Question

select the linking verb and the predicate noun or predicate adjective.
samoyed dogs, though husky and wolflike, look friendly due to their upward - curving \smiling\ mouths and erect ears.

Explanation:

A linking verb connects the subject to a word that describes or identifies it. In the sentence, "look" functions as a linking verb (a type of copula verb) that links the subject "Samoyed dogs" to the adjective "friendly" which describes the subject. The predicate adjective here is "friendly" as it follows the linking verb and modifies the subject.

Answer:

Linking verb: look; Predicate adjective: friendly
