Correct Answer:
Option A. Influenza
During 1918 - 1919, an influenza epidemic killed about more than 20 million people. This epidemic killed more people than were killed due to the World War 1 and is said to be the most devastating epidemic of the history. Among the US troops which were deployed in Europe, more than half of deaths were a result of influenza rather than the killings done by enemy.
The correct answer is - Continental Polar air masses.
The Continental Polar air masses which are dry and very cold, are forming above most of what is the mainland of the country of Canada. These air masses are able to reach the Gulf of Mexico, and thus Texas, with ease, and very quickly, because they can move freely through the plains that stretch through the central part of the continent and there's no obstacle that will stop them or make them move to another direction. The Continental Polar air masses bring sudden cold and dry weather, and they are the most active from late autumn to early spring, being the most intense during the winter.
