The argument states that small fish swimming in schools have a reduced chance of being attacked by a shark because the shark might find something else to attack. The assumption required for this argument is that sharks do not attack entire schools of fish at once, which supports the idea that being in a school reduces the individual fish's chance of being attacked.

Let's evaluate the options:

(A) Sharks live primarily on a diet of small fish.
This may be true, but it does not directly relate to the mechanism by which being in a school reduces the risk of attack.

(B) Sharks do not eat an entire school of fish at one time.
This is a necessary assumption for the argument. If sharks attacked entire schools, being in a school would not reduce the individual fish's chances of being attacked.

(C) The sheer number of fish in a school prevents sharks from attacking.
This suggests a different mechanism (intimidation by numbers) than the one presented in the argument, which focuses on distraction.

(D) Sharks are the main danger to small fish in the open ocean.
While this might be relevant, it is not essential to the argument about how being in a school reduces the chance of attack by a shark.

(E) Small fish are able to sense when they are being spotted by sharks.
This is not related to the argument's focus on the shark's behavior and does not impact the reasoning about schools reducing attack risk.

Correct Answer: (B)
