单选题
Some pundits are worried that these candidate Q-and-A sessions have
supplanted
regular newscasts with something less rigorous journalistically, but the carping seems misguided.
【正确答案】
B
【答案解析】解析：B项supersede“代替，取代”与画线词supplant“排挤掉，代替”的意思相吻合，如Will factory workers be entirely superseded by machines one day(工人将来能完全由机器取代吗)，故选B。A项succeeded“继……之后，继任，继承，取得成功”；C项distorted“扭曲，歪曲(真理、事实等)”；D项completed“完成，使完善”，均与画线词的意思不一致。
