Alphabetical order…don’t feel bad if you had to recite the alphabet to answer this one (I did!) It’s better to feel silly than to be wrong.
K-L-M-N is the only alphabetical order for the first four speakers. Then five can lecture about either O or P, since both letters come after N. That gives us two options, so A is CORRECT.

I didn’t understand this answer. if 1st speaker can only do K L M, 2nd K L M N, 3rd MN, 4th M N and 5th N O P
how is there 2 options in alphabetical order?
1st speaker would have to do K
2nd would do L
3rd M
4th N
5th would do O and P.
this scenario does 6 lectures total but the question says 5 lectures over the course of 5 weeks unless we count O and P as one lecture then we have 5. this is one way of the possible alphabetical order but what would be the second one?
Are we assuming that for the 5th week the final lecturer would only teach O? So we would have KLMNO as one answer and KLMNOP as choice 2?
