saving sea turtles\nsmall - scale fishing performed with nets is one of the most common fishing methods used around the world. one of the unfortunate side effects of this method is that sea turtles, which are considered threatened, get caught in the nets along with the fish. conservation biologists at the university of exeter in england recently devised a way to prevent these sea turtle deaths, which they tested at a fishery in northern peru. they found that attaching green led lights to the nets warned the turtles away, possibly because the lights made the nets more visible. the number of sea turtle deaths was reduced, but the number of fish caught seemed to remain the same.\nwhat is the main, or central, idea of the passage?\nconservation biologists are researching ways to save the threatened sea turtle population.\none problem with small - catch fishing is that sea turtles get caught along with fish.\nto prevent turtles from becoming caught in fishing nets, conservation biologists attached led lights to the nets.

Answer

Brief Explanations:

The passage first mentions the problem of sea turtles getting caught in fishing nets. Then it focuses on the solution (attaching green LED lights to the nets) devised by conservation biologists to prevent sea turtle deaths. The first option is too general as it just says researching ways. The second option only mentions the problem. The third option includes both the problem (sea turtles getting caught) and the solution (attaching LED lights), which is the main idea.

Answer:

To prevent turtles from becoming caught in fishing nets, conservation biologists attached LED lights to the nets.
