During the Second World War, the Final Solution was a plan of Nazis for the genocide of Jews population. The "Final Solution to the Jewish question" was a code for the mass slaughter of all Jews within the reach of the Nazis. This solution was not confined to the European continent.

As a result of this solution, the world witnessed the mass killing of 90 per cent of the total Jews population.
Answer:
Gear a
Explanation:
Gears are pairs of rotating elements which transmit torque to the one another. Each gears have teeth on them and they mesh together to transfer rotary motion from one shaft to the the shaft. Gears can change the power, speed and the direction of power source.
In the context, it is given that gear a is the driving gear. If the gear a meshes with gear b, gear a will rotate gear b. Hence gear a is the driving gear and gear b is the driven gear. Thus gear b gets its motion from gear a.
Now if the teeth of gear b are sheared, then gear b will not be able to mesh with gear a and thus gear b ceases to stop its motion.
Thus gear a will turn.
