Question

Quizplus · Accepted Answer

According to the given analogy, the 14-billion-year history of the universe is represented by a 100-yard football field. Therefore, each yard on the field corresponds to 140 million years of the universe's history. The existence of human beings on this timescale is a mere blip in time. Homo sapiens emerged only about 200,000 years ago. Therefore, the distance from the goal line to the one-inch line would likely represent the timeline of human existence. That corresponds to just over 5,000 years on the analogy of the 100-yard football field. Therefore, the best choice is D, the one-inch line.
