Answers:
I. The Scientists and the Watches
1. The two scientists were arguing about whose watch was better.
2. They couldn't continue the experiment because there was something wrong with
both watches.
3. They observed the watches for a couple of hours without speaking.
4. They realised the Swiss watch was losing sixty minutes an hour.
5. (b) if a watch is losing sixty minutes in sixty minutes, it's stopped.
6. (a) Once in every twelve hours the Swiss watch would show the right time.
7. The Japanese watch was losing 120 minutes every sixty minutes.
8. (с) It is going backwards if it loses 120 minutes every sixty minutes. In other words,
every time a clock telling the correct time moved forward an hour, the Japanese clock
moved back exactly an hour.
9. The Japanese watch will show the correct time twice in every 12-hour period, i. e.,
every six hours.
10. The scientist with the Japanese watch was right when he said, "My watch is right
more often than yours."
11. Neither watch tells the correct time - they only show it. You wouldn't know they
were showing it without a third watch to refer to.
