We need to see if x<1 or not.

Statement 1 ->
x^2>x

x<0
or
x>1

Not sufficient

Statement 2 =>

x>0

Not sufficient

Combing the two statements => x>1

Hence we have a definite NO for x<1

Thus x is never less than 1

Sufficient

SMASH THAT C

Need to figure out if x-1<0
(1) x^2-x>0
x(x-1)>0
It happens only when x and x-1 have the same signs. As long as we have two cases x can be more or less than 1.
Insufficient
(2) x^3>0, hence x is positive by itself however from this statement we cannot deduce whether x<1
Insufficient
(1)+(2) We can cross out negative case from statement (1) and we are left with x(x-1)>0, which means that x>1 and the answer to the main question will be NO

Is x < 1?

1) \(x^2\) > x
2) \(x^3\) > 0

Considering Statement 1 alone:
\(x^2\) > x
This is true for x > 1 and also for x < 0........INSUFFICIENT
AD out, BCE stays.

Considering statement 2 alone:
\(x^3\) > 0
=> x > 0, so can be < 1 and > 1............INSUFFICIENT

Considering both the statements together:
Both statements hold true only when x > 1.
SUFFICIENT.

The answer is C.
