Question

The Earth’s average surface temperature was the highest in 2005 since accurate records have been kept for the last ____ years.


Choose the best answer from the options below:
A 400
B 500
C 50
D 125

Answer 1

The most accurate answer based on historical climate data is **A 400**. Accurate records of Earth's surface temperature have been maintained for around 150 to 200 years, but estimates of climate data extend back further. Therefore, 400 years aligns best with the extended historical context of temperature records, capturing broader climatic trends.
