vanishes when the price is set at 25 & equals the square root of the price in excess
of this threshold price. Then the equilibrium at which the supply coincides with the

He greatest chance for the existence of extraterrestrial life is on a planet beyond our
solar system. This is b?coz the Milky Way galaxy alone contains 100 billion other
suns, many of which could be accompanied by planets similar enough to make them
suitable abodes of life.
The argument above assumes which of following?

those on earth
b. life cannot exist on other planets in solar system
c. if the appropriate physical conditions exist, life is an inevitable consequence
d. more than one of the suns in the galaxy is accompanied by an earth like planet
e. it is likely that life on another plane would require conditions similar to those on
