PrepTest 90+, Section 2, Question 7
Researcher: In a recent study of elementary school computers, we found that all keyboards and most monitors were positioned higher than recommended for children. Consequently, children were seated in ways that encouraged craned necks, awkwardly placed wrists, and other unhealthy postures. Evidently, most elementary school computers are installed without consideration of their effect on posture, and thus put children at the same risk for repetitive stress injuries as office workers.

Which one of the following, if true, most seriously weakens the researcher's argument?
The recommended height for computers is different for children than for adults.
Children spend more time working with computers at home than at school.
The greater suppleness of children's bodies makes them less susceptible than adults to repetitive stress injuries.
Office workers' keyboards and monitors are usually not at the recommended heights for healthy postures for adults.
Office workers are more likely to report injuries than children are.
