TASK DEFINITION: Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.
PROBLEM: Question: As in "the timeslot given to completing the task". Would also be interested to hear if there's different usages for different scenarios. 
Answer: Both timeslot and time slot are acceptable. You will find an equal amount of dictionaries containing either. Regarding the hyphenated version, there's been a general trend to move away from hyphenated compound words over the past 40 years. A common, historical pattern is that two words say, time slot will be joined by a hyphen for a time time-slot and then be joined into one word timeslot. English is moving away from this and joining languages like German, where words are advantageously and immediately linked to one another.

SOLUTION: no

PROBLEM: Question: So I have seen usages of "Your will be done" in the context when some higher authority is issuing orders but shouldn't it be "Your will will be done"? it makes more semantic sense than the former. 
Answer: Will and will are two different, unrelated words. The fact the spelling is the same has no relevance to grammar or semantics.

SOLUTION: no

PROBLEM: Question: "Polarizes" is not the right word for this. If you can imagine a group of people being strictly divided in opinion, the ideological line which divided them would be the thing I am trying to generically name. I'm looking for a specific word that I know I've seen before but can't remember. I've googled this but have not been able to find the right word. This is the best definition I can provide. An (poor) example is how a stance on taxes divides people into Democrats and Republicans 
Answer: It sounds like you are looking for the word issue: whether taxes should be equally applied to rich and poor, or scaled, is the issue that divides Democrats and Republicans.

SOLUTION:
no
