Explanation:

For the first question, an identifier column uniquely labels each row; dog breeds are unique entries for comparison, while other options are attributes or non-identifying terms. For the second question, the text states people care about personality, average weight, and activity level as relevant info; these are valid column headings, while the others are either a specific activity value, unrelated, or the table name.

1. Breed
