Question

about 70,000 meteorites have been found on earth. although most meteorites are fragments of ______ hundred have been identified as being from the moon or mars. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a asteroids: several b asteroids; several c asteroids, several d asteroids. several

Explanation:

To determine the correct punctuation, we analyze the sentence structure. The first part "About 70,000 meteorites... fragments of asteroids" is a complete thought, and the second part "hundred have been... Moon or Mars" is also a complete sentence. So we need a period to separate the two independent clauses, and the second sentence should start with a capital letter. Option D uses a period after "asteroids" and capitalizes "Several", which conforms to Standard English conventions. Options A and B use colons/semicolons incorrectly here, and Option C uses a comma which is not suitable for separating two independent clauses.

Answer:

D. asteroids. Several
