A postal company observed that some of their packages to a certain destination were not delivered on time. It is known that a nearby airport had issues with its baggage handling system行李处理系统, leading to passenger luggage delays. The postal company suspects that the airport's problems caused the delay in their package deliveries.
Which of the following, if true, would most strengthen the postal company's claim?
A) The airport in question is the only one in the region that handles both passenger luggage and postal packages.这个选项说明了机场处理包裹的独特地位,意味着任何机场行李处理系统的问题都直接影响到邮政公司的包裹交付。
B) The postal company had recently increased the volume of packages sent to this destination.增加包裹了也不能说明是航空公司的问题。
C) Other postal companies using the same airport also reported similar delays in their package deliveries.其他邮司的问题和我的问题的因无绝对关系。
D) The airport's baggage handling system was known to be inefficient even before the recent issues.之前就有问题了和现在不成绝对关系。
E) The postal company had an exclusive contract with the airport for all package deliveries to that destination.独家签署说明只能是航司问题,正确。独家合同表明邮政公司依赖该机场进行包裹交付,但并没有直接指出机场问题是导致延迟的原因。
"Goats have been infected with a virus that can be transmitted through physical contact. The government claims that cattle will not be infected by this virus, citing a previous case where hogs were infected with a different virus and no cattle were infected despite predictions. What statement, if true, would most weaken the government's claim that the virus affecting goats will not be transmitted to cattle?"
山羊有病但不感染牛——因为有病的猪不感染牛——削弱羊不感染牛
A) Cattle and goats are often kept in close proximity, unlike hogs and cattle.离得近就一定会被感染吗?未说明这个选项直接指出了牛和山羊之间的密切接触可能性,这增加了病毒传播到牛的可能性,直接削弱了政府的声明。
B) The virus infecting goats has been proven to be more contagious传染的 than the one affecting hogs.羊比猪得的病更有传染性但是万一牛是免疫这个病的呢,可能依旧不被感染。但它没有直接涉及到牛和山羊之间的传播。
C) There are documented cases of cattle being infected with similar viruses in the past.和羊的关系呢?
D) The virus affecting hogs was found to be non-contagious没传染性的 to all other animal species.说明牛还是有可能被其他渠道传染的,只是猪不传染而已。说明了另一个病毒的非传染性,但并不直接影响关于当前病毒的讨论
E) Goats and cattle have similar immune systems, making transmission of the virus more likely.
只是更有可能,万一根本不让她们接触的话还是传染不了。 |
