They spent two weeks【C3】________ yoghurts and similar foods, like cheese. Researchers then【C4】________bacteria levels and odour-causing compounds, including hydrogen sulphide.
The volunteers then ate 90 grams of yoghurt a day for six weeks. At the end of the study, researchers took【C5】________ again. They found hydrogen sulphide levels decreased in 80% of participants.

解析
空格位于修饰主语volunteers的定语从句中,该从句缺谓语,且空格后有介词in,故此空应填不及物动词:再根据主句的时态(were given…),可知空格处应填入动词的过去式。词库中符合这一要求的只有participated“参与”。代入后表示“这24名志愿者就是参与了该项研究的被试对象”,符合句意。
