In an experiment, biologists repeatedly shone a bright light into a tank containing a sea snail and simultaneously shook the tank. The snail invariably responded by tensing its muscular “foot,” a typical reaction in sea snails to ocean turbulence. After several repetitions of this procedure, the snail tensed its “foot” whenever the biologists shone the light into its tank, even when the tank was not simultaneously shaken. Therefore, the snail must have learned to associate the shining of the bright light with the shaking of the tank.
Which one of the following is an assumption required by the argument?
(A) All sea snails react to ocean turbulence in the same way as the sea snail in the experiment did.
(B) Sea snails are not ordinarily exposed to bright lights such as the one used in the biologists’ experiment.
(C) The sea snail used in the experiment did not differ significantly from other members of its species in its reaction to external stimuli.
(D) The appearance of a bright light alone would ordinarily not result in the sea snail’s tensing its “foot.”
(E) Tensing of the muscular “foot” in sea snails is an instinctual rather than a learned response to ocean turbulence.

already know about that, but cant support conclusion that sea snail learned from external stimuli

D is correct IMO
(A) All sea snails react to ocean turbulence in the same way as the sea snail in the experiment did.
Irrelevant
(B) Sea snails are not ordinarily exposed to bright lights such as the one used in the biologists’ experiment.
Does not matter. Even if exposed but not put through shaking. Experiment is not completed.
(C) The sea snail used in the experiment did not differ significantly from other members of its species in its reaction to external stimuli.
Out of scope. Argument mentions only the subject scope.
(D) The appearance of a bright light alone would ordinarily not result in the sea snail’s tensing its “foot.”
Yes, if light alone is responsible. Hypothesis fails.
(E) Tensing of the muscular “foot” in sea snails is an instinctual rather than a learned response to ocean turbulence.
Irrelevant, Type of response is not relevant.
