IMO EA new private college offers a course which prepares students for a career in which only 7% of the professionals are successful financially in the related industry. In a radio commercial, the course is presented as a guarantee to financial success based on that career. Clearly, such a guarantee warrants charges of false advertising.
Information available :
1. course - prepares students for a career in which only 7% of the professionals are successful financially
2. But in the radio commercial, course guarantees success
Charge : false advertising
What can help us evaluate the argument/conclusion?
1. Eliminate out of scope answers
2. We do not know HOW many students actually took the course
3. We do know anything about how easy/tough the course is
4. We do not know anything about any other mistakes/reasons owing to which the success is 7%
Keeping the above thoughts in mind, let's go through the options.
The answer to which of the following would be most useful in evaluating the argument?
(A) Is the percentage of professionals that did not take part in the course in the new private college lower than 93%?
Out of scope
(B) Did any of the professionals included in the 7% not graduate from the course?
We are not bothered about who graduated
(C) Did more than 50% of the professionals graduate from a similar course offered by another college?
Red flag- Another college
(D) How many students does the college accept into a single course?
Once again, results might vary here. If the number is 100, 7% might be a small rate of success.
(E) What percentage of professionals have participated in a course that trains for this specific career?
