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

Example Input: Passage: A population is a group of individuals of the same species that live in the same area. The population is the unit of natural selection, adaptation, and microevolution. In ecology, how large a population is and how quickly it is growing are often used as measures of a species' health. Answer: population
Example Output: What term refers to a group of individuals of the same species that live in the same area and is the unit of natural selection, adaptation, and microevolution?

Example Input: Passage: You consist of a great many cells, but like all other organisms, you started life as a single cell. How did you develop from a single cell into an organism with trillions of cells? The answer is cell division. After cells grow to their maximum size, they divide into two new cells. These new cells are small at first, but they grow quickly and eventually divide and produce more new cells. This process keeps repeating in a continuous cycle. Answer: cell division
Example Output: What process allows an individual to develop from a single cell into an organism with trillions of cells?

Example Input: Passage: They will all blend together. The dyes will move through the water until an even distribution is achieved. The process of moving from areas of high amounts to areas of low amounts is called diffusion. Answer: diffusion
Example Output:
The process of moving from areas of high amounts to areas of low amounts is called what?
