Answer:
D) When corals are babies floating in the plankton, fish swim with them and protect them from harm.
Explanation:
This is the statement that does not explain how fish and coral relate to one another. It is false that when corals are babies, fish swim with them and protect them. However, the rest of the statements are true. It is true that fish eat predators, and that they also eat seaweed and kelp that could smother the coral. Finally, it is also true that some fish live symbiotically with coral, luring prey for the coral to kill and eat.

Answer:
The correct option is C. Building a well between the two wells that goes deeper into the earth would not stop the water from being polluted .
Explanation:
Even if a well was constructed between the wells B and C, it wouldn't have stopped the contamination of the water. As the oil would still be leaking and it would contaminate the wells.
All of the other options can be used to stop the contamination.
Option A suggests building an impermeable membrane that would stop the oil flow. Hence, the water in the wells will not be contaminated.
Option B suggests not using the water from the wells and using an alternate water supply. The alternate water supply wouldn't be contaminated with oil.
Option D suggests chemically purifying the contaminated water. This can be an effective technique to clean the contaminated water.
