Answer to Question 1

B
Every stage of a sampling process requires its own sampling frame.

Answer to Question 2

In many situations, the decision rule is to do nothing with the missing data and simply leave the item blank. However, when the relationship between two questions is important, the editor may be tempted to insert a plug value. If so, several choices are available:
(1) Leave the response blank.
(2) Plug in alternate choices for missing data.
(3) Randomly select an answer.
(4) Impute a missing value based on the respondent's choices to other questions.

Most statistic programs accommodate an occasional missing response through the use of pairwise deletion, which means the data that the respondent did provide can still be used in statistical analysis.
