Explanation

Answer: A

PASSAGE

Data/Graph for question

A climate researcher is analyzing trends in global temperature anomalies from 1880 to 2020. The data shows the deviation from a long-term average.

Based on the graph, which claim about global temperature is best supported?

A. Global temperatures have remained stable since 1880.✓ Correct
B. The rate of temperature increase accelerated significantly after 1980.
C. Temperature anomalies peaked in the 1940s and have declined since.
D. The coldest years on record occurred after 2000.

Detailed Explanation

The graph shows relatively flat temperatures from 1880-1980, then a sharp upward trend after 1980. This demonstrates accelerated warming in recent decades.

Key Evidence:

• "Sharp rise after 1980"

• "Steeper slope in recent decades"

Why others are wrong: A (The graph clearly shows an upward trend, not stability.), C (Temperatures continue rising past 1940.), D (Post-2000 shows the HIGHEST temperatures, not coldest.).
