C.A.B.D.E

A Finished before B but behind C; this gives C the first position and A the second position and B the third position in the limit of the first sentence.

D finished before E but behind B; This gives D a position behind B and E a position after D.

NOTE; from sentence 1 B finished before any letter in the second sentence... so those letters will take their place after B.
