Which of the following is an example of the third form of cooperation as it is defined in Paragraph 4
A．Students form a study group so that all of them can improve their grades.
B．A new business attempts to take customers away from an established company.
C．Two rival political parties temporarily work together to defeat a third party.
D．Members of a farming community share work and the food that they grow.
参考答案：C
解析：[分析] 细节题型。 见第四段第一句和第三句：In the third type，called tertiary cooperation or accommodation，latent conflict underlies the shared work．．．Accommodation involves common means to achieve antagonistic goals；it breaks down when the common means cease to aid each party in reaching its goals．第一句谈到：在第三级合作或迁就融合性合作中，在共同参与的工作背后存在着潜在的冲突。而第三句谈到：迁就融合性合作包括采用一致的手段去达到敌对的目的；而当一致的手段无法使得各方达到自己日的时，这种合作就破裂了。内容与选项C．“两个竞争的党派会为了击败第三个党而暂时合作”相符，所以C正确。
