Question

Which of the following does not require attribution?. . I. information found in multiple sources. . II. information directly observed. . III. quotations from a public figures

Answer 1

The answer is B: I and II

Answer 2

If you need only one option, then I'd say that the option that does not require attribution is II. information directly observed.
Attribution means that you give credit to the author, so III is definitely the thing you need to attribute. I am not sure about I - if you have two answers, I'd choose I and II - if only one, then II.
