(1) The number of individuals who moved out of the room was greater than 5
(2) The number of individuals who moved out of the room was less than 12



From statement One Number of individuals who moved out was greater than 5
If 6 non siblings move out, number of sibling pairs remaining in the room will not be greater than 4.
If 6 siblings(2 each so 3 pairs) move out-->number of sibling pairs remaining in the room greater than 4
Hence Insufficient
Statement 2 can be ruled out similarly Considering 11 and 10 individuals.
Together insufficient
Hence E

Just a logic question. Reword the question to "did less than 11 people leave?"
