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

Example Input: Passage: Each kind of pigment absorbs specific wavelengths (colors) of light (dashed lines). Sunlight contains many different wavelengths, which you see when they separate into a rainbow. Not all colors of light are used in photosynthesis (solid line). Most plants, algae, and photosynthetic bacteria appear green because they reflect green wavelengths. Their pigments have absorbed the violet-blue and red wavelengths. The amount of photosynthesis depends on the wavelength of light available. Beta-carotene is another type of pigment that absorbs sunlight. Answer: rainbow
Example Output: Sunlight contains many different wavelengths, which you see when they separate into what?

Example Input: Passage: Red litmus paper turns blue when placed in a basic solution. Answer: blue
Example Output: Red litmus paper turns what color when placed in a basic solution?

Example Input: Passage: Amino acids can bond together through peptide bonds to form short chains called peptides or longer chains called polypeptides ( Figure below ). A peptide bond is a covalent bond formed from a condensation reaction between two molecules, causing the release of a molecule of water. This bond usually forms between two amino acids, hence forming a peptide or polypeptide. Peptide bonds between amino acids are formed during the process of translation. Answer: process of translation
Example Output:
When are peptide bonds between amino acids formed?
