Context Free Language ~ pumping theorem

sigma = {(A - Z, a - z, blank} (that is, sigma is the upper- and lower-case English alphabet, plus the bank). L = {w elementof: there exists at least one duplicated, capitalized word in w}. For example, Chris always does what's best for Chris elementof L. You are given the first step in a that L notelement CFLs. Complete the proof. Let L' = L intersection Aa*b*Aa*b*
