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

Example Input: Passage: Neutralization reactions between an acid and a base yield a salt and water. In some cases, this results in a completely neutral solution. However, some salts are weakly acidic or basic. How can we tell whether a given salt will act as an acid or base? Looking at the relative strengths of the acid and base that were used to form the salt can give us information on the acid-base properties of the resulting solution. Answer: neutralization
Example Output: What kind of reactions between an acid and a base yield a salt and water?

Example Input: Passage: By losing an electron, the sodium atom becomes a sodium ion. It now has one less electron than protons, giving it a charge of +1. Positive ions such as sodium are given the same name as the element. The chemical symbol has a plus sign to distinguish the ion from an atom of the element. The symbol for a sodium ion is Na + . Answer: becomes sodium ion
Example Output: What happens when a sodium atom loses an electron?

Example Input: Passage: Angiosperms , or flowering seed plants, form seeds in ovaries. As the seeds develop, the ovaries may develop into fruits. Flowers attract pollinators, and fruits encourage animals to disperse the seeds. Answer: angiosperms
Example Output:
What is the term for flowering seed plants?
