Answer: D) contains few adjectives and adverbs but many strong verbs and concrete nouns.
Explanation: In the given excerpt from Hemingway's "A Farewell to Arms" we can see a clear example of Hemingway's typical style of writing, that is characterized by the use of many strong verbs and concrete nouns, but using just few (the necessary) adjectives and adverbs. In the excerpt he uses strong verbs like "listen" and "realize" and we can also see that the sentences are short with little modifiers.
The verb "looks" would be in this case a linking verb, since it is helping the reader understand the point of view of the observer. The weather itself is of course not "looking" anywhere.
