In the concluding paragraph of the given passage, the writer’s tone can be best described as

The correct option is Optimistic.

Explanation:

To determine the tone of the writer in the concluding paragraph of a passage, we look at the word choices, overall perspective, and the message conveyed at the end.

Step-by-Step Breakdown of Tones:

1. Optimistic: An optimistic tone is characterized by hopefulness, confidence, and a positive outlook on future outcomes or possibilities. When a writer concludes on a hopeful note, highlighting potential, progress, or positive expectations, the tone is optimistic.

2. Despairing: A despairing tone reflects complete loss of hope, sadness, or discouragement. This would involve focusing heavily on defeat, failure, or unavoidable negative consequences.

3. Laudatory: A laudatory tone involves expressing praise, admiration, or commendation towards someone or something specific.

4. Apologetic: An apologetic tone shows regret, acknowledgment of fault, or expressing excuse for an action or viewpoint.

Since the concluding paragraph expresses hopefulness and a positive future outlook, the writer's tone is best described as Optimistic.
