Answer: Choice B.
Step-by-step explanation:
Censuses are complete data collections of every member of a population.
For example, the U.S. Census occurs every 10 years and documents every member of the American population.
Choice A only surveys the first ten students; this is not a complete census.
Choice B surveys all the students in the targeted data group. This is a census.
Choice C only surveys the male students, even though there are female students in his data group. This is not a census.
Choice D only surveys the girls on the soccer team, even though there may be boys on the team as well. This is not a census.
Choice E only surveys his friends in the chorus, even though there may have been people that were not his close friends. This is not a census.
Only choice B is a complete census.
