Its a wing

fish use fins to swim in the water

birds use ____ to fly in the air

so, what do you think?

To find the missing word that completes the part/whole relationship, you need to identify the relationship between the given words and then apply that relationship to the second part of the sentence.

In the first part of the sentence, "A fin is to a fish," we see that a fin is a specific part of a fish. So, we are looking for a word that is a part of a bird.

In this case, the missing word that completes the relationship is "wing". Just as a fin is a part of a fish, a wing is a part of a bird.

Therefore, the completed sentence would be: "A fin is to a fish as a wing is to a bird."
