question 405

Multiple Choice

The loss of arctic ice is accelerating as a result of a form of positive feedback. As arctic ice melts, the arctic icecap reflects fewer rays from the sun. When this happens, more rays are absorbed by the surrounding ocean, which increases its temperature. As the temperature of the ocean rises, more arctic ice melts.

• A) Argument; conclusion: When this happens ... which increases its temperature.
• B) Argument; conclusion: As the temperature of the ocean rises ... ice melts.
• C) Argument; conclusion: The loss of arctic ice ... positive feedback.
