Which phrase is NOT used correctly in the sentence?

Correct Answer: A

Rationale: The correct answer is A. "Do to" should be corrected to "due to" in this context. The sentence should read, "The client's hospital stay was prolonged, due to a superinfection." The phrase "due to" is the appropriate choice to indicate the cause of the prolonged hospital stay. Choices B, C, and D are all used correctly in the sentence and do not contain any errors.

Correct Answer: A

Rationale: The correct answer is A: 'Is.' In this sentence, 'Economics' is being treated as a singular subject, so the verb should also be singular. 'Is' is the correct singular form of the verb to agree with the singular subject 'Economics.' Choice B, 'Been,' is incorrect because it is the past participle form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice C, 'Am,' is incorrect because it is the first-person singular form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice D, 'Are,' is incorrect because it is the plural form of the verb 'be' and does not agree with the singular subject 'Economics.'

Correct Answer: A

Rationale: The correct contraction for 'will not' is 'won't'. 'Willn't' (Choice B) is not a standard contraction in English. 'Wouldn't' (Choice C) is the contraction for 'would not,' not 'will not.' 'Will'nt' (Choice D) is not a recognized contraction in English. Therefore, 'won't' is the correct choice as the contraction for 'will not.'

Correct Answer: D

Rationale: The correct answer is D. The phrase 'Went form' contains a typographical error. It should be 'went from' to indicate the change in condition correctly. Choice A 'To a,' choice B 'Very strong,' and choice C 'Being' are grammatically correct and do not contain any typographical errors in the given sentence.
