Marine biologists had hypothesized that lobster kept together in lobster traps eat one another in response to hunger. Periodic checking of lobster traps, however, has revealed instances of lobsters sharing traps together for weeks. Eight lobsters even shared trap together for two months without eating one another. The marine biologistsâ€™ hypothesis, therefore , is clearly wrong.

The argument against the marine biologistsâ€™ hypothesis is based on which one of the following assumptions

A)Lobsters not caught in lobster traps have been observed eating one another

B)Two months is the longest known period during which eight or more lobsters have been trapped together

C)it is unusual to find as many as eight lobsters caught together in one single trap

D)Members of the other marine species sometimes eat their own kind when no other food sources are available

E)Any food that the eight lobsters in the trap might have obtained was not enough to ward off hunger

Picked E as well.

Clealy if they were sufficiently fed, there is no reason to eat one another and thus might not be effective in refuting the hypothesis.
