PASSAGE
Text 1 The greenhouse effect is a natural process. Gases in the atmosphere trap heat from the sun, keeping the Earth warm enough to support life. Text 2 Human activities, such as burning fossil fuels, have increased the concentration of these gases. This 'enhanced' greenhouse effect is trapping too much heat, causing global temperatures to rise dangerously.
How does Text 2 distinguish the current situation from the process described in Text 1?

B. It argues that the greenhouse effect is a myth.
C. It says the Earth is getting colder.
D. It claims that plants caus the warming.

Key Evidence:
• "natural process"
• "Human activities"
• "trapping too much heat"
Why others are wrong: B (Confirms it.), C (Rise.), D (Fossil fuels.).
