Is the lifetime of a massive star shorter or longer than a star like the sun? why?

If it have a higher temperature and position in the spectrum chart (White, White-Blue, Blue) then it would be longer.

If it is like a Red Giant, then it would be shorter.

Hope this helps!

explanation:

1. it was caused by feudalism

2. charlemagne used christianity as a major cornerstone for his rule. cloisters were built all over the empire to act as centers for the (re)population of the vast european wilderness.

3. the europeans feared the next raid every time chetak

i'm not so sure about #6. but i hope i you with the first 3.
