Lisa Mosconi and Her Associates Administered PET Scans to Seemingly

Lisa Mosconi and her associates administered PET scans to seemingly healthy elderly research participants to measure activity in the hippocampus.They found that participants with low hippocampus activity were more likely to develop neurocognitive disorders later in life.How accurate were their predictions?

A) about 60 percent for both mild and major neurocognitive impairment
B) about 90 percent for both mild and major neurocognitive impairment
C) more than 70 percent accurate for mild neurocognitive impairment and more than 80 percent accurate for major neurocognitive impairment
D) more than 80 percent accurate for mild neurocognitive impairment,and nearly 100 percent accurate for major neurocognitive impairment
