Answer:
B. Showed
Step-by-step explanation:
We can use context clues to predict or figure out the meaning of a word.
A. Praised won't make any sense, because you wouldn't praise or compliment someone for acting immorally foolish. X
B. Showed makes sense because he showed portraits of the gods acting foolish. ☆
C. Prayed to doesn't make sense because you don't pray to the failings of gods acting foolish. X
D. Warned about is not a good term because he didn't seem to warn them or give them a punishment, all he showed was a portrait of the gods acting foolish.
Now we figured out the term depicted by using context clues, and substituting each word in order to see if it will make sense with the sentence.
