When classifying 700 audio samples, the system got their emotional sense right 72 percent of the time. A group of 138 people working on the same clips【C4】________60 percent accuracy. The software was also much better than the humans at recognizing which clips it couldn’t classify【C5】________. When allowed to skip these clips, the accuracy rose to 85 percent.

选项
答案 M
解析 形容词辨析题。空格位于不定冠词a之后，名词comparison之前，应填入形容词。人类与软件在识别语言中的情感方面，对比情况如何应看空格所在句之后的内容。第二段第二、三句提到软件识别正确率为72％，而人类的正确率只有60％，可见对比明显，而与此意相近的只有M)robust“强有力的”。
