LSAT 148 | Section 2 | Reading Comprehension: Q11

RC Question 11 Explanation

DISCUSSION: The last sentence of the second paragraph raises a question: why did the Great Migration continue and speed up while the income gap was narrowing?

The 3rd and 4th paragraphs propose an explanation for this question.

___________

1. The passage doesn’t mention any misguided work. The fact that a historical question is uncertain doesn’t mean past work is wrong. It might merely be incomplete.
2. This wasn’t it. The final sentence asks a question. It doesn’t explain anything.
3. It’s true the sentence says the income gap was narrowing, but that’s referring to the period after 1915, during the rest of the Great Migration (which ended in 1960). And even when a gap is “narrowing”, there is still a gap. Northern wages are actually still higher today, if I recall correctly. 
4. CORRECT. See the analysis above. The sentence asks why the Great Migration sped up despite a declining income gap. The 3rd and 4th paragraphs try to answer this question.
5. Rubbish. The authors spend paragraphs 3 and 4 trying to explain the Great Migration. Asking a question doesn’t mean you think the question is unanswerable!
