Answer:
Oxygen
Explanation:
Oxygen is a nonmetal element. We wouldn't be able to breathe air because of all the toxins, it's just like smoking.
Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).
Hi, I'm pretty sure that is because for many slaves, Canada represented a dream of freedom where slave catchers and lynch mobs couldn’t hurt them. Slaves on the Underground Railroad endured months, and even years, of living like fugitives while bounty hunters and racist government policies were always trying to impede their flight to freedom.
Most slaves started out their journey on the Underground Railroad (which wasn’t an actual railroad but more of a resistance and escape route that was heavily organized by concerned American citizens) by running away from their plantation in the middle of the night. Often the runaway slave was alone, but on many occasions whole families would escape together.

Explanation: Radar and Enigma were two technological devices used during world war II. Radar works by sending out a signal in the form of a pulse, and any object within range of the radar dish will come into contact with the pulse, and return it back to the dish, registering it on the monitor.
Radar played a pivotal role during the Battle of Britain and the blitzkrieg of London. Due to radar capabilities, the Royal Air Force (R.A.F) was able to detect in coming Luftwaffe (German Air Force) planes. The R.A.F was then able to scramble their planes and alert nearby target areas and this enabled them to hold off the German advances, preventing an amphibious assault of the island.
The Enigma machine was a communication tool the Nazis used during World War 2. It encrypted and decoded messages being sent between the Nazi positions. The Enigma aided the Nazis in ocean warfare, as the German ships could easily communicate with each other around the Allied ships. The Enigma code was only broken when the British Navy was able to capture a damaged U boat before it could sink, and subsequently captured the Enigma machine and the code books, turning the tide in the Allieds' favour.
