Which term can be used to best describe the relationship between the underlined adjectives in "Unlike her gregarious sister, Jane is an unsociable person."?
A、Synonym
B、Antonym
C、Homonymy
D、Polysemy
【正确答案】：B
【题目解析】：反义词可定义为意义相反的词。题干中的例句：Unlike her gregarious sister, Jane is an unsociable person.（简不像她爱交际的姐姐，她是个不善于交际的人。）gregarious表示的是“善于社交的/爱社交的”，unsociable表示的是“不善于社交”，它们意思相反。
