题目要求是：for each of the following conclusions, select supported if it is supported by the information otherwise select not supported.
question2: Fewer than 25% of the respondents who believe a website could help expand their customer base also believe a website could help them maintain their current market share.
questions3: Only a small proportion of the respondents are concerned that they are losing market share.
Answer:
Q2: supported
Q3: not supported
对Q2，怎么看出来不足25%的认为website could help expand customer base的人同时认为website could help maintain current market share呢？我觉得maintai market share这个问题并不是仅仅对于认为website能expand customer base这一群人提出的，所以不能得出不足25%的持website could help expand customer base观点的人认为website could help maintain current market share.
对Q3，因为对于每一种族群都是只有大约4%-6%的人认为website could help preserve market share，所以表明大部分人都认为他们没有losing market share,支持了Q3 Only a small proportion of the respondents are concerned that they are losing market share. 为什么答案说not supported?
