Background Paragraph: Antifreeze could also be called “antiboil” because it also raises the boiling point of the water in a car radiator. Hot weather combined with a hot engine can easily raise the temperature of the water in the radiator above 100 °C, which is the boiling point of pure water. If the water boils, it could cause the engine to overheat and become seriously damaged. However, if antifreeze has been added to the water, the boiling point is much higher. For example a 50 percent antifreeze solution has a boiling point of 129 °C. Unless the water gets hotter than this, it won’t boil and ruin the engine. 
Story: Rob is an auto mechanic. He was checking the radiators of his car and truck. He put antifreeze into the car radiator, but didn't put any antifreeze into the truck radiator. He was wondering how the vehicles would fare in coming hot weather.
Which radiator's water would have higher boiling point, car or truck? Which radiator's water would have lower boiling point, car or truck? Which vehicle would do better in hot weather and hot engine, car or truck? Which vehicle would do worse in hot weather and hot engine, car or truck? Which vehicle's engine would less likely be damaged, car or truck? Which vehicle's engine would more likely be damaged, car or truck? Would the car's engine less likely or more likely be damaged than truck's engine? Would the car's radiator water have higher or lower boiling point than truck's radiator water? Would the trucks's radiator water have higher or lower boiling point than car's radiator water? Would the turck's engine less likely or more likely be damaged than car's engine?
