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.

Input: Consider 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.

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


Input: Consider Input: The Kingdom of God Is Within You (Russian: Царство Божие внутри вас (Tsarstvo Bozhiye vnutri vas)) is a non-fiction book written by Leo Tolstoy. A philosophical treatise, the book was first published in Germany in 1894 after being banned in his home country of Russia.

Output: tolstoy books the kingdom of god is within you


Input: Consider Input: A person born on February 29 may be called a 'leapling', a 'leaper', or a 'leap-year baby'. In non-leap years, some leaplings celebrate their birthday on either February 28 or March 1, while others only observe birthdays on the authentic intercalary date, February 29.


Output: when is your birthday if you were born on february 29
