Question

Science has given humans many amazing devices and useful bits of knowledge. We know so much about our bodies and how to stay healthy, for example. We also know how to make machines and devices that make life easy for us. Scientists dedicate their lives to knowledge, but even with a lifetime commitment, sometimes scientists fail to find all the answers. One mystery that still remains unsolved is why we yawn—what makes us yawn and what purpose it serves.

Which line shows the main idea of the paragraph?
