b. The teacher appeared angry when Dave forgot his homework.
c. What does this hard lesson teach you?
d. We scanned the distant shore for signs of life.

Answer 1

The sentence that contains a predicate adjective is:
B. The teacher appeared angry when Dave forgot his homework.

Predicate Adjective is an adjective that tells something about the subject of the sentence. It appears after a linking verb.

Subject = the teacher
linking verb = appeared 
predicate adjective = angry.
