Explain how the answer you chose conveys the text's central idea. Scientists guess that the trap might close using some electrical impulses and pressure changes.

Complete question statement is;

Which sentence from the paragraph best shows the text's central idea? A"One of the most mysterious things about the Venus flytrap is that scientists still don't understand how the trap closes."B"The flytrap does not have the muscles, tendons, or nervous system necessary for movement."C"Scientists guess that the trap might close using some electrical impulses and pressure changes."D"It should be no mystery, however, why this unusual plant has captured the imaginations of so many people."

Explanation:

The missing paragraph is stated below;

One of the most mysterious things about the Venus flytrap is that scientists still don't understand how the trap closes. The flytrap does not have the muscles, tendons, or nervous system necessary for movement. Scientists guess that the trap might close using some electrical impulses and pressure changes. The longer they study the Venus flytrap, the more likely scientists are to discover how it functions. It should be no mystery, however, why this unusual plant has captured the imaginations of so many people.

Hence reading the above paragraph, we can find that there is no definite answers to the methodology of Venus flytrap trap closing but scientists research lead them to think that it was due to some electrical impulses and pressure changes. Hence option C is correct
