Answer is definitely C

Statement 1)
Any negative value would make
x^3 < x^2 true, but so would any value between 0 and 1: example - (1/2)^3 < (1/2)^2
Therefore NS

Statement 2)
You could test values, but realize once again any negative value will make this statment true since a negative number to an odd power will remain negative and turn positive when raised to an even power. Any value greater than 1 will also hold true. Values between 0 and 1 however, will not work here as such values get smaller the bigger the exponent. NS

Combined)
The restrictions laid out by examining both statements commits x to negative values.
