Answer from cs61c-aj (Kevin Li 15855812) for Question 2
Since multilevel convention is that each level of mapping corresponds to more bits on the left so in convention it seems that it would be wise to leave the super page to the far left and the 2nd level page number to the right of it. Also how mapping and translation occurs it seems wise to have the farther bit to the left map to the highest level of page.
(I don't think this is covered in reading... I had to attempt to dig the answer through some websites)
