In the book "The Giver" by Lois Lowry, the Committee of Elders consulted with the Giver for his wisdom and memories of the past. The Giver is the keeper of collective memories of humanity which include both positive and negative experiences. The Committee of Elders sought his guidance to make wise decisions based on the knowledge of the past, as they were responsible for governing the community and ensuring its smooth functioning.

To find this answer, you can either read the book "The Giver" or refer to online summaries and analyses of the story. By understanding the role of the Committee of Elders and the significance of the Giver's memories, you will be able to grasp the purpose for which the Committee consulted the Giver.
