(C) Lincoln, discovering the secret that the Yankee peddler had learned in young manhood before him, knew

(D) In young manhood Lincoln discovered the secret that the Yankee peddler had learned before him;

      (E) Lincoln, discovered in young manhood the secret that the Yankee peddler had learned before him, knew

2/3 split between has/had usage.

usage of 'had' should be correct because the time of reference is 'young manhood' and yankee peddler discovered before this time of reference. right ??

A, B out.

C is out.  discovering..had..knew

Between D & E..I am not sure !

in none of the sentence 'the secret' and 'how to use a good story to generate good will.' are not juxtaposed to each other...and that gives me the feeling that we are talkin about a different secret..
