单选题1：Researchers in the social sciences may often have ( ) their scope to those narrowly circumscribed topics that are well suited to quantitative methods.
A. diminished B. enlarged C. limited D. expanded
答案：C
避坑解析：易错选A，题干后半句“narrowly circumscribed topics”提示范围是被“限制”，而非单纯“缩小”，limit更贴合学术研究语境的搭配逻辑。
单选题2：With the constant change of the conditions, the outcome is not always ( ).
A. favorable B. predictable C. dependable D. reasonable
答案：B
避坑解析：易错选C，dependable侧重“事物本身可靠”，而题干强调环境变化下结果无法被预判，predictable才符合语义逻辑。
单选题3：After a concert tour in Asia, England and Canada, he will ( ) work on a five-language opera.
A. confine B. indulge C. resume D. undergo
答案：C
避坑解析：易错选A，confine后需搭配to表示“局限于”，题干表达巡演结束后“重新继续”歌剧创作，resume完全贴合语境。
