Among those automobile mechanics who own their own garages and completed a qualifying course at Main Street Technical School, 35% earn above $80,000 a year. Among those who own their own garages but did not complete the qualifying course at Main Street Technical School, only 10% earn above $80,000 a year. These figures indicate the importance of technical education in getting a higher salary.
The argument above depends on which of the following assumptions about the people mentioned in the statistics?
A. At least one-third of the group of people who did not complete the qualifying course would today be earning more than $80,000 a year if they had completed the course.
B. The group of people who did not complete the qualifying course and the group who did are comparable in terms of factors that determine how much people are paid.
C. Most of those people who did not complete the course did so entirely because of the cost of the course.
D. As a group, those persons who completed the course are more competent as mechanics than the group that did not.
E. The group of people who did not complete the qualifying course and who today earn more than $80,000 a year are more capable than the group that completed the course.

It's a cause effect assumption question.
The cause is education, the effect is higher salary.
The assumption for the conclusion to be true is that education must be the ONLY cause, that every time the cause happens, the effect does too.
B might be tempting, We should ask our-selves, should graduated mechanics and not-graduated mechanics be comparable under factors for salary increase for the conclusion to be true? The answer I think it's yes, because if there are OTHER CAUSES then data are not comparable and thus the hypotized causal effect in the conclusion can't hold.
A on the other way might be tempting too, but if you try to negate you could say that "less than 1/3 of people increased their salary after graduating". It still suggest a causal - effect relationship even if it's weak. Thus B

B is our answer. Let's say that the location determines the wage rate for garages and all educated garage owners are in the area that pays the most. So, this weakens the conclusion.
B makes sure that we don't deviate to an alternate solution
