Final answer:
Jon's ruptured eardrum will likely cause trouble in hearing faint sounds due to the impaired ability to sense vibrations, which is crucial for hearing.
Step-by-step explanation:
Jon had an ear infection and his right eardrum ruptured. While the eardrum is healing, Jon's doctor told him that his hearing would be impaired in that ear. The correct answer to this question is that Jon may have trouble hearing faint sounds. This is because the eardrum is a crucial part of the ear's ability to sense vibrations caused by sound waves. When the eardrum is damaged, as in Jon's case, it can hinder the transmission of these sound vibrations, leading to difficulty in hearing especially more subtle sounds. A rupture doesn't typically affect balance, language comprehension, or digestion as those are not directly related to the function of the eardrum.
