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

Example Input: Passage: An autoimmune disease is a disease in which the immune system attacks the body's own cells. Why this happens is not known for certain, but a combination of genetic and environmental factors are likely to be responsible. Type 1 diabetes is an example of an autoimmune disease. In this case, the immune system attacks cells of the pancreas. Two other examples are multiple sclerosis and rheumatoid arthritis. Answer: autoimmune
Example Output: What term describes a disease in which the immune system attacks the body's own cells?

Example Input: Passage: Now that you have learned that the cell membrane surrounds all cells, you can dive inside of a prototypical human cell to learn about its internal components and their functions. All living cells in multicellular organisms contain an internal cytoplasmic compartment, and a nucleus within the cytoplasm. Cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for biochemical reactions. Eukaryotic cells, including all animal cells, also contain various cellular organelles. An organelle ("little organ") is one of several different types of membrane-enclosed bodies in the cell, each performing a unique function. Just as the various bodily organs work together in harmony to perform all of a human's functions, the many different cellular organelles work together to keep the cell healthy and performing all of its important functions. The organelles and cytosol, taken together, compose the cell's cytoplasm. The nucleus is a cell's central organelle, which contains the cell's DNA (Figure 3.13). Answer: biochemical reactions
Example Output: All living cells in multicellular organisms contain an internal cytoplasmic compartment, and a nucleus within the cytoplasm. cytosol, the jelly-like substance within the cell, provides the fluid medium necessary for this?

Example Input: Passage: Earth and the other planets in the solar system make elliptical orbits around the Sun. The ellipses in this image are highly exaggerated. Answer: elliptical orbits
Example Output:
What do earth and the other planets in the solar system make around the sun?
