(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. At first, their use was limited to wealthy people. Over time, however, they became ( 22 ). 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. ( 23 ), it seems as though societies will continue to use cash. 1 can be lost or stolen can be recycled 1 thinner and lighter 3 harder to use 1 For now 2 Until then 2 4 2 4 3 is used for shopping online is understood by almost everyone more colorful and exciting more widely available With luck 4 By contrast

文構造について質問です！ catch a picture で「姿をとらえる」ですか？？ これってどういうイメージで覚えればいいんでしょうか？？

第6段落 ¹Awareness of touch can bring a new feeling to the most commonplace experiences. 2“I have just touched my dog," wrote the young Helen Keller in her diary. 3"He was rolling on the grass with pleasure in every muscle and limb. 4I wanted to catch a picture of him in my fingers, and I touched him lightly as I would cobwebs. 5But, to my surprise, his body turned towards me and moved into a sitting position, and his tongue gave my hand a lick. He pressed close to me as if he intended to put himself into my hand. He loved it with his tail, with his paw, with his tongue. If he could speak I believe he would say with me that paradise is attained by touch."
