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

Example Input: Passage: Ribozymes are RNA molecules that catalyze chemical reactions, such as translation. Ribosomes, which are just made out of rRNA (ribosomal RNA) and protein, have been classified as ribozymes , because the rRNA has enzymatic activity. The rRNA is important for the peptidyl transferase activity that bonds amino acids. Briefly, the ribosomes interact with other RNA molecules to make chains of amino acids called polypeptide chains, due to the peptide bond that forms between individual amino acids. Inside the ribosome, three sites participate in the translation process, the A, P and E sites. Translation will be discussed in detail the Protein Synthesis: Translation (Advanced) concept. Answer: chemical reactions
Example Output: Ribozymes are rna molecules that catalyze what?

Example Input: Passage: Avian Respiration Birds have evolved a respiratory system that enables them to fly. Flying is a high-energy process and requires a lot of oxygen. Furthermore, many birds fly in high altitudes where the concentration of oxygen in low. How did birds evolve a respiratory system that is so unique? Decades of research by paleontologists have shown that birds evolved from therapods, meat-eating dinosaurs (Figure 39.14). In fact, fossil evidence shows that meat-eating dinosaurs that lived more than 100 million years ago had a similar flow-through respiratory system with lungs and air sacs. Archaeopteryx and Xiaotingia, for example, were flying dinosaurs and are believed to be early precursors of birds. Answer: oxygen
Example Output: Birds have evolved a respiratory system that enables them to fly. flying is a high-energy process and requires a lot of this?

Example Input: Passage: Electric devices, such as lights and household appliances, change electric current to other forms of energy. For example, an electric stove changes electric current to thermal energy. Other common devices, such as mobile phones and computers, use electric current for another purpose: to encode information. A message encoded this way is called an electronic signal , and the use of electric current for this purpose is called electronics . For an overview of electronics and electronic signals, read the short article at this URL: http://www. bbc. co. uk/scotland/learning/bitesize/standard/physics/electronics/overview_rev1. shtml . Answer: thermal
Example Output:
An electric stove changes electric current to what form of energy?
