Example Input: Passage: Saturated fatty acids have only single bonds between carbon atoms. As a result, the carbon atoms are bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogens. Saturated fatty acids are found in fats. Answer: saturated
Example Output: Carbon atoms are bonded to as many hydrogen atoms as possible in what type of fatty acids?

Example Input: Passage: The hemisphere that is tilted away from the Sun is cooler because it receives less direct rays. As Earth orbits the Sun, the Northern Hemisphere goes from winter to spring, then summer and fall. The Southern Hemisphere does the opposite from summer to fall to winter to spring. When it is winter in the Northern hemisphere, it is summer in the Southern hemisphere, and vice versa. Answer: direct rays
Example Output:
The hemisphere that is tilted away from the sun is cooler because it receives less what?
