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

Example Input: Passage: Jupiter has lots of moons. As of 2011, we have discovered over 60 natural satellites of Jupiter. Four are big enough and bright enough to be seen from Earth using a pair of binoculars. These four moons were first discovered by Galileo in 1610. They are called the Galilean moons . Figure below shows the four Galilean moons and their sizes relative to Jupiter's Great Red Spot. These moons are named Io, Europa, Ganymede, and Callisto. The Galilean moons are larger than even the biggest dwarf planets, Pluto and Eris. Ganymede is the biggest moon in the solar system. It is even larger than the planet Mercury!. Answer: galileo
Example Output: Who first discovered the moons of jupiter in 1610?

Example Input: Passage: All matter is composed of tiny indivisible particles called atoms. All atoms of an element are identical in mass and chemical properties, whereas atoms of different elements differ in mass and fundamental chemical properties. A chemical compound is a substance that always contains the same atoms in the same ratio. In chemical reactions, atoms from one or more compounds or elements redistribute or rearrange in relation to other atoms to form one or more new compounds. Atoms themselves do not undergo a change of identity in chemical reactions. This last hypothesis suggested that the alchemists' goal of transmuting other elements to gold was impossible, at least through chemical reactions. We now know that Dalton's atomic theory is essentially correct, with four minor modifications:. Answer: chemical properties
Example Output: All matter is composed of tiny indivisible particles called atoms. all atoms of an element are identical in mass and this?

Example Input: Passage: Two important concepts associated with the ecosystem are niche and habitat. Answer: ecosystem
Example Output:
Two important concepts, niche and habitat, are associated with what?
