Using a simple pulley and rope system, a crewman on an Arctic expedition is trying to lower a crate of mass \( m_{1}=5.00 \mathrm{~kg} \) to the bottom of a steep ravine of height \( H=25.2 \mathrm{~m} \). The crewman has a mass of \( m_{2}=5 \mathrm{~kg} \). How can the crewman successfully lower the crate?
A) By using a more complex pulley and rope system
B) By increasing the mass of the crewman
C) By decreasing the mass of the crate
D) By increasing the height of the ravine
