[求助]XDF上的逻辑104题和106题

请NN帮忙指点一下, 在此先谢谢了!

104.There are fundamentally two possible changes in an economy that will each cause inflation unless other compensating changes also occur. There changes are either reduction in the supply of goods and services or increases in demand. In a prevanking economy the quannity of money available, and hence the level of demand, is equivalent to the quantity of gold available.

If the statements above are ture, then it is also true that in a prebanking economy

B)  if other factors in the economhy are unchanged, increasong the quantity of gold available will lead to inflation.

C)  if there is a reduction in the quantity of gold available, then, other things being equal, inflation must result.

觉得这两句内容差不多, 只是方向相反. 我选C, 但不知为什么答案是B?

106.In the United States, injuries to passengers involved in automobile accidents are typically more severe than in Europe, where laws require a different kind of sagety belt. It is clear from this that the United Stated needs to adopt more stringent standards for safety belt design to protect automobile passengers better.

Each of the following, if ture, weakens the argument above EXCEPT:

D)  Automobile passengers in the United States have a greater statistical chance of being involved in an accident than do passengers in Europe.

E)  States that have recently begun requiring the European safety belt have experienced no reduction in the average severity of injuries suffered by passengers in automobile accients.

不知该如何判断? 看不出哪个有关或无关?

104. 我估计是判断哪个是supply，哪个是demand是这题的关键吧。题目说了通货膨胀可能发生的条件，需求增加，或者供应减少。B正好是符合这个规律。C里面，gold是demand，减少gold，等于是减少了需求，所以不会造成通货膨胀。

106. 我选的是E。 E 是削弱。因为有些州已经用了新的safety belt，但是事故率没有怎么下降，从而削弱了题目里面要求USA改用新safety belt的建议。D由于没有提到事故率高和严重事故的关系，也没有解释为什么safety belt的建议不具有说服力，所以我觉得不是选项。

你认为呢？
