Idioms – Choose the option that best explains the meaning of the highlighted expression in context. Sentence: When he heard that he had once again not been selected he “lost heart.”

Introduction / Context:
The idiom “lose heart” refers to a loss of courage, confidence, or hope, especially after repeated setbacks. In the sentence given, not being selected “once again” signals discouragement rather than a single moment of sadness or anger.

Given Data / Assumptions:

• Key phrase: “lost heart.”
• Background: repeated failure to be selected.
• We must choose the meaning that stresses diminished resolve.

Concept / Approach:
While sadness and anger are emotional reactions, “lose heart” specifically targets motivation and perseverance. The best paraphrase is “became discouraged,” which captures the drop in morale and willingness to continue trying after disappointment.

Step-by-Step Solution:

Verification / Alternative check:
Substitute: “he became discouraged” reads naturally and preserves the motivational dimension of the idiom. Standard dictionaries gloss “lose heart” as “become discouraged.”

Why Other Options Are Wrong:

• became desperate: Suggests frantic action, not simply low morale.
• felt sad: Too mild and focused on feeling, not perseverance.
• became angry: Wrong emotional direction.

Common Pitfalls:
Equating discouragement with sadness. Discouragement affects future effort; sadness may be momentary and not predictive of behaviour.

Final Answer:
became discouraged
