Answer to Question 1

The Chairman can take one simple random sample from each department for comparison purposes. That means he is taking a stratified random sample, where the strata are the five departments.

Answer to Question 2

Use cluster sampling, where each city block is a cluster. Select a certain number of state counties at random, then for each city block selected, sample each household in that county.
