Heather is a 10-year-old living in an isolated rural community. The local school closed two years ago, and Heather has not been to school since then. A test performed during the last year of the school's operation revealed that Heather's IQ was 107. Which of the following is probably closest to her current IQ?

Question

Quizplus · Accepted Answer

Studies have shown that lack of education and exposure to intellectual stimulation can lead to a decline in IQ. Since Heather has not been to school in two years, it is reasonable to assume that her IQ may have decreased slightly. Option B, 95, is slightly lower than her previous IQ score and takes this potential decline into account. Option A, 107, assumes that her IQ remained the same despite the lack of schooling, which is unlikely. Option C, 105, and option D, 85, both assume a higher degree of decline than what is typically observed.
