问题 Researchers have suspected that large portions encourage people to eat more, but studies have begun to______this suspicion only in the last several years.
选项 A、confirm
B、contend
C、contrive
D、concoct
答案 A
解析 句意：研究人员对食物份量大会促使人们吃得更多这一猜测有所怀疑，但是直到近几年来，研究才逐渐证实了他们这一怀疑。confirm认可；证实。contend虽有“主张；认为”的含义，但其后应接由that引导的宾语从句。contrive“设计，发明”和concoct“捏造；图谋”均不符合题意。故选A。
