing the overall flow and readability. Choice B ('us') is incorrect as it would imply that Silvio's family could come back early tomorrow morning to the speaker and others, which is not the intended meaning. Choice C ('they') is incorrect as it would shift the subject from 'Silvio's family' to a third-person perspective, altering the original meaning. Choice D ('those') is incorrect as it does not appropriately refer back to 'Silvio's family' in a clear and concise manner.

Correct Answer: A

Rationale: The word 'because' indicates the reason or cause for something. In this context, it logically connects the meteorologist's forecast of rain with Sheila bringing her umbrella to work. The conjunction 'because' explains the relationship between the rain forecast and Sheila's action of bringing an umbrella, making it the most suitable word for the sentence. Choices B, C, and D do not fit the context as they do not provide a logical reason for Sheila's action.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is needed at the end of the sentence to indicate the completion of the thought and to make it a grammatically correct statement. The other options (comma, question mark, exclamation mark) do not fit the context of the sentence. In this case, a period is used to end a declarative sentence, stating a fact without needing any additional punctuation for the context provided.

Correct Answer: C

Rationale: The correct spelling is 'embarrassing.' It is spelled with two consecutive r's and two consecutive s's. Option C is the only choice with the correct spelling. Options A, B, and D all have incorrect spellings. 'Embarrasing' (Option B) is missing an 'r,' and 'Emberassing' (Option D) has an extra 'e' and a missing 'r' and 's.' Therefore, the correct answer is Option C.

Correct Answer: B

Rationale: The correct answer is 'to roll.' In this sentence, 'started' is followed by the infinitive form of the verb 'to roll.' The construction 'started to roll' indicates the beginning of the action of the wheelchair moving down the corridor. Choice A ('roll') is incorrect as it lacks the infinitive marker 'to' needed after 'started.' Choice C ('rolled') is incorrect as it is the past tense form of the verb, not suitable for the sentence's context. Choice D ('will roll') is incorrect as it indicates a future action, not the past action indicated by 'started.'
