TASK DEFINITION: Given a scientific passage and an answer, generate a question for the given answer.
PROBLEM: Passage: Minerals are chemical elements that don't come from living things or include the element carbon. Many minerals are needed in the diet for normal functioning of the body. Several minerals that are needed in relatively large amounts are listed in Table below . As you can see from these examples, minerals have a diversity of important functions. Your body can't produce any of the minerals it needs, so you must get them from the food you eat. The table shows good food sources of the minerals. Answer: minerals

SOLUTION: What is the name for elements that neither contain carbon nor come from living things?

PROBLEM: Passage: The Universe contains about a hundred billion galaxies. Answer: about a hundred billion

SOLUTION: Approximately how many galaxies are there in the universe?

PROBLEM: Passage: ♦️ Many industrial processes for preparing compounds use "continuous-flow reactors," which are chemical reaction vessels in which the reactants are mixed and allowed to react as they flow along a tube. The products are removed at a certain distance from the starting point, when the reaction is nearly complete. The key operating parameters in a continuous-flow reactor are temperature, reactor volume, and reactant flow rate. As an industrial chemist, you think you have successfully modified a particular process to produce a higher product yield by substituting one reactant for another. The viscosity of the new reactant is, however, greater than that of the initial reactant. Answer: reactants

SOLUTION:
Continuous-flow reactors are chemical reaction vessels in which the what are mixed and allowed to react as they flow along a tube?
