A new study finds that blacks on death row (1) of killing whites are more likely to be executed than whites who kill minorities. It also concludes that blacks who kill (2) minorities are (3) likely to be executed than blacks who kill whites. For example, there is more than a twofold greater risk that an African-American who killed a white will be executed than a white person who kills a (4) victim. A Hispanic is at least 1.4 (5) more likely to be executed (6) such an offender kills a white.
The researchers of the study believe that there are two (7) explanations.. First, prosecutors often win (8) office if they win well-publicized cases. When a black kills a white, such killings gets more (9) and this idea can be (10) by many famous cases. (11) , the court judges at the state level are often (12) to elections, called retention elections.

Just as the researchers (16) out, death penalty is (17) political.
The findings of the study, in short, show that American justice systems clearly (18) white lives more than those of blacks or Hispanics. The researchers also say their findings (19) serious doubts about (20) that the U.S. criminal justice system is colorblind.

参考答案：A
解析：
[考点] 语义理解+词义辨析
本题考查词义辨析。A选项support表示“支持、支撑”不光用于具体意义，也常用于抽象意义，也就是说support的主语和宾语可以是人，也可以是抽象的东西。本题的意思是说，这一idea得到了很多case的支撑，换成主动句式，“很多案件都支撑了这一观点”。所以选项A为正确答案。
[干扰项分析] 首先从词性上看，选项D为动词原型(也可作名词)，而其他三个选项都为过去分词。空格前有be,显然后面不能跟动词原型，倘若当名词讲，意义也不通，所以首先排除选项D。选项B、C均表示“批准、认可”，区别不大，换句话说，选B就能选C，这与完形填空的单项选择要求不符合。另外，approve这一单词也在考试中多次出现，而且常是学生的首选。学生选错的原因很简单，混淆了两个形近词：prove，approve，前者是证明的意思，而后者是批准的意思。
