Yes. That is an advantage of a liquid fueled rocket.
On the other hand, a solid fueled rocket is simpler and therefore cheaper but once it is started, you have to wait until it burns itself out.

No, it worked as designed. While it didn't fly very high it did take off and fly as far as the propellant would carry it. This was the first successful flight of a liquid-fueled rocket.
The term 'rocket' is very General, the first recorded flying object to take off using rocket propulsion was either the Me-163 or the V-1 Doodlebug, both made in Nazi Germany.
A rocket in space can shut off its engines and still keep moving due to the principle of inertia. Once the engines are turned off, the rocket will continue to move forward at a constant velocity unless acted upon by another force, such as gravity or a change in trajectory.
An air-intake engine shut-off valve regulates air-flow to the motor, and operates as an emergency shut-off valve. There are also shut-off valves on water hoses, so shut-off valves really control the inflow of any liquid or gas.
There are two types of rockets -- those that use liquid fuel and those that use solid fuel. Liquid fuel rockets have two main advantages. Liquid fuel rocket engines burning can be controlled. That is, they can be turned on and off, and their thrust (pushing force) can be controlled/varied. Second, they produce more thrust for the same amount (weight) of fuel -- called specific impulse. Liquid fuel is also cheaper, but that's rarely a consideration as it is such a small part of the cost.
Liquid rocket engines would act much like a car engine. More fuel, more thrust. Solid rocket engines are either on or off. No throttle control.
The white stuff seen on the Saturn rocket at liftoff is ice that forms due to the extremely cold temperatures of the cryogenic fuels being used. As the supercooled liquid fuel oxidizes and burns, it creates water vapor that condenses and freezes upon contact with the cold rocket surface.
The Saturn V rocket used a liquid fuel system, with a combination of liquid oxygen (LOX) and RP-1 (a refined form of kerosene) as its propellants for the first stage. This combination provided the necessary thrust to lift the massive rocket off the ground and into space.
Ice accumulates on the (orange-brown) external fuel tank for the Space Shuttle because it contains very cold liquid hydrogen and oxygen (fuel for the shuttle engines). Although the tank has foam insulation, it needs to be lightweight and so it can only be partially effective in preventing condensation. Water condenses out of the air and freezes in some locations around the fuel tank.
The purpose of the fridge shut off valve is to control the flow of gas or liquid to the refrigerator. It functions by opening or closing to allow or stop the flow of the gas or liquid, regulating the amount that enters the refrigerator to maintain the desired temperature.
A solid fuel rocket engine is just what it sounds like. The fuel inside the rocket is completely solid. In a liquid fuel rocket the fuel is a liquid. Bottle Rockets that you can buy in many stores are fueled with Solid Fuel. Most liquid fuel rockets contain 2 different types of fuel. Once that fuel is mixed and ignited you get your thrust.
