Correct Answer: A

Rationale: The correct answer is A, 'joyous.' 'Pensive' means engaged in deep or serious thought, often with a hint of sadness. The antonym 'joyous' represents a state of great happiness and delight, contrasting with the contemplative and somewhat melancholic nature of being pensive. Choices B, C, and D are incorrect. 'Thoughtful' is not an antonym but rather a synonym, meaning showing consideration or careful thought. 'Curious' and 'introspective' are also not antonyms; 'curious' means eager to know or learn something, and 'introspective' means examining one's own thoughts and feelings.

Correct Answer: A

Rationale: Alliteration is the repetition of the initial consonant sound in neighboring words. In the sentence 'The quick brown fox jumps over the lazy dog,' 'quick' and 'brown' both start with the 'k' sound, but only 'quick' aligns with the definition of alliteration as it repeats the 'k' sound found at the beginning of the words.

Correct Answer: B

The results - which makes 'results' a noun in this context. Choices A, C, and D are incorrect. 'Results' is not describing a verb, an adjective, or an adverb in the sentence; it is the object of the students' anticipation, indicating a noun.

Correct Answer: B

Rationale: An adverb modifies verbs, adjectives, or other adverbs. In this sentence, 'anxiously' describes how the patient 'waited'. Therefore, the adverb in the sentence is 'anxiously'. Choice A, 'waited', is a verb and not an adverb. Choice C, 'doctor's', is a possessive noun and not an adverb. Choice D, 'news', is a noun and not an adverb. The correct adverb that modifies the verb 'waited' in the sentence is 'anxiously'.

Correct Answer: B

Rationale: The correct way to punctuate dialogue is to enclose each speaker's words in quotation marks. Additionally, the question mark should be placed inside the closing quotation mark of the question. In this case, the correct answer is B as it adheres to the punctuation rules for dialogue. Each character's dialogue is correctly enclosed in quotation marks, and the question mark is appropriately positioned inside the closing quotation mark of the question. Choice A is incorrect as the question mark is placed outside the closing quotation mark of the question. Choice C is incorrect as it uses a comma instead of a period after 'she asked.' Choice D is incorrect as it uses a comma instead of a period after 'she asked' and incorrectly places the comma inside the closing quotation mark of the question.
