In this question all variables represent strings over the alphabet fa, bj. Let SA(u) mean "u starts with a", EB(u) mean "u ends with b", and CAB(u) mean "u contains a substring ab". Then for any strings u and v, the compound statement "(SA(u) and EB(v)) CAB(uv)" is not necessarily true. (Recall that "uv" is the concatenation of u and v.) Select one: True False
