Which of the following logically completes the reasoning in the passage?

The Roman emperors issued coins made of silver-copper alloy. Over time the silver content in the alloy used for minting was reduced from an original 90% to less than 10%. The coins, however, continued to appear silver on the outside. It is therefore tempting to suspect that the silver surfaces were added to hide the reduction in silver content. However, that suspicion is probably groundless, since_________.

A surviving late Roman coins that are much worn often do not appear silver at all.

B the Roman emperors were increasingly unable to afford to maintain a high silver content in their coins.

C in Roman times it would not have been possible to analyze the exact proportions of the metals in a coin once it had been minted.

D most members of the public were probably unaware of what the coins looked the inside.

E Roman metalworking methods of the time would have naturally resulted in a thin silver layer on the surface of any silver copper alloy.

Criminologists studying public perceptions of crime versus actual crimes reported by police found that, in countries worldwide, most people think violent crime accounts for a much larger percentage of the total crimes than it actually does. The criminologists hypothesize that these estimates are caused by media misrepresentations, noting that violent crime is depicted prominently in many countries' most popular media, like television shows and books, while other types of crime are underrepresented or not depicted at all.

Which of the following would it be most useful to determine in evaluating the criminologists’ hypothesis?

(A) Whether greater exposure to media correlates strongly with higher estimate by the public of the violent crime rate

(B) Whether countries in which people watch more television also have higher violent crime rates than other countries do

(C) Whether people in countries worldwide perceive violent crime differently when they read about it than when they see it on television

(D) Whether certain television shows that prominently feature violent crime are available in more countries than they used to be

(E) Whether media in countries worldwide misrepresent violent crime to the same degree

1、现象：硬币中银的含量从90%下降到10%，但是仍维持银色外表。原因：不是由于故意在表面涂银来隐藏减少银含量。问explain
思考：解释造成银色外表的原因不是故意在表面涂银。

A：幸存的晚期罗马硬币磨损很厉害，外表几乎没有银了。反向反了，那就更说明是表面涂了银。
B：罗马统治者无法支付这么高的银含量了。解释前提。
C：罗马时期无法测量银含量。无关。
D：公众不知道硬币里面长啥样。无关，如果相关也是相反。
E：当时的铸造技术会让银在表层。正确，不是故意，而是技术造成的。

选E

2、现象：公众认为的暴力犯罪率比实际要高，原因：媒体误导。
问evaluate
思考：是否有他因削弱，同因反果同果反因，因果倒置，或者削弱因果联系。

A：是否媒体披露得越多，公众估计的暴力犯罪率就越高。正确，加强因果联系。
B：是否看电视越多，暴力犯罪率越高。是要探讨看电视和预估率的区别，而不是真实的犯罪率。
C：读和看会不会有区别。对比维度无关。
D：一些以报道暴力犯罪为特色的电视节目是否比过去更容易看到。过去与现在的对比维度无关。
E：全世界的媒体是不是误导程度都一样。对比维度无关。

1. Strengthen E
R用S-C合金做银币，一段时间后S含量从90%减少到了10%，但硬币表面看起来还是S的。因此S表面掩盖了S含量的减少。【然而，结论】S表面不是为了掩盖S含量减少 因为？       
E R制作金属的方法就导致所有S合金表面都说薄薄的S layer 说明不是为了掩盖S含量少了       
2. Evaluation A
许多人认为violent犯罪占比很大，超过实际占比。犯罪学家就认为这是因为媒体的误导。
A 取反，如果媒体对公众认知没有影响则削弱
