1. If either the sea turtle population continues to decrease or rescue efforts
are commenced to save the sea turtle from extinction, then nesting sanctuaries
will be created and the indiscriminate slaughter of these animals will be
halted. If either nesting sanctuaries are created or poachers are arrested,
then if the indiscriminate slaughter of these animals is halted, then the sea
turtle population will not continue to decrease. Therefore, the sea turtle
population will not continue to decrease. (C, R, N, I, P)



2. Either deposits should be required on beer and soft drink containers, or

deposits should be required on soft drink containers. (B, S, H, C, P)
