参考答案
正确答案：D
解析：Why does the instructor say this:
"We recognize that fire is a natural and revitalizing process that enhances the diversity of the forest. However, we also know that fire has consequences. There may be smoky, hazy skies and patches of blackened forest for a long time after a fire. There's also the risk of a fire becoming too large and threatening inhabited areas."
The instructor's purpose is to give examples of the negative effects of fire. The instructor says ...fire has consequences (negative effects), and then he lists smoky, hazy skies and patches of blackened forest, and the risk of afire becoming too large as examples. (2.3)
