Completing the Sentence on Happiness

The sentence requires a word that describes the state of being happy due to satisfaction with one's current situation.

The key phrase is "satisfied with what they have," which directly links to the cause of their happiness.

Analyzing Word Choices

• Contentment: This word means a state of peaceful satisfaction. It perfectly matches the description of being happy because one is satisfied with their existing possessions or circumstances.
• Ambition: This refers to a strong desire for success or achievement, often implying a need for more, which contrasts with satisfaction.
• Perseverance: This means continuing firmly despite difficulties. While valuable, it doesn't directly explain happiness derived from satisfaction with what one *has*.
• Hunger: This implies a strong need or desire, often for something lacking, which is contrary to the idea of being satisfied.

Therefore, Contentment is the most appropriate word because it directly signifies happiness stemming from satisfaction with one's current state.

The completed sentence reads: Contentment is the key to their happiness; they are satisfied with what they have.
