PTF97.S1.Q11 - The book is either by Deerson or else by Jones

Hi everyone! I am a little confused on this question, specifically on Answer Choice E.
Because it is a Pattern MOR Q, I broke down the logic in the stimulus too:
B -> D or J
D or J m-> QP
B probably QP
I represented the conclusion with probably because I believe it is important, as the question does not fully claim B must be QP.
Working through the wrong answers:
A: Incorrect, talks about Mercedes Identifying most trees, but that does not really fit with the structure we need
B: Incorrect, assumption required between creaking gate and hearing somebody break into house.
C: Incorrect, similar to our argument, but does not include most, and includes a negation our argument does not have
D : Correct: M -> L or K m-> MD Conclusion: M probably MD. Direct mimic of Q Argument
E: This is the one I am struggling with why its incorrect.
Laying out the logic for this one I have:
T -> D or S
D or S m-> CS
T probably CS
I know I am missing something, but all I see here is an argument that also mimics the Qs argument. Maybe because the conclusion comes first?
Thanks for the help!
