Question

which of the following options lists two means by which deafness can commonly occur? working in loud environments every day, not having hearing checked in infants diminishing hearing with age, birth defect in hearing process virus that localizes in the head, failing to practice auditory discernment

Explanation:

• Analyze Option 1: Working in loud environments daily can cause hearing loss (a cause of deafness), but not having hearing checked in infants is a screening issue, not a direct cause of deafness.
• Analyze Option 2: Presbycusis (diminishing hearing with age) is a common cause of deafness, and a birth defect in the hearing process (e.g., congenital hearing loss) is also a common cause.
• Analyze Option 3: A virus localizing in the head could cause deafness (e.g., certain infections), but failing to practice auditory discernment is about cognitive auditory skills, not a cause of deafness.

So the option with two valid common causes of deafness is the second one.

Answer:

B. diminishing hearing with age, birth defect in hearing process (assuming the options are labeled A, B, C with A as the first, B as the second, C as the third; adjust labels if needed based on original formatting)
