Answer and Explanation:
As we know, an adjective is a word that modifies a noun or a pronoun by attributing a quality to it. Let's focus on each sentence at a time:
- The monstrous shuttle pitched forward slightly, then rocked back. --> <u>According to the number in parentheses, we only have one adjective here. In that case, it can only be </u><u>monstrous</u><u>, indicating the quality of the shuttle, its appearance.</u>
- Over seven million pounds of thrust pushed the anxious men upward. --> <u>According to the number in parentheses, we have two adjectives here. Numbers are usually adjectives. In this case, the number we have is </u><u>seven million, </u><u>and it is modifying the noun "pounds". Besides that, </u><u>anxious</u><u> is also an adjective, modifying the noun "men".</u>
<u />
- The solid-rocket booster engines lit, and the shaking roar told the astronauts they were entering outer space. --> <u>Now, we are supposed to have four adjectives in the sentence. The noun "engines" is being modified by two adjectives: first by </u><u>solid-rocket</u><u>, then by </u><u>booster</u><u>. The next adjective is </u><u>shaking</u><u>, modifying the noun "roar". Finally, we have </u><u>outer</u><u>, modifying the noun "space".</u>
