Two platoons line up for a tug of war. if both platoons have the same number of participants on a team, what other factor is critical to either platoon's win? a) age of men b) height of men c) total mass of the team d) condition of the ground

The best answer is C) total mass of the team. 

In tug of war, the mass of each team is a critical factor in determining which side wins. The team with greater mass will require greater force to move, and also is likely able to exert greater force on the other team due to the correlation between strength and mass.
