Final Answer:
Unless P swims immediately after T, J swims immediately after S. The statement is true.
Step-by-step explanation:
The statement is a conditional rule describing a sequence of events. It asserts that if P does not swim immediately after T, then J must swim immediately after S. In other words, the sequence either follows the pattern P → T → J or S → J. The use of "unless" introduces a condition that modifies the sequence. If P comes after T, then J must follow S. If P does not follow T, then the sequence shifts to S followed by J. The statement is logically structured, defining a relationship between the swimming order of P, T, J, and S.
The statement is true.
