Q7: (题有点没读懂，是不是3个队，各出3人比赛。9个人比赛，取前5名阿？)

For a certain race, 3 teams were allowed to enter 3 members
each.  A team earned 6 – n points
whenever one of its members finished in nth place, where 1 ≤ n ≤ 5.  There were no ties, disqualifications, or
        withdrawals. 
If no team earned more than 6 points, what is the least possible score a
team could have earned?

A.    0

B.     1

C.     2

D.   
3

E.     4

意思是有3个队，每个队派3个人，一个队员赢得了第n名，这个队就获得6-n分，现在没有一个队获得超过6分，问一个队最少可能得几分
