This question is asking for could be true EXCEPT, so we are looking for a must be false answer.
A is allowed: 1(T) 2 (M, Y, W) 3 (T) 4 (M)
E is not allowed: since WY has to be in 1 if another Y is in 3. But that would put two W next to each other in both 1 and 2 : 1 (Y, W) 2 (W) 3 (Y)作者: taoransk 时间: 2010-12-4 15:40
Thx mate. I'd forgotten about difference between grants in each quater and total number of grants -.-
Only concerned about 2 grants each, but overlooked the possibility on decent quater can have more than 2 grants, as long as they are following rules above ...
