Step 1

This means that the answer options a and b can be eliminated. Now, let's consider the remaining options: c. All senses decline with age, most dramatically by age 50 and then increase thereafter. This option suggests that the ability to perceive taste and smell Show more…

Key Concepts

Aging and Sensory Decline

This concept refers to the general phenomenon where the efficiency of sensory systems decreases over time due to physiological changes in receptor cells and neural pathways. As people age, many of these changes lead to reduced sensory acuity, affecting various senses including hearing, vision, taste, and smell.

Taste and Smell Perception

Taste and smell perception are specifically impacted by aging as the receptors in the mouth and nose gradually lose their sensitivity and regenerative capacity. This reduction results in a diminished ability to detect flavors and odors, which can affect nutritional choices and overall quality of life.
