Which word can also mean 'an obligation, engagement, pledge or understanding'?

• A. Obligation
• B. Pledge
• C. Agreement
• D. Commitment

Answer: (D)

This item tests how a single word can carry multiple related ideas—an obligation, an engagement, a pledge, or an understanding. The best choice is the word commitment because it naturally conveys all of these senses. You can talk about a commitment as an obligation you owe or a duty you’ve agreed to fulfill, as a strong engagement to a project, person, or cause, and as a pledge you’ve made to act in a certain way. It also captures an understanding between people or groups that there is a mutual obligation to follow through.

For example, a person might say they have a deep commitment to their family (engagement and obligation), or that their commitment to the project means they’ll see it through (obligation and engagement). A company might emphasize its commitment to a charity (pledge) and to long-term collaboration with partners (understanding/consensus). Other options miss at least one of these senses: obligation focuses on duty but not the pledge or engagement; pledge is a promise but doesn’t inherently cover ongoing obligation or mutual understanding; agreement is a negotiated deal but doesn’t imply personal vow or ongoing commitment.
