3由同一已知事實可推出不止一個正確的結論。

　　例：Apart from the obvious fact that rioters tend to come from the less well-off section of the community, there is no evidence that economic circumstances have any causal relationship with street violence.

　　A) There is some evidence for relating economic circumstances to street violence.

　　B) Not all the people in the community referred to are poor.

　　C) There is no evidence that economic circumstances result from street viloence.

　　D) All rioters come from the poorer section of the community.

　　本例中，只有A可由原文推知，其中Apart from所引述的正是經濟環境與暴力的一種相關性;C否定了這一相關性，故與原文相悖;D與原句中“rioters tend to come from…”的原意不符：“往往”不等于“總是”;B則是原文第一部分的重述，不屬推論。
