Given scientific fact as input, generate the question from this fact such that it can be answered from the input.

Example Input: A bow wake is created when the wave source moves faster than the wave propagation speed.
Example Output: What is created when the wave source moves faster than the wave propagation speed?

Example Input: Particle accelerators can nuclear fusion in stars be simulated.
Example Output: How can nuclear fusion in stars be simulated?

Example Input: Zeroes that show only where the decimal point falls are not significant.
Example Output:
