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

Example Input: Passage: Hormones Hormones are molecular signals that help regulate a number of biochemical processes. Single amino acids and short protein chains are very common types of hormones. For example, insulin is a protein hormone that regulates the amount of glucose present in the bloodstream. Answer: hormones
Example Output: What do you call the type of molecular signals that include insulin and that help regulate a number of biochemical processes?

Example Input: Passage: Regulation of transcription in prokaryotes typically involves operons. An operon is a region of DNA that consists of one or more genes that encode the proteins needed for a specific function. The operon also includes a promoter and an operator. The operator is a region of the operon where regulatory proteins bind. It is located near the promoter and helps regulate transcription of the operon genes. Answer: operon
Example Output: Which region of dna consists of one or more genes that encode the proteins needed for a specific function?

Example Input: Passage: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points. You can see the melting and boiling points of several different ionic compounds in the Table below . To appreciate how high they are, consider that the melting and boiling points of water, which is not an ionic compound, are 0C and 100C, respectively. Answer: one hundred degrees
Example Output:
In celsius, what is the boiling point of water?
