Answer choice (C) states that it was more difficult to be accepted to the program in 2007 than in previous years. This checks out, since a smaller percentage of applicants were accepted to the program out of the overall number of applicants. This means that each applicant had less of a chance of being admitted into the program. This could be the result of a more difficult entry exam or fewer open spots, but either way, being accepted is rarer in 2007.
Answer choice (A) is incorrect because it states that the student acceptance rate has grown over the years, while it can be clearly seen in the table that it has decreased. More specifically, it was 50% in 2000, and while it was higher than that between 2002–2005, it decreased from 2005 and onwards down to 20%. Therefore, the claim that it has grown is wrong.
Answer choice (B) presents a claim about the number of students accepted. No claims can be made about the absolute number of students since the chart represents percentages.
Answer choice (D) posits that the acceptance rate will further decrease in 2008. This is not a valid claim because it is impossible to predict without additional information what would happen in the next year.
The correct answer is C
