The sentence emphasizes a difference between C-type and S-type asteroids, noting that C-type asteroids are mainly composed of carbon, while S-type asteroids are mainly composed of silicate minerals. </p><p>Choice A is incorrect. The sentence states that C-type and S-type are two types of asteroids, but it doesn’t emphasize a difference between them. Choice B is incorrect because it doesn’t directly mention C-type or S-type asteroids.&nbsp;Choice C is incorrect. While the sentence mentions that 17 percent of known asteroids are S-type asteroids, it doesn’t identify the percentage of asteroids that are C-type. Therefore, the sentence doesn’t emphasize a difference between the two types. </p>","correct_answer":["D"],"has_media":false,"has_mathml":false,"has_table":false,"source_created_at":"2023-08-02T20:25:59.351000+00:00","source_updated_at":"2023-08-02T20:25:59.351000+00:00","options":[{"label":"A","content_html":"<p>Planetary scientists classify asteroids into types, two of which are the C-type and the S-type.</p>","ord":0},{"label":"B","content_html":"<p>Planetary scientists consider an asteroid’s composition (such as whether the asteroid is composed mainly of silicate minerals or carbon) when classifying it.</p>","ord":1},{"label":"C","content_html":"<p>Roughly 17 percent of known asteroids are classified as S-type asteroids; another percentage is classified as C-type asteroids.&nbsp;</p>","ord":2},{"label":"D","content_html":"<p>C-type asteroids are mainly composed of carbon, whereas S-type asteroids are primarily made up of silicate minerals.</p>","ord":3}],"attribution":{"source_id":"cb_question_bank","source_name":"College Board digital SAT question bank (community dump)","rights_holder":"College Board","canonical_url":"https://satsuitequestionbank.collegeboard.org/","retrieved_from":"https://raw.githubusercontent.com/mdn522/sat-question-bank/main/data/cb-digital-questions.json","attribution":"SAT practice questions © College Board, from the official SAT Suite Question Bank.
