A main-sequence star twice as massive as the Sun would last___

about half as long as the Sun
much less than half as long as the Sun
about twice as long as the Sun
much longer than twice as long as the Sun
 
Less than the life our sun has
.'
The larger the mass the more energy it uses
.
Kind of like which motor uses more gas when it is idling in the drive way
.'
A 4 cylinder or a big V-8
.
With this analogy you can see why a larger one will burn out faster
