Read the paragraph from the PRO article. “To be sure, the Census Bureau's annual American Community Survey does ask a citizenship question. But while more frequent, those surveys are limited samples, about 3.5 million out of roughly 126 milion households. The sample numbers are then extrapolated for the country as a whole. But even then, the bureau doesn't include an estimate of the uninsured who are in the U. S. illegally.”
How does this paragraph contribute to the author's argument?
A. It uses a comparison to show that many uninsured or illegal immigrants do not respond to the current census truthfully
B. It uses a statistic about the number of households that respond to the census, suggesting that number would improve
C. It uses a precedent to show that the citizenship question is already being asked, but it is ineffective in its current form.
D. It uses an estimate of the samples currently taken by the government to explore the use of a citizenship question in limited scope.
