review paragraph 3.
3 if a fish has parasites and wants to be cleaned, it looks for a brightly - colored cleaner shrimp waiting on a rock. when the fish swims up to the rock, the cleaner shrimp does a strange dance. the shrimp rocks its body from side to side, and it waves its front legs in the air as if to say, \fish cleaning service! come right in!\ this dance sends a signal to the fish that the shrimp is hungry and willing to clean the parasites off the fish. the fish then changes its color from light to dark. this color change provides a signal to the shrimp that the fish wants to be cleaned.

based on the text, what are two things cleaner shrimp do to show that they are hungry?

• they change colors for the fish.
• they wave their front legs.
• they rock back and forth.

Explanation:

To solve this, we analyze the text: "The shrimp rocks its body from side to side, and it waves its front legs in the air as if to say, 'Fish Cleaning Service! Come right in!' This dance sends a signal to the fish that the shrimp is hungry...". "They change colors for the fish" is what the fish does, not the shrimp. "They jump up and down on the fish" is not mentioned. So the correct actions of the shrimp to show hunger are waving front legs and rocking back and forth.

Answer:

B. They wave their front legs, C. They rock back and forth
