Answer 1

5... yes, I can answer 5 of those questions

Answer 2

The structure is very cool... What you neglected to address, however, was the fundamental difference between environment. A wood floor's ambiguous and impersonal to the foot, sock or no sock. But who's going to wear socks in a bathroom? Who stays barefoot in bed? Who can eternally choose between two basic needs of the foot? This is a deep societal issue! You cannot generalize about such things! Your question is akin to comparing preferences between Dove and Hershey chocolate--IT CANNOT BE DONE! THIS IS BLASPHEMY!!! Come and ask this again when you have gained a sense of propriety concerning such matters. I command it. So let it be written. So let it be done.

Answer 3

I can't say I can answer any of them, but I can tell you that 9b+6c=X
X=how many burgers to put on the grill.
I don't understand that crap you wrote, but I did stay at a holiday inn express last night.

Answer 4

I can answer all 12, but I am afraid I cannot vouch for the correctness of the answers.

Might I suggest you do your homework?

Answer 5

None, its 3 am and I'm to tired to read them all

Answer 6

i can answer 11 of them right off hand still trying to figure out the other one.

Answer 7

None of them I am not a chemist.

Answer 8

i can give all 12 if i m able to understand

Answer 9

I can answer all of them. Not necessarily correctly.

Answer 10

Are you trying to challenge people to do your homework?
