Original sentence: Some people have suggested that the American government engineered the events so that they could attack Afghanistan for its gas and attack Iraq for its oil.Such controlled demolitions can take up to two months to plan.The official reports claim that the Twin Towers fell because the force of the jets and the fire weakened the steel.This has suggested to some that explosives were used and had been placed on every floor near all the steel joints of the building before September 11th.This is because they fell straight down almost as fast as gravity, with each floor showing little resistance
