There are many benefits to timing your practice, including:

If P were negative even integer, -p will be positive and (-2)^P will be positive and the minimum value of m will be when p is -2, m = -(-2) + (-2)^-2, which = 1.75

If P were positive even integer, the minimum value of m will be when p is 2, m = -2 + (-2)^2, which is = 2

so m^3 > 1 always
Ok

2)p^3 <= -1
This means that p is a negative integer
For for p=-1, m =0.5, but p = -2, m= 2.25
so m^3 is not always >1
Nope

A)
