Correct Answer: D

Rationale: 'Ridiculously' is an adverb in this sentence, modifying the adjective 'easy.' Adverbs typically modify adjectives, verbs, or other adverbs. In this case, 'ridiculously' is describing the adjective 'easy,' indicating the degree or manner of the adjective. Choices A, B, and C are incorrect. 'Ridiculously' is not a verb (choice A) as it is not expressing an action or state. It is not an interjection (choice B) since it is not an abrupt exclamation. Also, it is not an adjective (choice C) as it is not directly modifying a noun or pronoun.

Correct Answer: B

Rationale: 'Aisle' is the correct answer. A homophone is a word that is pronounced the same as another word but has a different meaning or spelling. In this sentence, 'I'll' is a homophone of 'aisle' as they sound the same but have distinct definitions and spellings. Choices A, C, and D do not fit the criteria of being homophones of 'I'll'.

Correct Answer: B

Rationale: The correct answer is 'B: Joyful.' 'Joyful' is a synonym for 'happy' as both words convey feelings of pleasure, contentment, and delight. Choice 'A: Sad' is incorrect as it is an antonym of 'happy,' representing feelings of sorrow or unhappiness. 'Angry' in choice 'C' and 'Tired' in choice 'D' are also incorrect as they represent different emotional states and do not share the same meaning as 'happy.'

Correct Answer: B

Rationale: The correct answer is B: 'It's a beautiful day outside.' 'It's' is the contraction for 'it is.' Choice A is incorrect as it should be 'It's' instead of 'Its.' Choice C is incorrect as the apostrophe should come before the 's' in the contraction. Choice D is incorrect as the use of 'is'' is grammatically incorrect.

Correct Answer: D

Rationale: The correct answer is D. A direct quotation from a reference source always requires a citation to give credit to the original author. Choices A, B, and C do not necessarily require citations. Choice A refers to information that is common knowledge or easily observed, which does not need a citation. Choice B pertains to summarizing information in one's own words, which should be attributed to the original source but does not require a direct citation. Choice C involves sharing a personal experience, which does not require a citation unless it includes specific data or information that needs to be attributed to a source.
