A question I can't understand on my Cloze test the question sentence is; The brain-cooling theory does not wonder a bigger mystery about yawning, namely, _____________humans yawn when they see someone can do it. and I should fill a blank up. examples are A) show B) reason C) the D) why. I selected (D) why, but, the correct answer is (B). when I studied about relative adverb, my teacher said reason and why can substitute each other. so I confused a little. could somebody explain about that clearly?

Is this the actual sentence?  This sentence is not correct...

 

The brain-cooling theory does not wonder a bigger mystery about yawning, namely, _____________humans yawn when they see someone can do it.

 

"wonder" is not appropriate in this context...

Explain, hypothesize, encompass would work, but "wonder" does not.

Also, it should be "someone else do it" not "someone can do it"

 

To answer your question:  (D) is the correct answer. (B) is wrong.

 

"The reason" and "why" are normally interchangeable.  "reason" is wrong.

 

why humans yawn when they see someone else do it. (correct)

the reason humans yawn when they see someone else do it. (correct)

reason humans yawn when they see someone else do it. (wrong)
