Select the most appropriate verb to complete the sentence correctly: He _________ the role of the organization in creating environmental awareness among the people.

Introduction / Context:
This vocabulary-based question tests your ability to choose a verb that fits both the meaning and the context of a sentence about environmental awareness. The focus is on how someone speaks about or responds to the role of an organization. You must select the verb that expresses praise and approval for the organization's contribution.

Given Data / Assumptions:

• The subject “He” is evaluating the role of an organization.
• The organization is involved in creating environmental awareness among people.
• The context is positive, as environmental awareness is generally considered a good activity.
• The verb must show his attitude toward that role.

Concept / Approach:
Different verbs carry different connotations. “Commend” means to praise formally or express approval. “Collaborate” means to work together. “Command” is to order or demand, and “contrast” is to compare in a way that highlights differences. Because the sentence talks about “the role of the organization”, the verb should express approval of that role rather than cooperation, ordering, or comparing.

Step-by-Step Solution:
First, understand that creating environmental awareness is something positive.Next, check which verb can naturally follow “He ______ the role of the organization”.“Collaborated the role” is ungrammatical; one collaborates “with” someone, not “the role”.“Commanded the role” would imply ordering the role, which does not fit.“Contrasted the role” would mean he compared it with something else, not praised it.“Commended the role” means he praised the role of the organization, which perfectly matches the positive context.

Verification / Alternative check:
Insert each verb into the sentence and read it aloud. Only “commended” gives a smooth, natural expression: “He commended the role of the organization in creating environmental awareness among the people.” This clearly conveys that he appreciated and praised their efforts.

Why Other Options Are Wrong:
“Collaborated” needs “with” and refers to working together, not evaluating. “Commanded” refers to ordering or having authority, which is not the idea here. “Contrasted” suggests comparison, not approval. None of these express positive praise for the organization's environmental work.

Common Pitfalls:
Students may be tempted by words that look or sound similar, like “commanded” and “commended”, or may choose a familiar word like “collaborated” without checking whether it fits grammatically. Always think about both meaning and typical usage patterns (collocations) in English sentences.

Final Answer:
The correct verb to complete the sentence is commended.
