Choice B is the best answer. This choice uses paired punctuation in the form of two commas to set off the nonessential phrase “in the process.”
Choice A is incorrect. The phrase “in the process” is a nonessential element and needs to be set off with paired punctuation. We need a comma after “and” to match the one after “process.”
Choice C is incorrect. The phrase “in the process” is a nonessential element and needs to be set off with paired punctuation, so we would need a dash after “and” to match the one following “process.”
Choice D is incorrect. The phrase “in the process” is a nonessential element and needs to be set off with paired punctuation. We would need a comma after “process” to match the one following “and.”

The convention being tested is end-of-sentence punctuation. This choice correctly uses a question mark to punctuate the interrogative clause “could the blueberries thrive,” which asks a direct question at the end of the sentence. Choice A is incorrect because a period can’t be used in this way to punctuate an interrogative clause, such as “could the blueberries thrive,” at the end of a sentence. Choice B is incorrect because the context requires an interrogative clause. The declarative clause “the blueberries could thrive” incorrectly indicates that it was known that the blueberries could thrive in alkaline soil, whereas Michel had yet to find this out.

In this choice, the commas after “nickname” and “however” are correctly used to separate the supplementary adverb “however” from the main clause (“Scott-Heron…nickname”) on one side and the supplementary participial phrase (“feeling…bluesologist”) on the other. Choice A is incorrect because it fails to mark the boundary between the supplementary adverb “however” and the supplementary phrase (“feeling…bluesologist”).

Choice D is incorrect because a semicolon can’t be used in this way to join the main clause (“Scott-Heron…nickname”) and the supplementary word and phrase (“however” and “feeling…bluesologist”).

A colon can only be used at the end of an independent clause, and typically introduces further explanation that expands upon the first clause, which makes a colon the perfect choice here. Choice B is incorrect. This choice results in a punctuation error. “Sequencing…dental plaque” can’t stand on its own as a sentence, and so it can’t be linked to the independent clause “a team…tried something new” with a semicolon. Only two independent clauses can be connected in this way. Choice C is incorrect. This choice results in a punctuation error.

This choice correctly uses a comma to mark the boundary between the introductory supplementary phrase (“By linking the Hudson River to Lake Erie”), which identifies how the canal reduced transport time, and the main clause (“the canal reduced transport time to nine days and cut costs to six dollars per ton”).
Choice A is incorrect because a semicolon can’t be used in this way to mark the boundary between a supplementary phrase (“By…Erie”) and the main clause (“the canal…ton”).

Choice C is the best answer. The convention being tested is the use of punctuation between titles and proper nouns. No punctuation is needed to offset the proper noun “Yuree Lee” form the title “plant cell biologist” that describes Lee.
Choice A is incorrect because no punctuation is needed.

The convention being tested is the coordination of main clauses within a sentence. The semicolon is correctly used to join the first main clause (“To humans…prey”) and the second main clause (“rather… approach”). Further, the comma after the adverb “rather” is correctly used to separate the adverb from the main clause (“the brightly…approach”) it modifies, logically indicating that the information in this clause (how the spider’s behavior appears to humans) is contrary to the information in the previous clause (how the spider’s behavior does not appear to humans). Choice A is incorrect because it results in a comma splice. Without a conjunction following it, a comma can’t be used in this way to join two main clauses. Choice B is incorrect because it results in a run-on sentence. The two main clauses are fused without appropriate punctuation and/or a conjunction. Choice C is incorrect.

Choice A is incorrect because when coordinating two longer main clauses such as these, it’s conventional to use a comma before the coordinating conjunction.
