Explanation:

Sentences are simple statements that may contain a simple subject, verb, and corresponding objects or complete thought. And to make sentences into the negative form, the most general and common way is to add "not" in the sentences.

And for past sentences, the negative form can be made by using the past form of the auxiliary or helping verb "do" which is "did + not+ the verb".

The given sentences or statements are made in their negative forms as follows-

a) Marchionini and Maurer (1995) did not see libraries as serving three roles in learning.
