Read the following paragraph and underline the TWO irrelevant sentences. 　Since the early 1930s, Swiss banks had prided themselves on their system of banking secrecy and numbered accounts. The aim of the agreement was to prevent the improper use of the country’s bank secrecy laws. Over the years, they had successfully withstood (经受) every challenge to this system by their own government who, in turn, had been frequently urged by foreign governments to reveal information about the financial affairs of certain account holders. The result of this policy of secrecy was that a kind of mystique (神秘性) had grown up around Swiss banking. There was a widely-held belief that Switzerland was irresistible to wealthy foreigners, mainly because of its numbered accounts and bankers’ reluctance to ask awkward questions of depositors. Also, they agreed not to accept funds resulting from tax evasion (逃税) or from crime. Contributing to the mystique was the views that if this secrecy was ever given up, foreigners would fall over themselves in the rush to withdraw money, and the Swiss banking system would virtually collapse overnight.
