Choice D is the best answer. The convention being tested is punctuation use between sentences. In this choice, the period after “walls” is used correctly to mark the boundary between the first sentence (“In…walls”) and the second sentence (“With…techniques”), which starts with a supplementary phrase.
Choice A is incorrect because it results in a comma splice. A comma can’t be used in this way to mark the boundary between sentences. Choice B is incorrect because it results in a run-on sentence. The sentences (“In…walls” and “with…paintings”) are fused without punctuation and/or a conjunction. Choice C is incorrect. Without a comma preceding it, the conjunction “so” can’t be used in this way to join sentences.

Choice D is the best answer. The word “falling” occurs in the middle of a clause and isn’t part of a supplement, so we don’t need any punctuation after it. We can see this more clearly if we simplify the rest of the sentence: “The reason seeds appear to float while falling is that their plumes enhance drag.” .
Choice A is incorrect. This doesn’t complete the text in a way that conforms to the conventions of Standard English.

Choice B is the best answer. There are two independent clauses in the sentence, each with a subject and a verb: “many…were skeptical” and “historians have determined….” These clauses can be grammatically joined by a comma and the coordinating conjunction “but.”
Choice A is incorrect. This choice results in a run-on sentence, which occurs when two independent clauses are joined without punctuation. Two independent clauses can’t be joined by just the coordinating conjunction “but.” A comma would also be required. Choice C is incorrect. This choice creates a punctuation error called a comma splice. This sentence contains two independent clauses (“Many…were skeptical” and “historians have determined…”). A comma alone can’t join two independent clauses. That requires a comma and a coordinating conjunction. Choice D is incorrect. This choice results in a run-on sentence, which occurs when two independent clauses are joined without punctuation. This sentence contains two independent clauses (“Many…were skeptical” and “historians have determined…”), which need to be either joined by a semicolon, joined by a comma and a coordinating conjunction, or separated by a period.

Choice B is the best answer. The convention being tested is the punctuation of items in a series. The comma after “themselves” is used conventionally to separate the first item (“they can clone themselves”) and the second item (“enter a dormant state in times of drought”) in the series of things mosses can do.
Choice A is incorrect because a semicolon can’t be used in this way to separate items in a simple series such as this. Choice C is incorrect because it results in a rhetorically unacceptable sentence fragment beginning with “And enter.” Choice D is incorrect because it fails to use appropriate punctuation to separate the first and second items in the series.

Choice A is the best answer. This choice uses a comma and a coordinating conjunction (“and”) to join two independent clauses (“The Tantaquidgeon…Tribe” and “Today…country”).
Choice B is incorrect. This choice results in a grammar error known as a run-on sentence. The clauses before and after “Tribe” are both independent, so they need to be separated with some sort of punctuation. Choice C is incorrect. This choice results in a grammar error known as a run-on sentence. The clauses before and after “and” are both independent, so they can’t be linked with just a conjunction. A comma would also be required. Choice D is incorrect. This choice results in a grammar error called a comma splice. The clauses before and after “Tribe” are both independent, so they can’t be linked with just a comma. A coordinating conjunction like “and” or “but” would also be required.

Translated’, “true”], ], ‘explanation’: ‘Correct Answer: D
Choice D is the best answer. The convention being tested is punctuation use between sentences. In this choice, the period is used correctly to mark the boundary between one sentence (“The poem…exclamation”) and another sentence that begins with a supplementary element (“Translated…poem”). The supplementary element “translated as ‘hark!’ or ‘listen!’ in some versions” modifies the subject of the second sentence, “the word” (referring to hwæt).
Choice A is incorrect because it results in a comma splice after “exclamation.” A comma can’t be used in this way to mark the boundary between sentences. Choice B is incorrect. Without a comma preceding it, the conjunction “and” can’t be used in this way to join sentences. Choice C is incorrect because it results in a comma splice after “versions.” A comma can’t be used in this way to mark the boundary between sentences.

Choice D is the best answer. The convention being tested is punctuation between a verb and a prepositional phrase. No punctuation is needed between the verb “blend” and the prepositional phrase “with Charlie Adams’s delightfully catchy vocal melodies.” The prepositional phrase completes the idea of the sentence, explaining with what Koperqualuk’s guitar riffs blend.
Choice A is incorrect because no punctuation is needed between the verb and the prepositional phrase. Choice B is incorrect because no punctuation is needed between the verb and the prepositional phrase. Choice C is incorrect because no punctuation is needed between the verb and the prepositional phrase.

Lagos; A Kind of Marriage,’, “true”], [‘C. Lagos, A Kind of Marriage:’, “false”], [‘D. Lagos; A Kind of Marriage’, “false”], ], ‘explanation’: ‘Correct Answer: B
Choice B is the best answer. The convention being tested is the punctuation of items in a complex series (a series including internal punctuation). In this choice, the semicolon after “Lagos” is conventionally used to separate the first item (“The Joys…Lagos”) and the second item (“A Kind…Nigeria”) in the series. Further, the comma after “Marriage” correctly separates the title “A Kind of Marriage” from the supplementary phrase (“a television…Nigeria”) that describes it.
Choice A is incorrect because the comma after “Lagos” doesn’t match the semicolon used later in the series to separate the second item (“A Kind…Nigeria”) from the third item (“and…autobiography”). Choice C is incorrect because the comma after “Lagos” doesn’t match the semicolon used later in the series to separate the second item (“A Kind…Nigeria”) from the third item (“and…autobiography”). Additionally, a colon can’t be used in this way to separate the title “A Kind of Marriage” from the supplementary phrase (“a television…Nigeria”) that describes it. Choice D is incorrect because it fails to use appropriate punctuation to separate the title “A Kind of Marriage” from the supplementary phrase (“a television…Nigeria”) that describes it.

Which choice completes the text so that it conforms to the conventions of Standard English?’, “image”:”, “answer”: [ [‘A. equations, though:’, “true”], [‘B. equations, though,’, “false”], [‘C. equations. Though,’, “false”], [‘D. equations though’, “false”], ], ‘explanation’: ‘Correct Answer: A
Choice A is the best answer. The convention being tested is the use of punctuation to mark boundaries between supplements and clauses. The comma after “equations” is used to separate the independent clause (“Hopper’s… equation”) from the supplementary adverb phrase “though.” The colon after “though” is used to mark the boundary between the clause ending with “though” and the following clause (“as…age”). A colon used in this way introduces information that illustrates or explains information that has come before it. In this case, the colon after “though” introduces the following explanation of how Hopper’s subsequent career would involve more than just solving quations: she would become a pioneering computer programmer.
Choice B is incorrect because it results in a comma splice. A comma can’t be used in this way to join two independent clauses (“Hopper’s…though” and “as…age”) such as these.
Choice C is incorrect because it results in an illogical sequence of sentences. Placing the period after “equations” and beginning the next sentence with “Though” illogically suggests that the following information (that Hopper would help usher in the digital age) is contrary to the information in the previous sentence (Hopper’s subsequent career would involve more than just solving equations). Instead, the information that follows supports the information from the previous sentence by explaining how her work and influence extended beyond solely solving equations.
Choice D is incorrect because it results in a run-on sentence. The two independent clauses (“Hopper’s…though” and “as…age”) are fused without punctuation.

Choice D is the best answer. The convention being tested is punctuation between a supplementary phrase and a main clause. This choice correctly uses a comma to mark the boundary between the supplementary phrase (“A conceptual artist…world”), which describes Mary Ping, and the main clause (“Mary…America”).
Choice A is incorrect because it fails to mark the boundary between the supplementary phrase (“A conceptual artist…world”) and the main clause (“Mary…America”) with appropriate punctuation.
Choice B is incorrect because a colon can’t be used in this way to join the supplementary phrase (“A conceptual artist…world”) and the main clause (“Mary…America”). In this context, the colon incorrectly suggests that the information in the supplementary phrase is an explanation or amplification of the information in the main clause (Mary Ping being chosen to curate the exhibition), which isn’t the case.
Choice C is incorrect because a semicolon can’t be used in this way to join the supplementary phrase (“A conceptual artist…world”) and the main clause (“Mary…America”). Semicolons are conventionally used to separate two main clauses or to separate items in a complex series.

Choice B is the best answer. The convention being tested is the use and punctuation of an integrated relative clause. This choice correctly uses the relative pronoun “that” and no punctuation to create an integrated relative clause that provides essential information about the noun phrase (“a book packaging company”) that it modifies.
Choice A is incorrect because it doesn’t use a relative pronoun to link the verb phrase beginning with “specializes” to the noun phrase that it modifies (“a book packaging company”).
Choice C is incorrect because it doesn’t use a relative pronoun to link the verb phrase beginning with “specializes” to the noun phrase that it modifies (“a book packaging company”).

She’, “true”], ], ‘explanation’: ‘Correct Answer: D Choice D is the best answer. It appropriately uses a period to mark the end of one independent clause (“In 2000… settings”) and the start of another (“She founded…professionals”). Choice A is incorrect. This choice results in a run-on sentence error. Both the clause before the blank (“In 2000… settings”) and the clause after the blank (“she…professionals”) are independent clauses, so they need to be separated by punctuation. Choice B is incorrect. This choice results in a comma splice error. It incorrectly joins two independent clauses with just a comma. Linking two independent clauses with a comma also requires the use of a coordinating conjunction (like for, and, nor, but, or, yet, or so).
Choice C is incorrect. This choice results in a run-on sentence, an error caused when two independent clauses are joined without punctuation or appropriate conjunctions. Since both the clause before the blank (“In 2000…settings”) and the clause after the blank (“she… professionals”) are independent, a comma would be required in addition to the coordinating conjunction “and.”
