Answer
# Brief Explanations:
- Politicians may have more reasons to visit the capital due to work - related activities, so their sample is likely biased.
- People who don't like to travel are less likely to visit the capital compared to the general population, introducing bias.
- Those living within 100 miles of the capital are more likely to have visited it than the whole country's population, causing bias.
- Liking chocolate has no relation to visiting the capital, so this sample is unbiased.
# Answer:
