Answer:
From all the statements, the only one right is The main purpose of conducting a census every 10 years is to determine representational apportionment.
Step-by-step explanation:
The first option is wrong because voting is a right for every citizen in many countries including the U.S. and they are only required a certain age to exercise their vote. The age in which they are considered adults by law.
The second option is wrong because the main point of census workers is to find all the citizens and get their information.
The third option is right because 10 years is the time-lapse considered to be a major barrier between generations and their changes.
The fourth option is wrong because national census data is the factor that determines the majority of apportionment changes.
