You can predict
Hi Uri,
No you cannot simply know how many questions there are for a passage. However, you can predict closely, as no of questions is directly proportional to the length of the passage.
Thanks,

Very simple formula
You can use M1D1W2 = M2D2W1.
So, here its M1D1 = M2D2 => 10*16 = 8*x
x = 20.
Very simple........
