Reading and Writing · Standard English Conventions · Easy · Answer it here, explanation included.
Obsidian is a kind of volcanic glass formed when lava cools so quickly that the atoms inside it cannot arrange themselves in a crystalline structure. You blank more about obsidian’s structure, which is classified as amorphous, in a later chapter.
Which choice completes the text so that it conforms to the conventions of Standard English?
ExplanationShow
Choice C is the best answer. The convention being tested is the use of verbs to express tense in a sentence. In this choice, the future tense verb “will learn,” used in conjunction with the phrase “in a later chapter,” correctly indicates that “you” (the reader) are going to learn about obsidian’s structure at some point in the future.
Choice A is incorrect because the past perfect verb “had learned” doesn’t indicate that the subject is going to learn about obsidian’s structure in the future. Choice B is incorrect because the past perfect progressive verb “had been learning” doesn’t indicate that the subject is going to learn about obsidian’s structure in the future. Choice D is incorrect because the present perfect verb “have learned” doesn’t indicate that the subject is going to learn about obsidian’s structure in the future.
