x and y are consecutive positive integers and:

\left{ \begin{eqnarray*} x &>& y\\ x^2 - 1 &>& y^2 - 4y + x - 1\\ \end{eqnarray*}

Which of the following represents all the possible values of y ?

* y \ge 0

* y > 0

* y > 1

* y > 7

* y > 8

No creative solution from me I'm sorry, I'm also going for B.

Explanation:

By definition of condition 1, x>y, therefore x=y+1 (since they are consecutive)

I then just plugged in values, starting from y=1, x=2; y=1 seems to work, therefore y>0 is my answer. Note I start from y=1, as y=0 is not possible due to question conditions (y is positive integer)

Seems a bit too straight forward though, what did I miss?
