The correct answer to this open question is the following.
Postwar anxiety increased in 1949 after a series of startling events showcased that the Cold War could be just as intense as a "hot" war. The events that occurred in 1949, causing the world to anticipate renewed military action were the following:
The signing of the North Atlantic Treaty Organization(NATO) in April.
The first detonation of an atomic bomb by the Soviet Union in the month of May.
Mao Tse Dong establishing the Communist government of the People´s Republic of China in October.
These events increased the tension in the so-called Cold War between the United States and the Soviet Union. These two superówers competed in the arms race, the space race, and the spread of Communism/containment of Communism, generating so much tension in the world.
They WERE sent to concentration camps during World War Two, so I believe it is True :) I hope this helps!
Agriculture is thought to have developed independently throughout the
world, so there is not necessarily one particular group of people that
could be considered to be the first. However, of the available options
the most likley to be correct would be a) Nomads in Central Asia. The
'fertile crescent' in the East is often referred to in this respect, as
being the first place agriculture was properly developed.
In the traditional Indian caste system, the people have been divided into multiple castes. Every caste was representing a certain level of hierarchy. The people born in one caste were destined to live in that caste until the end of their lives.
The communication between the castes was very obscure. Most of the communication was going on between members of the same caste, but rarely with members of other higher or lower caste. The members of the higher castes did not communicated with the members of the lower castes because they were looking at them as lower beings, so they did not wanted to have anything with them, and it was humiliating for them to communicate with someone that is lower in the hierarchy then them.
Fortunately, the caste system has been forbid by law, so nowadays all the people are able to communicate with each other, progress in life, have opportunities, and not be discriminated against.
