2020 Mock Exam B - Morning Session 第10题： 10 Using Exhibit 3 and Quinn’s reminder, the most appropriate measure of the accuracy of the model is: A 0.79. B 0.86.

2020 Mock Exam B - Morning Session 第7题： Wu’s recollection about the preparation of the textual data is most accurate with respect to: A numbers. B stop words. C lowercasing. 题目描述： Wu tells Quinn that she has heard a little about text mining for clues about an individual’s behavior and recalls that text preparation must be carried out by removing such items as HTML tags, punctuation, numbers, and stop words and eliminating the distinction between uppercase and lowercase words by lowercasing them all. 这道题不是问正确的做法吗， 为什么选A呢？ A numbers. ——不是应该在去掉后增加注释才正确吗？ B stop words、C lowercasing——这两步应该是“数据处理”过程里的动作，不是“数据准备”里的动作，是这个意思吧？
