Many older people lose their hearing for high-pitched sounds due to tissue degeneration near the beginning of the basilar membrane.This is best explained by the ________ theory.

A) gate-control
B) frequency
C) dissociation
D) place

The explanation suggests that the loss of hearing for high-pitched sounds is due to degeneration near the beginning of the basilar membrane, which is consistent with the place theory. The place theory states that different frequencies of sound are processed at different locations along the basilar membrane, and that higher frequencies are processed near the beginning of the basilar membrane. Therefore, degeneration at the beginning of the basilar membrane would result in a loss of hearing for higher frequencies.
