What is a tool used to shoot projectile by burning gunpowder?

• A. Firearm
• B. Bullet
• C. Powder
• D. Primer

Answer: (A)

The main idea is that a firearm is the device that uses the burning propellant to propel a projectile. In firing, the primer ignites the powder, quickly generating high-pressure gas that pushes the bullet down the barrel and out of the gun. The bullet is the projectile that is shot; the powder is the propellant that provides the energy; the primer is the small explosive that starts the burn. So, the firearm is the tool that makes shooting possible, while the other items are components involved in the process.
