Answer:
The statement that introduces a new counterclaim to the author's position is letter <u>D) The use of solar energy is especially limited in areas that do not get regular sunlight.</u>
Explanation:
A counterclaim means to rebuff a previous claim about something.
If a person makes a claim to something, usually he bring supporting evidence to validate his claim. Therefore, <u>mentioning the contrary opinion to his own opinion is his counterclaim.</u>
From the essay, the author is defending the use of solar energy because he feels that the energy is clean and renewable unlike most other sources of energy.
Therefore, the statement that makes a counterclaim to the author's opinion that solar energy is clean and renewable is that <u>the use of solar energy is especially limited in areas that do not get regular sunlight.</u>
When looking at what the subject does in a sentence, you are looking at the action. A sentence consists of two basic parts: who/what is doing what. The cat (who/what) chased the mouse (did what). The subject is the who/what part of the sentence, and the verb is the action of the sentence. Consider the following sentence: He ran quickly. A pronoun is a word that renames the noun ("he" rather than "Jim" or some other proper name). And an adverb modifies a verb ("quickly" modifies "ran").
