Q 16 - if |b| < a, even though a1+a2...+an is absolutely convergent, I think b1+b2...+bn could be absolutely divergent.

No, the comparison test will give the absolute convergence of the b_n from the absolute convergence of the a_n. (There was some strange issue here in which some of the solution commentary leaked into the main question, but I think I fixed these issues.)
