Question 7:
Assume that:
All JUNS are TIFS                        
Some UMIS are HUNS                 
All DAES are HYNS
All TIFS are DAES
Which of the following is correct:
A: All DAES are HUNS
B: Some JUNS are DAES
C: All HUNS are HYNS
D: All JUNS are HYNS
E: Some JUNS are DAES

如果画完venn diagram，会有两个图， 第一个有umis 和huns， 可能huns会是完全在umis里， 也可能他俩有一部分相交。 但无论哪种情况不影响选哪个
第二图就是4个“同心圆“如果用圆来表示， 从里到外依次是， juns，tifs，daes，然后最大的圆是hyns
A， daes和huns没有任何一定的关系
B， 所有的juns都是daes
C， 如A
D, 正确， 从图看出juns一定是tifs， tifs一定是daes，daes一定是hyns
E， 所有的juns都是daes
