In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.

Ex Input:
Nuclear fusion powers a star for most of its life. Initially the energy is generated by the fusion of hydrogen atoms at the core of the main-sequence star. Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. This process causes the star to gradually grow in size, passing through the subgiant stage until it reaches the red giant phase. Stars with at least half the mass of the Sun can also begin to generate energy through the fusion of helium at their core, whereas more-massive stars can fuse heavier elements along a series of concentric shells. Once a star like the Sun has exhausted its nuclear fuel, its core collapses into a dense white dwarf and the outer layers are expelled as a planetary nebula. Stars with around ten or more times the mass of the Sun can explode in a supernova as their inert iron cores collapse into an extremely dense neutron star or black hole. Although the universe is not old enough for any of the smallest red dwarfs to have reached the end of their lives, stellar models suggest they will slowly become brighter and hotter before running out of hydrogen fuel and becoming low-mass white dwarfs.

Ex Output:
what characteristic of helium makes it a major constituent of the pulsating star mechanism


Ex Input:
Ethical egoism is the normative ethical position that moral agents ought to do what is in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest. Ethical egoism also differs from rational egoism, which holds that it is rational to act in one's self-interest. Ethical egoism holds, therefore, that actions whose consequences will benefit the doer can be considered ethical in this sense.

Ex Output:
how does egoism define what is morally right


Ex Input:
As its members wrote just a handful of songs on the albums, most songs Three Dog Night recorded were written by outside songwriters. Notable hits by outside writers include Harry Nilsson's 'One' (US #5), the Gerome Ragni-James Rado-Galt MacDermot composition 'Easy to Be Hard' (US #4) from the musical Hair, Laura Nyro's 'Eli's Comin'' (US #10), Randy Newman's 'Mama Told Me Not to Come' (US #1), Paul Williams' 'Out in the Country' (US #15), 'The Family Of Man' (US #12), and 'An Old Fashioned Love Song' (US #4), Hoyt Axton's 'Joy to the World' (US #1) and 'Never Been to Spain' (US #5), Arkin & Robinson's 'Black and White' (US #1), Argent's Russ Ballard's 'Liar' (US #7), Elton John and Bernie Taupin's 'Lady Samantha' and 'Your Song', Daniel Moore's 'Shambala' (#3), Leo Sayer's 'The Show Must Go On' (US #4), John Hiatt's 'Sure As I'm Sittin' Here' (US #16), and Bush's 'I Can Hear You Calling'.

Ex Output:

did three dog night write their own songs
