Question: How to make sure all the clocks in the house are set accurately?

  Options: 
 A. Get a solar clock for a reference and place it just outside a window that gets lots of sun. Use a system of call and response once a month, having one person stationed at the solar clock who yells out the correct time and have another person move to each of the indoor clocks to check if they are showing the right time. Adjust as necessary.
 B. Replace all wind-ups with digital clocks. That way, you set them once, and that's it. Check the batteries once a year or if you notice anything looks a little off.
Answer: B
