Why did the Tea Act of 1773 anger many American colonists?
The law made tea difficult to buy.
The law restricted them from buying tea.
The law ended the tea trade in the colonies.
The law forced them to buy taxed tea.

Answers

Answer:

d

Explanation:

The tea act of 1773 angered many American colonists because the law forced them to buy taxed tea. The correct option is d.

What is the tea act of 1773?

The tea act of 1773 was an Act of the Parliament of Great Britain. The principal objective was to reduce the massive amount of tea held by the financially troubled British East India Company in its London warehouses and to help the struggling company survive.

A related objective was to undercut the price of illegal tea, smuggled into Britain's North American colonies. This was supposed to convince the colonists to purchase Company tea on which the Townshend duties were paid, thus implicitly agreeing to accept Parliament's right of taxation. Smuggled tea was a large issue for Britain and the East India Company since approximately 86% of all the tea in America at the time was smuggled into Dutch tea.

The Act granted the Company the right to directly ship its tea to North America and the right to the duty-free export of tea from Britain, although the tax imposed by the Townshend Acts and collected in the colonies remained in force.

What did you learn about diversity at the global, country, and institutional levels? Based on your understanding of diversity, what are some identities that are not represented? Why might it be important to be aware of those unrepresented identities? In the context of inclusion, how is a melting pot different than a tossed salad? How does understanding the difference promote diversity and inclusion?

Answers

The correct answer to this open question is the following.

You did not include any reference of context, so we are going to answer in general terms.

What I learned about diversity at the global, country, and institutional levels is that people are different, and differences do not make some good or bad, or better or worst. We have to learn to respect differences because in diversity we recognize more and better things. Diversity is good for society.

Some identities that are not represented oftentimes are ethnicities and sexual oriented diversity, and I consider it important to be aware of those unrepresented identities because they are part of society with people that proudly live their belief systems.

Regarding inclusion, a melting pot is different than a tossed salad by the way people can be integrated without differences of race, gender, sexual orientation, nationality, or culture. The idea of true inclusion is to have all kinds of personalities, styles, and backgrounds, integrated and acting in the same social environment without finger-pointing, segregation, or judgment.

If people really understand the difference, diversity could be promoted in all levels of society, and inclusion would not ever be a distant concept that could be "utopic," but a real possibility that could be the new way people behave and conduct their lives.

Diversity at the global, national and institutional levels can be variable in the sense that there are different cultures, habits and behaviors across the world, and each has its own set of rules and values.

We increasingly live in a multicultural environment, where different cultures interact in the same environment, which is a positive point for the development of society and increasing social and organizational knowledge.

There are still cultural identities in society that are not represented, that is, they are based on negative stereotypes and make these individuals afraid to demonstrate their identity and suffer prejudice and discrimination.

In the context of inclusion, a melting pot is different from a tossed salad, in terms of homogeneity that should not be promoted, but cultural diversity, where each identity is respected.

Therefore, understanding the difference between individuals promotes inclusion, as each person must be respected through their culture and treated with dignity and ethics.
