Until relatively recently, people in some parts of the world continued to use salt as a form of cash. There are several reasons why salt was used as money. Salt was given an economic value because there were so few places that produced it in large quantities. ①Another reason is that salt is fairly light and easy to carry for trading purposes. ②Additionally, salt can be measured, so we can easily calculate its value based on its weight. ③Furthermore, salt stays in good condition for a very long period of time, so it holds its value. ④Last but not least, salt has many other uses such as melting ice on roads in snowy regions. In short, salt has certain characteristics that make it suitable as a form of money.
問3 [ 31 ]
In the past, most Japanese TV shows started and ended exactly on the hour. ①While TV shows vary from station to station, on the whole, early morning hours are dominated by news programs and evening hours by variety shows. ②Because of competition, some networks tried to gain an advantage over their rivals by starting their programs a little earlier. ③Many people start channel surfing near the end of a program, and the networks thought that if their show started a couple of minutes earlier, people would start watching it. ④Another strategy was to end a popular show a little after the hour so that people would stick to one channel and miss the beginning of shows on other channels. Now that many stations have adopted these strategies, the advantage for any one station is lost. Even so, they continue this practice because they are afraid of losing viewers.
