INSTRUCTIONS: The fоllоwing selectiоns relаte to distinguishing аrguments from nonаrguments and identifying conclusions. Select the best answer for each.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.
