Quizplus · Accepted Answer

According to the question, world population grew from "________ billion" to over 6 billion. The range of options in the answer choices is between 2.5 and 5, so we can eliminate choices A, B, and C. Additionally, it is unlikely that the world population would only grow by a factor of 3 in 50 years, so we can eliminate choice D. Therefore, the best choice is E, 2.5 billion.
