If you like my explanation below, in 5 days I will provide a link through which you can contact me, because the key to maximise your GMAT Score is to maximise your GMAT Verbal Subscore.
Here’s what I will do, in the exact workflow that you see below:
Scan the question stem first to confirm the type trigger: EXPLAIN the discrepancy EXCEPT (so we’re looking for the choice that does NOT explain the discrepancy).
Restate the argument faithfully, labeling:
Premise 1
Premise 2
The discrepancy / contradiction indicator(s) (your “BETWEEN U” and “BETWEEN Z” idea — i.e., the phrasing that makes the two premises clash)
Analyze all answer choices by applying Process of Elimination as follows:
Eliminate choices that do explain the discrepancy by connecting to both premises and resolving the contradiction.
Keep choices that do NOT explain it because they:
connect to only one premise, or
connect to neither, or
connect to both but fail to resolve the contradiction.
The last remaining choice is the EXCEPT answer
Question (type trigger): EXPLAIN the phenomenon EXCEPT
Trade in Glasgow doubled between 1750 and 1765 (1750 = first bank opens; 1765 = first government banking regulations in Scotland).
We need the choice that does NOT contribute to explaining why trade doubled by 1765.
Apply POE (keep only what does NOT explain the doubling)
(A) Could explain: more England–Scotland trade ⇒ Glasgow’s trade can rise. Eliminate.
(B) Could explain: lower tariffs in 1752 ⇒ more imports through Glasgow ⇒ more trade volume. Eliminate.
(C) Could explain: banking + paper money ⇒ easier/faster transactions ⇒ supports more trading activity. Eliminate.
(D) Could explain: better roads 1750–1758 ⇒ cheaper/faster movement of goods to/from Glasgow ⇒ more trade. Eliminate.
(E) Problem: the initial government regulation begins in 1765 (the endpoint). That regulation would mainly affect the period after it is implemented, so it does not plausibly contribute to explaining the trade increase over 1750–1765 (the run-up to 1765). Keep.
Correct answer: (E)
