Question: I was googling the reason for why it's called "shotgun" to ride beside the driver when it suddenly hit me - why on Earth is the firearm called "shotgun"?! Is there any other kind of a gun than one used for shooting?! Why is it called "shotgun" instead of just a "gun" or a more technical term (9-gauge, barrel gun etc.)? 
Answer: There are other things that shoot 'shot'. Cannons fired grapeshot as an effective way to deal with infantry. This makes a 'shotgun' just a gun that shoots shot instead of a cannon that does so. This clever naming scheme is also visible for 'rifles' which are simply guns with barrels that have been rifled.
answer:
no

Question: I am developing some software where users are assigned tasks. They will see a date and time for when they were assigned to the task, but if they were later removed from the task, there will be a date and time for that also. 01/02/14 - Assigned 03/02/14 - Unassigned I'm pretty sure unassigned isn't correct. I suppose the task itself could be in a state of being unassigned, but the user wasn't "unassigned" from it. Notes: I don't want to use the word "removed", as I don't think it conveys the correct meaning and also sounds too harsh. I would like to avoid using a word your average person would never have heard of, as this isn't very user-friendly from a software point of view. 
Answer: "revoked", "withdrawn", "retracted", or simply "reassigned".
answer:
yes


question:
Question: A friend posed the following word puzzle to me: Can you think of a sentence that keeps the same meaning whether you use "it's" or "its"? He asserted that this puzzle does in fact have a solution. However, it has me completely stumped. I tried to solve an easier problem, to find a sentence which is still grammatical if you change an "its" to "it's", but all I could come up with is examples like "It's light!" (which is, strictly, more of a sentence fragment). What is the solution to the word puzzle? Or, is there some way I can "prove" that the puzzle should have no solution? 
Answer: 'It's just what its supposed to be.' or 'Its just what it's supposed to be.'.
answer:

no
