Critical Reasoning (CR) | Re: Harvard business school claims that 70 percent of its incoming class

Harvard business school claims that 70 percent of its incoming class boasts a score of 700 or higher - the highest amongst the top 10 schools.

If the statements above are true, which of the following must also be true?

A) The percentage of students with scores higher than 760 is likely to be higher at Stanford than at Harvard.

B)
