1 gives value of x
if x is negative y is positive - answer yes
if x is negative y is negative - answer yes
2 gives value of y
hence both 1 and 2 are indivudially not sufficient a,b,d eliminated
c/e remain
(1) -1 < x < 2
(2) 3 < y < 5
as x and y are not mentioned as integers
y is positive
x can be either + or -
(E) imo
