2. What does George Will mean when he says independent candidates could “splinter the electorate”?
Why would this be important?

Answers

Answer:

Explanation:

When George Will says independent candidates could “splinter the electorate”, he means that amalgamation of broad concensus with independent parties through coalition and agreement would eradicate the winner-take-all electoral system.

George Will thinks this is important because winner-take-all electoral votes make the winner look like he/she has won by a large majority or represents national decisiveness even when he/she wins only by a close margin of votes.

In other words, the whole electoral votes of a particular state go in the hands of the winning candidate and the defeated candidate along with the rest of the people who supported the defeated candidate lose all thier electoral votes.

The thing which George Will meant when he said independent candidates could “splinter the electorate” is:

They could split the votes with Democrats and Republicans losing important votes

According to the given question, we are asked to show what  George Will meant when he said independent candidates could “splinter the electorate”.

As a result of this, we can see that there are an Independent candidate was yet to win a United States presidential election after George Bush had and it was generally accepted that they could not swing enough votes to win.

With this in mind, George Will believed that independent candidates were sure they would not win, but would splinter the electorates with important votes which could have helped either the Democratic or Republican candidate would be lost.

How did Newton describe the concept of gravity and how did it add to the building knowledge of the movements of the heavens?

Answers

Answer:

The legend is that Newton discovered gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest. Gravity is what helps keep objects upright in space, so without gravity we'd all be floating around right now.

Write a paragraph 5-6 sentences on the rise of city states in Greece.

Answers

Answer:

City states in Greece rose from the start of Ancient Greek City, the first of them being Knossos, in Crete. The reason for this is that Greek geography is very difficult to manage: having several mountain ranges, steep cliffs, and peninsulas that made it difficult for a single political entity to rule over all of the land. For this reason, smaller political entities like city states became the preferred method of organization.

after nine states had ratified the constitution by mid-1788,

1. other states quickly followed
2. all thirteen states had to obey it
3. it became law in the United states
4. none of the states had to obey it ​

Answers

Answer:

Explanation:

C, I got the answer from quizzes, if not C than A.

Once nine states had ratified the constitution by mid-1788, it reached the required threshold for it to become law in the United States, establishing the Constitution as the governing framework for the entire nation. Therefore, option 1 is correct.

Ratified refers to the formal approval or acceptance of a document or agreement through an official process. In the context of the Constitution, ratification involved the act of giving consent and endorsement to the proposed framework of government by the states.

Each state had its own ratification process, usually involving a vote by state legislatures or specially convened ratifying conventions.

Once a sufficient number of states, specifically nine out of the thirteen, had ratified the Constitution, it reached the required level of acceptance, enabling it to become the law of the land and establish a unified system of government for the United States.

Should the Electoral College continue to be used? Why or why not? Use examples from your research to support your answer.

Answers

Answer:

No

Explanation:

It permits the election of a candidate who does not win the most votes; and. Its winner-takes-all approach cancels the votes of the losing candidates in each state.

Answer:

No, the United States should not continue to use the Electoral College. It is undemocratic. First, it takes a winner-take-all approach, and it cancels the votes of that were cast for the losing candidates in each state.  Another problem with the Electoral College is that five times in our nation’s history, it has permitted the election of a candidate who has not won the popular vote.  Two examples are during the 2000 election, Al Gore won the popular vote, however George W. Bush was elected and during the 2016 election, Hillary Clinton won the popular vote, but Donald Trump was elected.

Explanation:

This is an opinion.  However some facts to help with the opinion include that the Electoral College was created out of a compromise during the Constitutional Convention.  It was created to prevent corruption between the members of executive and legislative branches of government. The Electoral College is also used to be a "check" on the regular citizens, because at the time of the Constitutional Convention, the Founding Father's did not necessarily have complete faith in the masses. The United States has changed since the Constitutional Convention and so has the makeup of voters. The right to vote during the Colonial and Revolutionary periods was restricted to white, Protestant, male property owners over the age of 21. Since then, there have been Constitutional Amendments that have allowed more people to vote including women, African Americans, and all members of other minorites who are citizens over the age of 18. Today our voting population is more informed also.

How did Chandragupta Maurya achieve control over such a large empire? By centralizing the government and breaking the area into regions and then provinces By attacking all areas and instilling fear in the people By settling near rivers in order to have abundance of resources By bribing other kingdoms to enforce and follow his laws

Answers

The correct answer is A) By centralizing the government and breaking the area into regions and then provinces.

Chandragupta Maurya achieved control over such a large empire by centralizing the government and breaking the area into regions and then provinces.

What he does was take full control of the government by centralizing the main administrative activities of the empire so he could oversee the most important aspects of the government. He divided the territory into provinces to better handle the administration of each one. He also allowed the creation of a group of counselors or ministers that formed a council to support the administration.
