(a)
Interpretation:
Whether the statement “Each year after 1950 had an average global temperature higher than 1901-2000 average temperature” is true or false should be determined.
Concept introduction:
Earth is the planet that holds a variety of climates ranges from extreme cold at poles and heat at the equator. The global climate can be said as an average of regional climates. The history shows that the global climate gets cooled and also gets warm. The diverse climate such as extreme cold, sunny, dry, windy, and humid of the earth occurs because the earth revolves around the sun.
(b)
Interpretation:
Whether the statement “average global temperature before 1940was lower than 1901-2000 average temperature” is true or false should be determined.

(c)
Interpretation:
Whether the statement “the warming in the time period 1970-2015 occurred at a faster rate than in time period 1900-1950” is true or false should be determined.

d)
Interpretation:
Whether the statement “a cooling trend is shown between 1880 to 1910” is true or false should be determined.
