The swimmers worked hard on the synchronization of their water ballet.

A. having movement precede each sound

B. the ability to withstand cold

C. having sound happen at the same time as action

D. having mechanical motion in the performance

Question 1: D. If something is cavernous, that means that it has a large cavity in it. However, according to the context in the question you posted, the best answer would be 'a large and dark space.'

Question 2: C. A paradox is something that contradicts itself. For example, if I travelled back in time and killed my mother before she met my father, she would never give birth to me. However, that would mean that I would never have an opportunity to go back in time and kill my mother, because I wouldn't exist. So, my mother would be alive, which means I would be alive, which means I could travel back in time to kill her, which means she would be dead - and on and on.

Question 3: I'm not sure about the answer for this one. Synchronization is harmony, or movement at the same time; for example, I want to achieve synchronization in my cheering routine with the rest of my teammates - this means that we would perform the cheering routine at the same time, in harmony with each other. The answer is probably C or D.
