What is the primary purpose of the Nelson Denny Reading Comprehension test?

The primary purpose of the Nelson Denny Reading Comprehension test is to measure reading comprehension and vocabulary skills in adults. This assessment is designed specifically to evaluate how well adults can understand and interpret written material, as well as their vocabulary knowledge. The test focuses on adults because it aims to gauge reading abilities that are essential for academic and professional success in higher education and the workplace.

Other options relate to areas outside of the test's focus; for instance, measuring reading skills in children does not align with the test's adult-oriented design, and assessing emotional intelligence or academic performance in mathematics falls outside the scope of reading comprehension and vocabulary evaluation. Thus, the correct answer highlights the test's intended demographic and its specific focus on reading skills in an adult population.
