language of all strings

Let Σ = {0,1}. Let C1 be the language of all strings that contain a 1 in their middle third. Let C2 be the language of all strings that contain two 1s in their middle third. So C1 = {xyz| x, z ∈ Σ ∗ and y ∈ Σ ∗ 1Σ ∗ , where |x| = |z| ≥ |y|} and C2 = {xyz| x, z ∈ Σ ∗ and y ∈ Σ ∗ 1Σ ∗ 1Σ ∗ , where |x| = |z| ≥ |y|}

a. Show that C1 is a CFL.

b. Show that C2 is not a CFL.
