Correct Answer: C

Rationale: The prefix 'intra-' means 'within,' so 'intravenous' refers to something within veins. Choice A, 'Across veins,' is incorrect as 'intra-' does not indicate movement across but within. Choice B, 'Between veins,' is incorrect because 'intra-' does not imply a relationship between two separate veins. Choice D, 'Outside veins,' is incorrect as 'intra-' signifies something inside or within, not outside.

Correct Answer: B

Rationale: The error in capitalization is in option B. 'Uncle' should not be capitalized because it is not used as a proper noun in this context. It should be written as 'uncle.' In the other options, capitalization is correctly used for proper nouns like 'East Coast,' 'English Composition II,' and 'Jersey Shore,' making them the correct choices.

Correct Answer: C

Rationale: A compound sentence is made up of two independent clauses connected by a coordinating conjunction (such as 'and,' 'but,' 'so,' etc.) or a semicolon. In this case, 'The baby was sick' and 'I decided to stay home from work' are two independent clauses connected by the coordinating conjunction 'so.' Choice A is a simple sentence with one independent clause. Choice B is a complex sentence with an independent clause 'Marissa last saw Elena' and a dependent clause 'and talked to her this morning.' Choice D is also a simple sentence with one independent clause.

Correct Answer: D

Rationale: Sentence D is a compound-complex sentence because it contains two independent clauses ('Even though the puppy was much smaller than his mother' and 'his eyes were dark brown and shiny just like hers') and one dependent clause ('and his ears were long and floppy, too'). Choices A, B, and C do not meet the criteria for a compound-complex sentence as they lack a combination of independent and dependent clauses.

Correct Answer: B

Rationale: The correct usage of 'affect' in a sentence is as a verb meaning to influence something, as in 'The weather will affect our plans.' Choice A is incorrect because 'affect' should be 'effect,' which is a noun representing the result of an action. Choice C is incorrect as 'affect' should be 'effect' to describe a disorder. Choice D is incorrect because 'affect' should be 'effect' to convey the result of the news.
