Explanation:

• First question: Group A delta fibers are responsible for transmitting sharp, immediate pain signals. When Blake cuts his thumb, this type of fiber is activated.
• Second question: Group A delta fibers also respond to thermal stimuli (like hot water). So, when Blake feels the hot water while washing dishes, these fibers are at work.
• Third question: Group A beta fibers are associated with touch and pressure sensations. A tap on the shoulder is a light - touch/pressure stimulus, activating these fibers.

Answer:

• First question: group A delta
• Second question: group A delta
• Third question: group A beta
