Question

Science Mysteries: Why Do People Yawn?

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 word from the first paragraph presents the author's view of scientists?
Yawn
Fight
Dedicate
Believe

Answer 1

I think it's dedicate. He puts the scientists in a good light even though they didn't find the answer to the mystery. Dedicate has a good connotation and it's probably the best answer.

Answer 2

I believe the word that presents the author's view is indeed "dedicate".

Step-by-step explanation:

When the author of the passage says, "Scientists dedicate their lives to knowledge," he is conveying a positive idea about scientists. Dedication is associated with commitment, discipline, which implies scientists are hard-working in their purposes. The author, even though saying scientists have failed when it comes to finding out why we yawn, is nevertheless presenting the positive image he has of scientists by using the word "dedicate".
