A research question should answer this " do i know the field and its literature well" <span />
Answer:
B
Explanation:
Who and whose (which is wrong for a couple of reasons) refer to people. So neither of those 2 can be the answer.
Which and that are all that is left.
The usage is very close. Which, I think, is the correct answer. It usually begins a clause that adds more information to the noun (usually) that it modifies. In this case, the clause modifies mammal and tells it that is unique in that it can fly.
That is normally a pronoun that oddly modifies again usually a specific noun. You are not talking about a bat that lives in your back yard and that you have named. Bats in general are the only mammals that fly.
I still would use which.
The information you need to know regarding daytime sits is provided here.
No matter what you do, spending a lot of time sitting up increases your risk of illness and early mortality. Regardless of how often a person exercises, the amount of time they spend sitting down during the day is associated to a higher risk of developing heart disease, diabetes, cancer, and mortality.
The amount of time a person spends sitting during the day is associated with an increased risk of heart disease, diabetes, cancer, and mortality, even if they regularly exercise.
Overseeing the experiment was Dr. David Alter, a senior scientist at the Toronto Rehabilitation Institute. He said that more than half of the average person's day is spent sitting, watching television, or using a computer.
