Given a scientific passage and an answer, generate a question for the given answer.

Ex Input:
Passage: Inhaling is an active movement that results from the contraction of a muscle called the diaphragm. The diaphragm is large, sheet-like muscle below the lungs (see Figure below ). When the diaphragm contracts, the ribcage expands and the contents of the abdomen move downward. This results in a larger chest volume, which decreases air pressure inside the lungs. With lower air pressure inside than outside the lungs, air rushes into the lungs. When the diaphragm relaxes, the opposite events occur. The volume of the chest cavity decreases, air pressure inside the lungs increases, and air flows out of the lungs, like air rushing out of a balloon. Answer: diaphragm

Ex Output:
Contraction of what large, sheet-like muscle results in inhalation?

Ex Input:
Passage: During meiosis, homologous chromosomes separate and go to different gametes. Thus, the two alleles for each gene also go to different gametes. At the same time, different chromosomes assort independently. As a result, alleles for different genes assort independently as well. In these ways, alleles are shuffled and recombined in each parent's gametes. Answer: during meiosis

Ex Output:
When do homologous chromosomes separate and go to different gametes?

Ex Input:
Passage: All cells, including both plant and animal cells, need energy for processes such as active transport. How do cells obtain the energy they need?. Answer: energy

Ex Output:
All cells need what for processes like active transport?
