Which of the following statements about the census is false?
a.
the census is used only to get an accurate population count.
b.
the united nations recommends that the census be taken every 10 years.
c.
the census is conducted via written questionnaires.
d.
the census gathers information about people and households, such as age, race, ethnicity, religion, and languages spoken.

A).  No.  It collects all the details listed in choice-D.

B).  I don't know what the UN recommends, but in the US,
the Constitution requires a census every 10 years.

C).  It used to be 100% live face-to-face visits to every household
by "census takers".  They've backed off from that quite a bit, mainly
because that process is so expensive.  There are still a lot of live,
face-to-face home visits, but I think that now the questionnaires do
outnumber the live visits.

D).  Yes, yes, yes, and a lot more besides.  It's really fascinating to
search "census" on line, and see the enormous range of information
that's in it. 

Which one is the underlined word?
