I am a scientist, and this is the type of question that scientists ask.

Five months later the scientists asked parents about their infants' sleep patterns.

This does not mean that a scientist cannot speculate and ask "What if?"

But recently, more scientists have been asking whether something else may be involved.

Many scientists are asking about the future consequences of research.

But now scientists are asking whether there might be a dark side to so much brightness.

It was never a surprise when the young scientist asked the first question at meetings.

A scientist asks me what goes on within a cell, and I tell him.

Philosophers and scientists therefore ask where these experiences come from.

He knew that the scientist would not ask any questions without good reasons for them.
