What is the minimum number of wins with which a person can advance from the 1st module to the second module?
Total number of face-offs are 8C2=28. If the highest number of wins in module 1 is 7, then the other person advancing to the next round can win 3 face-offs and qualify. The remaining people can also win 3 face-offs each; totaling to 7+(7*3) =28 face-offs. If 7 members win 2 face-offs, then the total number of points do not add up to 28. Hence, answer is option (c)
