17)An American nightclub called 'The Coconut Grove' had a terrible fire in which over 400 people died. A simple design flaw in the building construction ,that made escape difficult,led to the death toll being so high. Subsequently, regulations were changed to ensure that all public buildings throughout the country eliminated this one detail which proved so deadly. What was it?

25)The main moving element is a piston, housed inside a cylinder. Inside the cylinder, there is a small spring. To operate the pump,you pull the trigger back, pushing the piston into the cylinder. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the cylinder. The downstroke, the piston pushing in,shrinks the area of the cylinder, forcing X out of the pump. The upstroke, the spring pushing the piston back out, expands the cylinder area, sucking X into the pump. The X must move through the pump in only one direction.What are we talking about?
