Read the excerpt from the common sense of bicycling: bicycling for ladies.

there is a third movement of the handle-bars—a quick twist in the direction the machine is leaning if about to fall; it is made suddenly, and brings the wheel back to its original position. if the wheel were stationary, and the front wheel were turned, the bicycle would fall in an opposite direction from the front wheel. if the wheel is about to fall, it can be prevented from doing so by throwing the balance the other way by means of the handle-bars. a similar result is accomplished by wiggling the front wheel, and when a bicycle is moving very slowly, a continuous wiggle—changing the balance as the machine inclines from side to side—is necessary to keep it upright.

according to the excerpt, which steps are important to avoid falling off a bicycle?

releasing the handlebars and returning the wheel to its original position
using the handlebars to throw the balance and riding slowly
twisting the handlebars quickly and wiggling the front wheel
leaning in the opposite direction of the fall and keeping the wheel still
