Hey i was wondering if any of you have this one handy to tell me how to get answer #19.... i got the remaining 4, but the answer booklet i had was A for 19 being the correct answer and I don't understand how...

ahh nevermind, such a stupid mistake..."complete list of the students who review only Sunset"....i was thinking how could L be the only one in S in any possible scenario...

So guys and gals read the question carefully!
