What does the Question Stem tell us?
Inference (Most strongly support)
Break down the Stimulus:
Read for Causal, Conditional, Contrast, Quantitative language.
This has some causal/conditional language. Big sized group --> conflicting economic interests --> no unity. The contrapositive of that chain would be "if you want unity, you need harmonious economic interests, which means you shouldn't exceed a certain size". The contrast language of "YET" creates the friction point. The last sentence is saying "Influencing legislation ---requires--> political impact ----requires--> unity", so we could extend that all the way from "influencing legislation" to "do not exceed a certain size".
Any prephrase?
There is a big chain (although the wording is hedged, so I wouldn't expect something strongly worded). Influencing legislation requires political impact, which requires unity, which requires harmonious interests, which requires staying under a certain size.
Answer choice analysis:
A) Extreme, "generally". New comparison, "More/less influential". The stimulus only spoke of yes/no influential (relative vs. absolute language). Also, the trigger for losing influence is "exceeding a certain size", not "expanding".
B) Extreme, "it is necessary". And "effective functioning" of a democracy is out of scope.
C) Extreme, "ignore with impunity".
D) Yup, this looks like it's tesitng the connection between "influencing legislation" and "exceeding a certain size".
E) Extreme, "generally". Also, "over time" is not the same as "exceeding a certain size".
The correct answer is D.
Takeaway/Pattern: When we see chains are being tested, stuff mentioned twice (like "conflicting interests" and "unity") are the roadmap to the 'missing link' between the ideas mentioned only once: "exceeding a certain size" and "having the impact required to influence legislation".
