Question 1

How many first-year students did not take the placement exam in 1995?

Your Answer: Option(s)

Correct Answer: Option(s) D

Rationale

70 first-year students did not take the placement exam in 1995.

This figure represents the number of students who chose not to participate in the placement exam, as indicated by the data provided.

A) 57
This number is lower than the actual count of students who did not take the exam. It does not reflect the total number of first-year students who chose to skip the placement exam in 1995.

B) 63
While 63 is a plausible figure, it is still less than the correct count of 70 students. This choice fails to account for the total number of students who opted out of the placement exam.

C) 66
This option is also less than the correct answer. The number 66 does not encompass all the first-year students who did not take the exam, making it an incorrect choice.

D) 70
This is the accurate answer, representing the total number of first-year students who did not take the placement exam in 1995, according to the data.

E) 73
This figure exceeds the actual count of students who did not take the exam. It inaccurately suggests that more students opted out than what the data indicates.

Conclusion
In 1995, the number of first-year students who did not take the placement exam was 70, making option D the correct choice. Other options fall short or exceed this number, failing to represent the actual data accurately. Understanding these figures is important for assessing student participation and the implications for academic placement strategies.
