in all questions  $(M^n,g)$ is a compact $n$ dimensional manifold of negative curvature

1) let $\alpha$ be a simple closed geodesic loop in $M$ if $n=2$ then we know that the geodesic in the free homotopy class of $\alpha$ is simple . i think if $n>3$ then this will stop being true can but can someone give me a counter example ? 

2) suppose $n>3$ and let  $\alpha$ be a simple closed geodesic loop at a point $p$ in $M$  can $\alpha$ be homotopic ( with respect to $p$ ) to a power of another closed curve at $p$

3) suppose $n>3$ let $p$ be a point in $M$ . Let $\Gamma$ be subgroup  of $\pi_1(M,p)$ generated  by {$\alpha \in pi_1(M,p)$ such that $ length(\alpha)= Systole(M,p)$} . suppose now $\Gamma$ is cyclic does that  necessary mean that there exist a unique $\alpha$ such that $length(\alpha) = Systole(M,p)$
