Correct Answer: A

Rationale: The correct answer is 'apprehensive.' In the context of an upcoming presentation, being apprehensive implies a sense of worry or nervousness. This aligns well with the situation where one might feel uneasy or concerned about their upcoming presentation. The word 'bored' (choice B) is incorrect as it does not convey the right emotion for this context. 'Excited' (choice C) and 'relieved' (choice D) do not match the expected sentiment of worry or nervousness associated with an upcoming presentation, making them incorrect choices.

Correct Answer: C

Rationale: The determiner in the sentence is 'few.' Determiners specify the quantity or identity of a noun. In this case, 'few' indicates the number of birds present. Choice A, 'happily,' is an adverb modifying a verb or an adjective, not a determiner. Choice B, 'branches,' is a noun referring to parts of a tree, not a determiner. Choice D, 'tree,' is a noun identifying the main subject of the sentence, not a determiner.

Correct Answer: B

Rationale: The correct answer is B: 'To bite off more than one can chew' means to take on more than one can handle or to undertake a task exceeding one's capabilities. This idiom warns against overcommitting oneself and facing difficulties in managing the workload effectively. Choice A, 'To be overly confident,' is incorrect as the idiom implies a situation of overestimating one's capacity rather than confidence. Choice C, 'To be easily discouraged,' is not related to the idiom's meaning, which focuses on task difficulty rather than emotional response. Choice D, 'To be meticulous in planning,' is not accurate as the idiom refers to the execution of tasks rather than the planning phase.

Correct Answer: A

This aligns well with the situation where one might feel uneasy or concerned about their upcoming presentation. The word 'bored' (choice B) is incorrect as it does not convey the right emotion for this context. 'Excited' (choice C) and 'relieved' (choice D) do not match the expected sentiment of worry or nervousness associated with an upcoming presentation, making them incorrect choices.

Correct Answer: A

Rationale: The correct answer is A, Metaphor. A metaphor is a figure of speech that directly compares two unlike things by stating that one thing is another. In the phrase 'a heart of gold,' the good nature of a person is being directly compared to gold, indicating that the person is kind, valuable, and precious, much like gold. This comparison is not using 'like' or 'as,' which would make it a simile, but rather it is a direct assertion, making it a metaphor. Simile involves comparing two things using 'like' or 'as,' which is not present in this phrase. Hyperbole is an exaggeration, which is not the case here. Personification gives human qualities to non-human entities, which is also not occurring in 'a heart of gold.'
