I think answer to 7 is "c" since x > 0 and y > x therefore they can't be negative and only 2^6 = 64 satisfies the condition of y > x.

Hi...
For 7th question,
Please think in this way...
(root of 2)^12 = 64
x= Root pf 2 = 1.141 >1.
Y= 12 >x
Got it -

Shoot On Sight is an entertaining drama that addresses racism, politics, .. and terrorism.. It isn�t preachy � just fascinating.. But in the end it pays off as a good, old fashioned police thriller
