  4. Seahorse fishermen have spoken out against the biologists.

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to carefully read and analyze the information provided. The statement that must be true according to the given information is option B, "One way to increase seahorse populations is to ban the fishing of seahorses." This conclusion can be drawn from the information that seahorse populations have declined everywhere that seahorses are fished, and that biologists met to discuss what might be done to reverse this trend. If seahorse populations have decreased by 50% in the past five years, it suggests that current methods of fishing and seahorse conservation are not working. Therefore, it is reasonable to assume that banning the fishing of seahorses could help to increase populations. Option A is incorrect because the information does not provide evidence that seahorses are likely to become extinct within five years. Option C is incorrect because the information does not indicate that biologists from all over the world are working to save the seahorses. Option D is incorrect because the information does not mention the opinions of seahorse fishermen.

The Answer is: B
