A.I. Explanation:

Option 1: "makes people work even harder at difficult tasks."

Explanation: This option is incorrect because the text discusses how learned helplessness leads to a feeling of helplessness rather than increased effort. The speaker indicates that individuals, like the child in the example, stop trying to improve their situation, which contradicts the idea of working harder.

Option 2: "stops people repeating positive experiences."

Explanation: This option is incorrect as the text does not mention anything about learned helplessness preventing the repetition of positive experiences. Instead, it focuses on how individuals feel helpless and stop trying to change their negative situations.

Option 3: "causes people to lose hope in their abilities."

Explanation: This option is correct because the text illustrates that learned helplessness leads individuals, such as the child in the example, to feel that their actions will not affect their performance. This loss of hope in their abilities is a direct consequence of learned helplessness, as they begin to believe they cannot change their circumstances.

Option 4: "affects people in many unpredictable ways."

Explanation: This option is incorrect because the text does not support the idea that learned helplessness has unpredictable effects. Instead, it clearly outlines a specific pattern of behavior and emotional response, such as the consistent feeling of helplessness in the face of challenges.
