Answer:
Someday, humans will run out of fossil fuels.
Step-by-step explanation:
A factual statement is defined as the statements that are based on true facts and research.
A factual statement about natural resources is that "Someday, humans will run out of fossil fuels" because fossil fuels are non-renewable resources that take thousand or many years to form and are present in a limited amount in our environment. Many kinds of research are made on this topic which says that if fossil fuels will be used at the same speed by humans, someday humans will run out of fossil fuels.
Hence, the correct answer is " Someday, humans will run out of fossil fuels."
