Four sentences are given below. Find the odd sentence out.
A. A new analysis has determined that the threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70% this century.
B. With research showing that additional warming of about 1 degree C may be the threshold for dangerous climate change, the European Union has called for dramatic cuts in emissions of carbon dioxide and other greenhouse gases.
C. The most dangerous potential aspects of climate change include massive losses of Arctic sea ice and permafrost.
D. “This research indicates that we can no longer avoid significant warming during this century,” said NCAR scientist Warren Washington, the study paper’s lead author.

Correct option is C

Sentence C is the odd one out.
· Sentences A, B, and D all revolve around research findings and data-based conclusions about global warming and the necessary actions to reduce emissions.
· However, Sentence C just states facts about the dangerous aspects of climate change (loss of Arctic sea ice, permafrost) without discussing research, actions, or findings.
· Thus, it breaks the flow and thematic linkage of the rest.
