A study showed that children who play a musical instrument score higher on tests of spatial reasoning. The researchers concluded that the process of learning to read and play music develops the brain's spatial processing centers.
Which of the following, if true, most seriously weakens the researchers' conclusion?
- Children who are naturally strong in spatial reasoning are more likely to be drawn to music programs and to thrive in them.
- Many of the children studied were also concurrently enrolled in accelerated mathematics and laboratory-science courses at school.
- Playing an instrument demands fine motor coordination, sustained discipline, and steady, hours-long practice over many months.
- The study tracked children aged 6 to 12, a developmental window marked by unusually rapid maturation of the growing brain.
- Learning music is, beyond any rival activity whatever, the single most powerful means of improving a young child's spatial reasoning.
