What are the problems scientists are trying to solve in order to get to Mars?

Answers

Answer 1
Accessing water is the biggest problem I would say, it is obviously one of the things humans can’t live without and Mars lacks of water. Another problem would be the colder weather and the carbon dioxide atmosphere.
Scientist are also trying to find a safer way to get the astronauts to Mars, because taking a trip there causes them to be exposed to radiation.

Which group followed the advice given in this address?

Isolationists regarding the Treaty of Versailles after World War I


Hawks in Congress during the Vietnam War


Civil libertarians in Congress after the start of the War on Terror


Expansionists during the Spanish-American War

Answers

The correct answer is Isolationists regarding the Treaty of Versailles after World War I

Explanation:

George Washington's words proposed the idea nations should not be part of political issues between other nations. This is expressed in "to have with them as little political connection as possible". This idea is related to the policy of isolationism that refers to nations avoiding participation in international issues.

Moreover, this policy was supported by isolationists in the U.S. regarding the Treaty of Versailles because this treaty proposed the creation of an organization known as the League of nations and as part of this, countries participating including the U.S. accepted to enter the war if necessary, which implied intervening in the conflicts of other countries and this was opposite to the policy of isolationism.

Scopes changed his plea to guilty, and was convicted.
Scopes lost and appealed to the US Supreme Court.

Answers

The correct answer would be the 3rd option:

Scopes changed his plea to guilty, and was convicted.

Hope this helped!

Scopes changed his plea to guilty and was convicted which best states how the Scopes trial ended. The correct option is C.

Why did John Scopes oppose the Butler Act?

Scopes was accused of violating Tennessee's Butler Act, which made teaching human evolution in any state-funded school illegal. The trial was staged on purpose to draw attention to the small town of Dayton, Tennessee, where it was held.

The Butler Act, passed by the Tennessee legislature in March 1925, made it illegal to teach any doctrine that denied the divine creation of man as taught in the Bible.

Scopes was found guilty and fined $100, but on appeal, the Supreme Court of Tennessee overturned Scopes' conviction while finding the Butler Act constitutional, citing a technicality in the issuance of the fine.

Thus, the ideal selection is option C.
