The correct answer is letter B
Explanation: This technique is very common and consists of selecting a population sample that is accessible. That is, the individuals employed in this research are selected because they are readily available, not because they were selected using a statistical criterion.
Answer: NSDAP was established in 1920. It was an expression of the disillusionment of one part of Germans after the First World War. It was that part that did not agree with Weimar regime. C is correct.
Explanation: NSDAP = national socialist party or nazi party. It was not founded by Hitler. At the very beginning socialism prevailed over nationalism. Hitler´s arrival to this party had a great effect: 1) he took advantage of above mentioned disillusionment in the German society, 2) he took advantage of ubiquity of anti-semitism. These two factors contributed significantly to his victory (1933 Hitler got legally to power - chanceller).
Answer: It produces inefficient economic results under certain conditions
Explanation: The above situation is known as the paradox of voting,which tries to show that the cost of voting will always be higher than the result obtained from the voting process.This is because Majority voting undermines the importance of an individual voter. This issue was first highlighted in 1793 by Nicolas de Condorcet,where noted that in a single stage election the influence of a single voter reduces as the number of voters increase.
The paradox of voting further highlights that the expected results/outcome of a voter from an electioneering process is less than what the initial expectations.
The Space Race was a period when the United States and Soviet Union
competed for technological advancements and scientific accomplishments.
This competition was a result of the Cold War that started after World
War II.
Exploring space during this era (late 1950's through the
beginning of the 1970's) was an unprecedented adventure for its time.
The world was shocked when the Soviet Union were able to launch Sputnik (
a satellite) into space. After this momentous accomplishment, the US
followed sending their own satellite into space several months later.
Both
of these countries took a significant risk, as their satellites,
spaceships, and other equipment could completely blow up. This would
result in the deaths of citizens. Along with this, they had to risk the
financial risk that this race caused. Each country poured in hundreds of
millions of dollars into their space programs over the course of 2
decades. If countries failed to achieve any breakthroughs, then this
money would have been wasted.
Despite the risks, this space race
had several positive effects on the world. This includes the
implementation of satellites that allow us to use GPS, the invention of
memory foam mattresses, and increased funding for public education.
