1. when a change to a system causes a cycle of change that gets more and more intense, or amplified, it is referred to as ______ feedback.

a. negative
b. positive
c. neutral
d. oscillating

Explanation:

To solve this, we recall the definitions of feedback types:

• Negative feedback counteracts changes (stabilizes).
• Positive feedback amplifies changes (intensifies a cycle).
• Neutral feedback has no net effect.
• Oscillating feedback involves periodic fluctuations (not about amplification).

The question describes a cycle that “gets more and more intense” (amplified), which matches positive feedback.

Answer:

B. positive
