Explanation:

Question 10

Step1: Analyze each option

• Removing all light - bulbs and having employees use battery - powered flashlights would be very inconvenient for employees and disrupt their work.
• Turning off heat/air systems and unplugging electrical items when the office is closed is a good energy - saving measure with no negative impact on employees during working hours.
• Replacing a microwave with a charcoal grill is not practical (charcoal grills are not suitable for office breakrooms in terms of safety, cleanliness, and convenience).
• Going paperless on Tuesdays is a limited measure and may not be the most effective in reducing overall energy usage compared to other more comprehensive non - disruptive measures.

Step1: Analyze each option

• Using public transportation reduces the number of individual vehicles (which consume energy) on the road. Developing more efficient vehicle engines means less energy is used per vehicle.
• Turning thermostats down in winter (so less energy is used for heating) and up in summer (less energy for cooling) saves energy.
• Insulating homes and businesses reduces the need for excessive heating or cooling (as heat transfer is minimized), thus saving energy.

Since all of these actions contribute to reducing energy waste (by either reducing energy consumption directly or making energy use more efficient), the option “All of these are ways which we can lower energy waste” is correct.

Answer:

remove all the light bulbs in each office and allow employees to bring battery - powered flashlights
