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

Input: Consider Input: Passage: Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below , look similar on the outside. They also have the same function. However, wings evolved independently in the two groups of animals. This is apparent when you compare the pattern of bones inside the wings. Answer: analogous

Output: What term is used to describe structures that are similar in unrelated organisms?

Input: Consider Input: Passage: What does sunshine have to do with sleep (other than the sun shining in your eyes and waking you up)? For many people, sleeping problems have to do with an amine that the brain makes called melatonin. This compound affects the sleep-wake cycle and is affected by sunlight. During the winter, the daily cycle of melatonin production may be affected by less sunlight hours. If this cycle is changed, the person may have trouble sleeping. Melatonin supplements are available in pharmacies and health food stores and may be of help for those with sleeping problems. Answer: melatonin

Output: During the winter, production of what amine involved in the sleep-wake cycle may be affected by less sunlight hours?

Input: Consider Input: Passage: The process of getting oxygen into the body and releasing carbon dioxide is called respiration . Sometimes breathing is called respiration, but there is much more to respiration than just breathing. Breathing is only the movement of oxygen into the body and carbon dioxide out of the body. The process of respiration also includes the exchange of oxygen and carbon dioxide between the blood and the cells of the body. Answer: respiration
Output: The process of getting oxygen into the body and releasing carbon dioxide is called?
