請問B、C如何判斷?我沒有辦法把這兩個選項跟文章串起來,看不出他們有什麼關聯😭

女大考三題型 Unit 8 The Risks of Bio-terrorism In 2001 a number of US government employees and citizens died, after opening 1 letters deliberately contaminated with a deadly disease. 2 The government has responded to the threat by introducing a "Bio-Watch" system, which uses special equipment to detect unusual organisms in the atmosphere. Nevertheless, it can provide an early warning system for major towns and cities, allowing medicine to be rushed to an area under attack. 3 However, the US government is much more worried about the psychological impact, rather than the actual death toll, of a bio-terrorist attack. Any disease effectively released as a bio-weapon in a highly populated zone could cause general panic. 4 As a result of the continuing bio-terror threat, the US government is trying to make its citizens more confident that it can combat this menace. By doing so, it hopes that there will be less widespread panic. Therefore, if a major bio-attack occurs, people can take immediate action to minimize the damage. (A) This was probably the work of a mad scientist, but it signaled to all Americans that bio-terrorism was a clear and present danger. (B) This might freeze normal economic activities in the world's biggest economy center, and thus cause chaos in the global financial system. (C/Infected people can then be treated, and most will survive. DUnfortunately, this technology cannot filter the mail or prevent terrorists releasing diseases in enclosed places. 1. 2. y 3. C 4.
