Correct Answer: D

Rationale: In sentence D, the word 'part' functions as an adjective to modify the noun 'Irish.' It describes the Irish heritage of Ronaldo. The other choices use 'part' as a noun. In sentence A, 'part' is a noun referring to a role in a play. In sentence B, 'parts' is a verb indicating separating or dividing. In sentence C, 'part' is a noun referring to a contribution or role in the success of a project.

Correct Answer: C

Rationale: The suffix '-fy' means to make or cause to have. Each word listed-glorify, fortify, gentrify, acidify-indicates a process of transforming or altering something, making the common meaning related to causing or making. Choice A ('Marked by, given to') is incorrect as it does not reflect the action of making or causing. Choice B ('Doer, believer') is unrelated to the suffix -fy and does not capture its meaning. Choice D ('Process, state, rank') is also incorrect as it does not align with the consistent theme of causing or making evident in the words provided.

Correct Answer: A

Rationale: The topic sentence sets the stage for the discussion that follows. Choice A, 'The Civil War was a war that was not easily won, but hard fought,' is the most appropriate as it introduces the theme of the challenges faced during the Civil War and the determination required for victory. Choice B, 'The Civil War ended in 1865,' is a factual statement but does not lead into the paragraph content. Choice C, 'Jefferson Davis was the President of the Confederate States,' introduces a different historical figure not central to the paragraph. Choice D, 'Many countries have had civil wars,' is a broad statement not related to the specific context of the Civil War in the United States.

Correct Answer: D

Rationale: The comma after 'delicious' is unnecessary as it separates the adjective 'delicious' from the noun 'stew'. In this case, 'delicious' is describing the type of stew, so the comma should be removed to maintain correct sentence structure. The other commas in the sentence are correctly used to separate items in a list and after introductory phrases, making them necessary for clarity and grammatical correctness.

Correct Answer: C

Rationale: The given sentence, 'If it rains tomorrow, the picnic will be canceled,' is a complex sentence. It consists of an independent clause 'the picnic will be canceled' and a dependent clause 'If it rains tomorrow.' A simple sentence contains just one independent clause, a compound sentence contains two or more independent clauses, and a compound-complex sentence contains two or more independent clauses and at least one dependent clause. Therefore, choices A, B, and D are incorrect for this sentence.
