问题     Given the advantages of electronic money, you might think that we would move quickly to the cashless society in which all payments are made electronically. A true cashless society,【C1】________ , is probably not around the corner. For example, Business Week predicted in 1975 that electronic means of payment  "would soon revolutionize the very concept of money itself," only to【C2】________ itself several years later. Why has the movement to a(n)__【C3】________ society been so slow in coming?
    Although e-money might be more convenient and may be more efficient than a payment system based on paper, several factors work【C4】________ the disappearance of the paper system. First, it is very expensive to set up the computer, card reader, and telecommunications networks necessary to make electronic money the【C5】________ form of payment. Second, paper checks have the advantage that they【C6】________ receipts, something that many consumers are unwilling to give up. Third, the use of paper checks gives consumers several days of "float" — it takes several days before a check is cashed and funds are【C7】________ from the issuer’s account, which means that the writer of the check can earn interest on the funds in the meantime. They eliminate the float for the consumer【C8】________ electronic payments are immediate. Fourth, electronic means of payment raise security and privacy concerns. We often hear media reports that an unauthorized hacker has been able to access a computer database.
    Although a whole new field of computer science has developed to【C9】________ with security issues, a further concern is that the use of electronic means of payment leaves an electronic【C10】________ that contains a large amount of personal data on buying habits. There are worries that government, employers, and marketers might be able to access these data, thereby eating into our privacy.

解析 上下文题。根据词性，此处应当填入名词。可选范围是trail“痕迹”，path“路径”，lane“小路”，且根据上下文描述，电子付费方式存在的忧虑之一：会留下包含大量个人信息的痕迹。根据此语义阐释，故选trail。
