A.I. Explanation:

Option 1: "To reduce operational costs"

Explanation: The text does not mention reducing operational costs as a goal of the four-day workweek. Instead, it focuses on improving employee wellbeing and work-life balance, indicating that cost reduction is not the primary aim.

Option 2: "To increase the number of working hours"

Explanation: This option contradicts the text, which states that the company is transitioning to a four-day workweek, implying a reduction in working hours rather than an increase. The aim is to enhance employee satisfaction, not to extend working hours.

Option 3: "To improve work-life balance and employee wellbeing"

Explanation: The text clearly states that the initiative aims to improve work-life balance and employee wellbeing. It highlights the benefits of a four-day workweek, such as reduced stress and enhanced job satisfaction, which directly supports this option.

Option 4: "To implement a temporary work schedule"

Explanation: The text indicates a permanent transition to a four-day workweek rather than a temporary schedule. This option misrepresents the company's commitment to a long-term change aimed at improving employee happiness and productivity.
