选项 A、kind
B、type
C、form
D、category
答案 C
解析 此题为词汇辨析题。此处文义为：科学家认为以简单的数学形式发射的信号可能会易懂。A) kind 表示种类，其确切含义为“A group of individuals linked by traits held in common．(同种，同类因具有共同的特性而联系在一起的个体的集合。)”，而不是表示形式。B) type 的意思是“A number of people or things having in common trails or characteristics that distinguish them as a group or class．(类型一定数量的人或事物，具有把他们与一个集体或种类区分开的共同特征或特点。)”，也是表种类，而非形式。C) form 的意思是“The mode in which a thing exists，acts，or manifests itself．(形式，某物存在、运作、显现的方式。)”，例如：a form of animal life (动物的生活方式)；a form of blackmail (恐吓的方式)。符合上下文，为正确答案。D) category 的含义是“A specifically defined division in a system of classification；a class．(种类在某一分类系统中特别定义的部分；类别。)”，也是表类别，而非形式。
