China's share of the global economy has decreased since peaking at 19% in 2021. What describes this trend?

• A. Decreased
• B. Increased
• C. Stayed the same
• D. Fluctuated

Answer: (A)

The trend being tested is how a country’s portion of the world’s economy changes over time. If it has decreased since its peak, the correct description is that the share has decreased. After peaking at 19% in 2021, China’s relative size of the global economy fell, meaning its slice of the world economy became smaller even if its own absolute GDP may have grown. This happens because the global economy can grow at different rates, and China’s growth may slow or others may grow faster, reducing its relative share. The other options don’t fit because an increase would mean the share rose after the peak, staying the same would imply no change, and fluctuating would imply ups and downs rather than a clear decrease from the peak.
