For some context, I missed 5 in this section (including this one) and 4 in the other LR section which is typical for me. I BR'd my other misses and skips in this section and was able to get them all correct. This question, I haven't been able to conclusively state why all AC are either right or wrong. I think I'm messing up my diagramming... so if you see glaring errors below, please tell me where I'm screwing up!
I just guessed (A) during the test as I was out of time. In BR I diagrammed as follows:
L > NUem
NU m> WHem
_
L m> WH
which is flawed argument form
A > B m> C
_
A m>C
I skimmed over the AC for quick eliminations and I eliminated C because it contains "never" in the conclusion.
Then I began diagramming the remaining AC:
(A) My question here is do I diagram "probably" in the conclusion as "most"?
CMSMour
CMSM m> REH
_
CMSMour m> REH (probably diagrammed as most>)
I eliminated (A) because it follows a valid argument form:
Ax
A m> B
_
Ax m> B
(B) I diagrammed "generally" as most...
REH m> EG
REHour > /EG
_
REHour > EG
I eliminated (B) because while it doesn't follow the same invalid form as the stimulus
(D)
Cour > MSM > EG
_
C > MSM m> EG
I think this looks like:
Ax > B > C
_
A > B m> C
A m>C
therefore matching the question's flawed reasoning.
(E) I'm having trouble diagramming the first sentence so I reconstructed "Most cities that are regional economic hubs contain major shopping malls." to "Most cities that contain major shopping malls are regional economic hubs." Does this change the nature of the sentence?
C > MSM m> REH
Cour > MSM
_
Cour m> REH
OR am I just complicating this and its as easy as:
REHcity m> MSM
OURcity > MSM
_
OURcity m> REHcity
which follows:
A m> B
Cx > B
_
Cx m> B
E just confuses me... and I can't figure out why.
I haven't watched the explanation, nor have i looked to see what the correct answer is because I'm really trying to work this out! Thanks in advance!
While I appreciate your concern for my health, Ohno, you mis-inferred the point of my post. Colloquially, a reach school is something we hope for, but don't necessarily expect admission to.
Note that I did not solicit advice on how to get in to WUSTL. I'm starting a conversation with other applicants who hope for, but don't necessarily expect admission to WUSTL.
