When Pete Seeger appeared before the House Un-American Activities
Committee in 1955, he refused to answer the committee's questions about
his personal beliefs. He based his refusal on:
A. the Fifth Amendment, which says you can't be forced to testify
against yourself.
B. the Sixth Amendment, which guarantees a speedy trial by an
impartial jury.
C. the First Amendment, which guarantees freedom of speech.
D. the Fourth Amendment, which guards against unreasonable
search and seizure.

Answers

Answer:

The First Ammendment, which guarantees a person the right to free speech.

Explanation:

The reason he based his refusal on the First ammendment is because he wanted them to know that he was entitled not to answer their questions. That meant that he could also say nothing because it was his will not to speak at all.

When Pete Seeger appeared before the House Un-American Activities Committee in 1955, he refused to answer the committee's questions about his personal beliefs. He based his refusal on the First Amendment, which guarantees freedom of speech. Thus the correct option is C.

What is the First Amendment?

The First Amendment protects an individual's freedom to express himself or herself in any perspective, whether it be a general or political viewpoint based on his or her own personal views, observation, and understanding.

The English Bill of Rights constrained governmental power and gave citizens more freedoms, enabling them to express themselves freely and engage in free speech.

In the given case, He refused to answer their inquiries because he wanted them to understand that he had the right not to because of the First Amendment. That implied that he could remain silent as well because it was against his will to do so.

Therefore, option C is appropriate.

Can you think of a historically significant reason why cinema is helpful to us today when looking back at the turn of the 20th century?

Answers

Answer:

Explanation:

Cinema is one of the important historical documents. When we watch films from the turn of the 20th century we can see a lot about the society of that era. In the movies, it is clear what were the important topics of the society at that time, what were the beauty standards, what their views of the world were, etc.

Additionally, the cinematic industry can tell us more about politics as cinema was often used as a means of propaganda since its invention. Various mainstream movies were made to convey the specific messages, and by watching certain movies we can see what were the political thoughts of the time. Hollywood cinema, for example, was in service of American politics, and if we watch a movie made at the turn of the century in Hollywood, we could analyze it and see what were political questions at the time and what was the mainstream thought of the society.

Creating Lake-Effect Snow

Situated on Lake Erie, the city of Buffalo, New York, is one of the snowiest cities in the United States. Like other cities on large lakes, it is subject to a phenomenon called lake-effect snow. Water retains heat, so lake water is often warmer than the air. In the lake effect, cold air moves over warmer lake water, initiating a process that can produce large snowstorms. Moisture from the lake evaporates into the cold air, warming it. Because warm air is less dense than cold air, it begins to rise. As it rises and moves away from the lake, it cools down. As the air cools, moisture condenses and forms into clouds. If the temperature is cold enough, the moisture falls to the ground as snow.

What is the main idea of the passage?

A, When cold air moves over the warmer water of a lake, lake effect snow can be produced.

B, In the lake effect, warm air, which is lighter than cold air, rises and moves away.

C, Buffalo, New York, gets more snow than most cities in the United States.

Explanation:

Writing editorials would be the editor's and journalist's job. Creating graphics for advertisements could be a possible answer, but those would be created by either the advertiser themselves or a graphic designer that they hired. Maintaining a social media account is another possible option, but pretty limited seeing as we don't have enough information to know if the artist is the one creating the posts or is being given what to post by their employer.
