Answer
# Brief Explanations:
To estimate the mean age of voters accurately, the sample should be representative of all voters. Randomly selecting 100 people who voted in the last election gives a more unbiased sample compared to the other options. Selecting only voters over 30 years old or those who voted for a particular candidate would introduce bias, and selecting newspaper - readers is not related to voters.
# Answer:
randomly select 100 people who voted in the last election
