Which of the following situations might require voters to hold a special election?
a.
a citizen announces that he or she is interested in running for office.
b.
a regularly scheduled election day is approaching.
c.
a state governor resigns from office partway through his or her term.
d.
a president reaches the end of his or her term.

I believe its c. Im not sure why but I got it right on my tests

The correct answer is C) A state governor resigns from office partway through his or her term.

The situation that might require voters to hold a special election is "A state governor resigns from office partway through his or her term."

Another situation that might require a special election is when a Senator resigns, dies or cannot end his/her term for whatever reason. It is a different case, depending on the State. But it is the governor who issues a writ for a special election. The winner of a special election does not last the six years, just the remainder of the time.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
