Correct Answer: B

Rationale: Choice B is incorrect due to the use of 'than' instead of 'then.' The correct word in this context is 'then' to indicate the order of actions. Choices A, C, and D are all grammatically correct. In choice A, the sentence structure is correct with a clear cause-effect relationship. Choice C is grammatically sound, describing the dietician's mistake. Choice D is also grammatically correct, showing a cause (the child feeling ill) leading to an effect (the nurse sending him home).

Correct Answer: B

Rationale: In this context, 'initial' means 'first,' referring to the first examination conducted by the doctor. The initial examination is the first assessment or evaluation performed on the patient. Therefore, 'first' is the correct meaning in this sentence. 'Complete' (choice A) is incorrect as initial does not imply completeness, 'incomplete' (choice C) is incorrect as initial does not mean unfinished, and 'discharge' (choice D) is unrelated to the concept of an initial examination.

Correct Answer: B

Rationale: The correct answer is 'Me.' In this sentence, 'me' is the correct object pronoun to use after the preposition 'to.' 'Myself' is a reflexive pronoun used when the subject and object of the sentence refer to the same person, which is not the case here. 'Us' is the object form of 'we,' which is incorrect in this context. Therefore, 'Me' is the most suitable choice.

Correct Answer: D

Rationale: The correct answer is D: 'I wore a white shirt and dark jeans to show my goat at the country fair.' 'Wore' is the correct past tense form of 'wear.' Choice A is incorrect as 'seen' should be 'saw,' which is the correct past tense of 'see.' Choice B is incorrect as 'sung' should be 'sang,' the correct past tense of 'sing.' Choice C is incorrect as 'ran' is the correct verb, but the question specifically asks for the correct use of a verb, not just any verb.

Correct Answer: A

Rationale: The correct answer is A. 'Ain't' is not grammatically correct in formal writing or speech; it should be 'isn't.' 'Ain't' is considered slang and is not appropriate for formal contexts. The other choices ('During,' 'Sure,' 'Playoff') are used correctly in the sentence.
