Identify the article in the following sentence: The delicious cake was enjoyed by everyone at the party.

Correct Answer: C

Rationale: The correct answer is 'C - the.' Articles ('a,' 'an,' and 'the') indicate specificity of a noun. In this sentence, 'the' specifies that there is one particular cake being discussed. Choice A ('cake') is incorrect as it is the noun being modified by the article. Choice B ('was') is a verb and not an article. Choice D ('enjoyed') is also a verb and not an article.

Correct Answer: C

Rationale: The present participle form of a verb is used to indicate continuous or ongoing action. In this case, 'running' is the present participle of the verb 'run.' It shows that the action is in progress, unlike the past tense 'ran' or the simple present 'runs.' 'Runner' is a noun derived from the verb but not the present participle form.

Correct Answer: C

Rationale: The correct answer is 'C: enthusiasm.' The noun form of the adjective 'enthusiastic' is 'enthusiasm.' Nouns are often formed from adjectives by changing the suffix; in this case, '-ic' in 'enthusiastic' changes to '-m' in 'enthusiasm.' 'Entusiastic' is an adjective and does not function as a noun. 'Enthusiastically' is an adverb as it describes how something is done, not a noun. 'Enthuse' is a verb and does not represent the noun form of 'enthusiastic.' It is important to understand the relationships between different parts of speech when analyzing word forms.

Correct Answer: B

Rationale: The correct answer is 'B' because in the present tense, the third-person singular form of the verb 'paint' is 'paints.' When conjugating verbs, it is essential to match the verb form with the subject. 'Paints' is the correct form for the third-person singular subject 'artist' in this sentence. Choices 'A,' 'C,' and 'D' are incorrect. 'A' is in the past tense, 'C' is a gerund form, and 'D' is a noun, not a verb form, which does not match the tense and subject in the sentence.

Correct Answer: B

Rationale: The correct answer is 'B' - 'the guests chatted and enjoyed the music.' An independent clause expresses a complete thought and can stand alone as a sentence. It typically includes a subject and a verb and does not rely on another clause to form a complete sentence. In this sentence, 'the guests chatted and enjoyed the music' fits this criteria, making it the independent clause. Choices A and C are incorrect as they are dependent clauses, starting with a subordinating conjunction 'While,' which shows they cannot stand alone as complete sentences. Choice D is also incorrect as it lacks the word 'the' before 'enjoyed,' making it grammatically incomplete.
