A.I. Explanation:

Option 1: "bad for the organisation"

Explanation: The text concludes with the statement that wasting time and energy is 'bad for the organization.' This aligns perfectly with the overall theme of the text, which emphasizes the importance of targeted hard work to avoid wasting valuable resources. The phrase 'bad for the organization' is a direct paraphrase of the text's conclusion, making it the correct choice.

Option 2: "the target of every organisation"

Explanation: This option suggests that hard work is the goal of every organization, which contradicts the text's message. The text argues that hard work must be properly targeted; otherwise, it becomes wasteful. Therefore, this option does not align with the text's main idea.

Option 3: "helpful for any organisation"

Explanation: While hard work can be beneficial, the text specifically states that it is only valuable when properly directed. This option implies that hard work is always helpful, which is too broad and does not reflect the text's caution against misdirected efforts.

Option 4: "liked by organisations"

Explanation: This option implies a positive sentiment towards hard work without addressing the necessity of its proper targeting. The text indicates that hard work can be detrimental if not focused correctly, making this option inconsistent with the text's argument.
