PrepTest 116 - Section 2 - Question 4

Show summary

A study claims that the average temperature on Earth has permanently increased, because the average temperature each year for the last five years has been higher than any previous yearly average on record. ████████ ███████ ██ ██ ██ ███ █████ ██ ███████ ████████████ ████ ████ ████████████ ████ ██████ █████ ███ █████ ██████ ████ ██ ███ ██████ ████████████ ██ ███████████ ████ ███ ██████ ██████████

Summary

A study concludes that the average temperature on Earth has permanently increased. Why? Because for the last five years, the average temperature has been higher than any previous average on record. However, sometimes random fluctuations in temperature can cause periods of up to ten years to have record high average temperatures.

Strongly Supported Conclusions

The last five years of record high temperatures do not necessarily indicate that the average temperature on Earth has permanently increased.
