You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.

Example Input: Nobody really know's the exact date, but Historians suspect it was sometime in the Spring of the year.
Example Output: The date of jesus's birth?

Example Input: A cloud compsition is primarlly just billions of drops of water or ice. When such a cloud formation has an influx of water/ice, ie it's mass increases to include more water/ice, light finds it hard to pass through the mass, thus making it darker for us to see.

In a normal cloud, light can pass through the water/ice within the cloud and we see it as a distorted white/bluish/greyish/greenish hue. But when the cloud is too thick with water/ice, the light doesn't pass through so easily and we see a darker spectrum.
Example Output: why do clouds turn dark when its about to rain?

Example Input: It is the (secant(x))^2; or you could write it as (cos(x))^(-2) or 1/(cos(x))^2.

But basically the secant squared is the most elegant answer.
Example Output:
What is the derivative of tangent?
