Correct Answer: A

Rationale: The correct answer is 'A: Head.' The phrase 'on the head' is a prepositional phrase indicating where the person was hit. 'Head' is the correct noun to complete the sentence. Choices B, C, and D are incorrect because they either add unnecessary articles ('a' or 'the') or incorrectly use the preposition 'on' before 'head.' The correct structure is 'hit on the head,' without any additional articles.

Correct Answer: B

Rationale: The correct answer is B, 'Volatile.' In this context, 'labile' means having an unpredictable or changeable condition. Choice A, 'Fevered,' is incorrect as it relates to having a fever, not the intended meaning of 'labile.' Choices C and D, 'Stomach' and 'Vision,' are unrelated to the context of the sentence and do not reflect the meaning of 'labile' as 'volatile.'

Correct Answer: D

Rationale: The correct phrase to complete the sentence is 'In spite of.' This phrase is used to indicate that an action is taken despite a particular circumstance or feeling. In this case, she went to the party in spite of her dislike for the host, meaning she attended the party regardless of her negative feelings towards the host. Choice A, 'Despite of,' is incorrect as the correct phrase is 'Despite,' without the preposition 'of.' Choice B, 'Even though,' is not the best fit in this context as it does not express the contrast between attending the party and disliking the host as effectively as 'In spite of.' Choice C, 'Although,' is also not the most suitable choice as it is used to introduce a contrast, but 'In spite of' provides a stronger emphasis on the contradiction between attending the party and disliking the host.

Correct Answer: C

Rationale: The correct answer is C: 'cause it to happen.' 'Implement' means to put something into action or cause it to happen. Choices A, B, and D are incorrect because they do not reflect the meaning of 'implement.' Preventing something from occurring (Choice A), emphasizing the importance of something (Choice B), and following something from beginning to end (Choice D) are all different actions or concepts that do not align with the definition of 'implement.'

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.
