Complete the Passage
Which of the following most logically completes the passage?
Methane emissions are a significant concern for environmentalists, but another category, perfluorocarbons (or PFCs), is among the lesser-known types of greenhouse gas. A study of refrigerant gases showed that PFCs decompose into harmless compounds relatively quickly. Therefore, if PFCs were banned, the level of greenhouse gas pollution would be greatly reduced, especially since.
