Correct Answer: C

Rationale: The sentence is a direct question as the speaker is asking if the person will send a postcard from Germany. Therefore, the correct punctuation mark to use at the end of a question is a question mark. An exclamation mark (Choice D) is used to convey strong emotion or surprise, which is not the case here. A period (Choice A) is used for declarative statements. A colon (Choice B) is used to introduce a list or explanation, which is not needed in this context.

Correct Answer: A

Rationale: The sentence 'Neither of the cars is parked on the street' is incorrect in terms of subject-verb agreement. The subject 'Neither' is singular, so the verb should also be singular, which should be 'is' instead of 'are.' The correct sentence should be 'Neither of the cars is parked on the street.' Choices B, C, and D demonstrate correct subject-verb agreement. In choice B, 'Both' is plural and agrees with the plural verb 'are.' In choice C, 'Any' is singular and agrees with the singular verb 'are.' In choice D, 'Each' is singular and agrees with the singular verb 'is.'

Correct Answer: C

Rationale: The correct plural form of 'cactus' is 'cacti' according to the English language rules for forming plural nouns ending in -us. The word 'cacti' is the plural form of 'cactus,' which follows this particular rule. Choice A 'Tomatoes' is incorrect because the correct plural form of 'tomato' is 'tomatoes,' not 'tomatos.' Choice B 'Analysis' is incorrect as it is already the plural form. Choice D 'Criterion' is incorrect as its plural form is 'criteria,' not 'criterion.'

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: C

Rationale: The correct answer is C because 'hang out' and 'chill' are colloquialisms, informal expressions commonly used in casual conversations. Choice A is a polite and formal way to ask for a meeting, devoid of colloquial language. Choice B is a straightforward expression of enjoyment without any colloquialisms. Choice D is a polite and formal statement that does not contain any colloquial language.
