Researchers found that children's academic achievements grow in correlation with their parents' income. Some researchers have attributed this trend to the correlation between parents' income and the extent of their education, which means that high-income families can also provide better academic support; however, other researchers have attributed it to the ability to invest larger amounts of money in better educational assistance.
Which of the following, if true, would support one of the two hypotheses and undermine the other?
A. Children who have higher academic achievements at school earn more money when they grow up.
B. Doctors have high income, but they rarely see their children.
C. For university students of economics, the higher their grades, the more expensive their tuition.
D. In after-school academic enrichment courses, children from low-income families achieve more than do other children.
E. Children with better achievements help improve their parents' education.

E. Children with better achievements help improve their parents' education.
According to the source B is the right choice as it undermines one hypothesis, but in my opinion it does not necessarily support the other hypothesis.

if you use elimination method, B is the closest answer among the choices.
First what are the two hypotheses according to the stem?
1. High income fams give better academic support
2. Able to invest huge(r) money in better ed assistance
Doctors have high income---- they can invest huger quid in educational assistance
Doctor rarely see their children ---- how will parents provide academic support to children they barely see?
The only other option that undermined one of the hyp is D but it didn't support the other.

We can do POE to find correct answer.
A) Talking about children earning money, whereas argument is about Children's academic achievements with their parents' income. Irrelevant to the linkage.
B) Doctors have high income (1), but they rarely see their children(2). 1-- Strengthens first hypothesis. 2--Undermines second hypothesis.
C) Only talking about University of Economics, however the argument is about a generic situation.
D) Irrelevant to the linkage.
E) Out of scope. Children helping parents is nothing to do with the Hypothesis.
So correct answer is B.
