No i don't know how to explain question 1 3 4 5.

I can answer question 2 the reason is any set of 6 vectors in R5 is linearly dependent, even though some sets of 6 vectors in R5 span R5. To be a basis it must be a linearly independent spanning set, so if it's linearly dependent, it cannot be a basis. But actually I know the answer for all of...

Thanks for reminding. This is my first time to ask question here so sorry about that.

Thanks. I just edited the form of the question and now it should be ok..btw, Can u help me to this question?
