Which of the following is a complete sentence?

Correct Answer: D

Rationale: The correct answer is D, 'She ran through the park.' This sentence is a complete sentence as it contains both a subject 'She' and a predicate 'ran through the park.' Choices A, B, and C are not complete sentences because they lack either a subject, a predicate, or both. Choice A 'Under the bed.' lacks a verb or predicate, choice B 'Although he tried his best.' is a dependent clause and does not form a complete sentence on its own, and choice C 'Running through the park.' is a phrase without a subject or a complete predicate.

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: A

Rationale: The correct order for the sentence 'yesterday she went to the store' is 'She went to the store yesterday.' In English, the standard word order for a sentence is subject-verb-object-adverbial (time). Choice A is the correct answer as it follows this standard order. Choice B changes the order of the subject and object. Choice C changes the order of the adverbial and subject. Choice D changes the order of the subject and adverbial. Therefore, choices B, C, and D are incorrect.

Correct Answer: C

Rationale: The function of an adjective in a sentence is to describe or modify a noun. Adjectives provide more information about the noun they modify, such as its size, color, shape, etc. For example, in the sentence 'The tall building,' 'tall' is an adjective describing the noun 'building.' Choices A, B, and D are incorrect. Adjectives do not describe verbs (adverbs do that), connect clauses (conjunctions do that), or show action (verbs do that).

Correct Answer: B

Rationale: In the sentence provided, 'Singing' is a gerund, which is a verb form ending in -ing that functions as a noun. It represents the action of singing, but in this context, it acts as the subject of the sentence. Therefore, 'Noun' is the correct answer. 'Verb' (choice A) is incorrect because while gerunds are verb forms, in this sentence, 'Singing' is not acting as a verb. 'Adjective' (choice C) is incorrect as it describes a noun, which is not the case here. 'Pronoun' (choice D) is also incorrect as 'Singing' does not replace a noun in this sentence.
