Two decades after the Dead Sea Barrier was built, none of

Two decades after the Dead Sea Barrier was built, none of the eight sea slug types indigenous to the Dead Sea was still growing adequately in the Sea on one side of the barrier. Since the barrier reduced the annual range of salinity (percentage of salt) in the Sea on one side of the barrier from 30% to 6%, scientists have hypothesized that sharply rising salinity must be involved in signaling the indigenous types of slugs to begin the growing cycle.


Which of the following statements, if true, would most strengthen the scientists' theory?
Choices
A
The indigenous sea slug types could still grow only on one side of the barrier, where the yearly salinity range remained 30%.

B
Before the barrier was constructed, the Dead Sea overflowed its shores yearly, creating salt licks that became key feeding spots for the indigenous type of sea slug.

C
Before the barrier was built, the lowest recorded salinity of the Dead Sea was 16%, whereas after the barrier was built, the lowest recorded salinity of the Sea has been 25%.

D
Non-indigenous types of sea slug, introduced into the Dead Sea after the barrier’s construction, started competing with the declining indigenous sea slug types for salt.

E
Of the sea slug types indigenous to the Dead Sea, six are not indigenous to any other sea in the Middle East.
