Water is to moisten as spade is to dig.

the function of water may be taken to moisten. similarly, a spade may be used to dig. therefore, this "water is to moisten and spade is to dig" is an example of a function analogy, as the functions of both water and spade are being considered. synonym analogies contain synonyms, antonym analogies contain antonyms and description analogies describe one object using the second word.

explanation:

halibut, flounder, tuna, and trout are all fish. so your first answer is 1.) fish. and since fish is edible, your next answer would be 3). edible

to describe those fishes more thoroughly, some of those fishes live in fresh water, and some of the fishes live in salt water, and that is not a thing that they all have in common. the question is asking what is common with all of the fish, so answer choices 2). fresh water and 4). salt water are not right.
