Ⅰ 次の英文を完成させるために,空所に入る最も適切な文を(A)~(D) より選び、その記号をマー クせよ。 ( ) He describes it is a state of ideal experience that can be brought about by tasks that have clear goals and provide immediate feedback. ack() Chess and basketball players, dancers, climbers, and assembly line workers can all experience flow while deeply engaged in their activities. Flow happens at a point of balance between boredom and frustration. (3) On the other hand, if the challenge is too high relative to the individual's skill level, frustration becomes likely. The flow state sets in when the challenge level of the activity meets the skill level of the person. In this sense, flow is related to what we call "fun." () For example, climbers will move on to ascend more demanding rock formations, and chess players will seek to play against more skillful opponents. ✓ (A) One of its defining characteristics is the loss of the sense of self and time because absorption in the task at hand is so complete. (B) Flow, as famously investigated by Mihaly Csikszentmihalyi, is a mental state characterized by deep absorption during challenging activities. (C) Moreover, as our skills improve in the activity, we seek to increase the challenge in order to keep experiencing flow. (D) If an activity provides a level of challenge that is too low relative to the skill level of the person, it becomes boring,

(21)の答えが3になるのがなんでか少し分からないです…わかる方いますか？？

(21) (22) (23) Any Change? Long ago, humans did not use money. Because they often could not produce everything that they needed, they traded some of their goods for goods made by others. Gradually, the goods that they exchanged were replaced by cash. For hundreds of years, metal coins and paper bills that can be exchanged for goods and services have been produced. Cash is convenient for many people because it is easy to carry. At the same time, though, it ( 21 ). Another disadvantage is that criminals have been able to produce fake coins and bills. In the middle of the 20th century, plastic credit cards were introduced. They had security features to prevent them from being used by anyone except their owners.

In the last few years, apps for smartphones that can be used in the same way as credit cards have also become popular. Because of this, some people are suggesting that we may soon see the end of cash. Supporters of a "cashless" society in which all payments are made electronically argue that it would have several benefits. For example, people would not have to worry about keeping their wallets safe. However, some people are concerned that they might be unable to pay for the things they need because of a software error or a broken smartphone. Moreover, some people do not have bank accounts or credit cards, so their only option is to use coins and bills.
