p 376 # 2, 10bc, 13, 15, 14*, 24,

p 376 # 29, 38. 

Read p 376 # 39, but don't work it. If all their claims 
are correct, do they actually prove that anything {must} 
happen? 

(*) For problem 14, don't work it by induction. 
Instead, use this idea. The intersection of E_1 thru E_n
is the complement of the union of the complements of E_1 
thru E_n. Now apply problem 15, which you can take as given
whether or not your own solution worked out.
