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.

13（）
A.decide
B.expresses
C.makes
D.takes
参考答案：B
解析：
[考点] 语义理解+动宾搭配
首先分析句子结构，句中and前后各是一个部分。前半部分句子的主干就显现了：retention election is a periodic process。而and后面部分主句为a judge can be removed from the position，其后跟了一个if引导的条件状语。而express approval，make approval，take approval中，只有express approval(表示支持)是常用表达，英语中并无其他两个搭配。因此可以判断选项B正确。
[干扰项分析] 本题空格后面跟了宾语approval or disapproval，空格处需要一个动词，构成动宾搭配，因此要根据后面的宾语来确定动词。空格前的主语是the voter，那么空格处的动词应该是第三人称单数，所以排除选项A。
