One in four Americans does not know that the Earth revolves around the sun, according to a new study.
AFP reported that the survey was conducted by the National Science Foundation and included more than 2,200 people in the United States.
The quiz reportedly contained nine science questions and the average score was 6.5 correct, barely passing.
The results found that 74 percent of respondents knew that the Earth revolved around the Sun. Fewer than half knew that human beings evolved from an earlier species of animals.
The survey is conducted every two years and will be included in a National Science Foundation report to President Barack Obama and US lawmakers.
