A landowner owned a large tract of land in an area zoned for medium residential use. Permitted uses in this zone are single-family dwellings, condominium and townhouse developments, and moderate density apartment complexes. The landowner subdivided her land into 10 lots and conveyed each lot by a deed restricting the land to single-family use. All deeds were duly recorded and all lots were developed as single-family homes.

The owner of lot 1 died and his property passed by will to his niece. Some time later, the owner of lot 3 sold his property to a buyer by a deed that did not contain the covenant limiting use to single-family dwellings. The buyer subsequently sold lot 3 to her friend, and did not include the covenant in the deed. Both deeds were duly recorded. A storm destroyed the friend's home, and in its place he began to build a three-unit townhouse.

May the niece sue to enforce the covenant against the friend to prevent him from building the townhouse on lot 3?
A. No, because there is no privity with the friend.
B. No, because the zoning laws have not been violated.
C. No, because there was no restriction in the friend's deed.
D. Yes, because the friend's townhouse would alter the landowner's common scheme.

In this unit, you learned about civilizations that once existed in Europe and the Middle East. You also learned about different types of governments that were created by these civilizations. Identify the different types of governments that you learned about and the related civilizations. Compare and contrast these governments using facts from the lessons. Next, imagine you are a leader of a new civilization in this region. Which type of government would you support in your kingdom or empire? Why?

Answers

Answer:

There were 2 primary types of government, a democracy, and a hierarchy. A hierarchy had a few different variants, the ruler had all power and was a god, the ruler controlled people, and the ruler had the most power but had a small house of other "government officials"

If I had a kingdom, it would have a democracy as its government. A group of advisors, the house/senate, and what many think is the ultimate power but has equal power, the president/king. Democracy is important. Not too much though, or else you get communism. Now, things were different back then. Most people kept what they had, and the citizens ran their own "government" of sorts. But a democratic government is still needed to control, and maintain the people. When I say control, I don't mean "give me all of your money and earnings and we will give you what you earned in food, water, clothes, and a house." That's communism. What I mean by control, is enforce the rules, make sure that the people don't tear each other apart, limb from limb. The people need guided to the decided way of living, which THEY CHOSE by voting. Therefore, they chose to follow these guidelines, and should not argue. That is how to run a stable government. On paper. Of course, there would be plenty of people who want to cause problems, but those things are too unpredictable to handle without communism. Not saying that it is the only way to run a government, what I meant was those things will be deal with at the time and can't be fixed on a simple word document for a history lesson on a computer learning system meant for a sixth grader to answer in a few sentences, about why you should be good to people, and not meant to go into detail about communism, and meant to see who understands how to live a happy human life, and who knows how to be the next "president" of Russia, and also just to see students creativity and knowledge of world politics as well as their downright opinion. I probably went into a lot of detail but hit the word limit.

how can we utilise our fundamental rights​

Answers

Answer:

Fundamental rights in India are the rights guaranteed under Part III (Articles 12-35) of the Constitution of India. There are six fundamental rights (Article 14 - 32) recognised by the Indian constitution : the right to equality (Articles 14-18), the right to freedom (Articles 19-22), the right against exploitation (Articles 23-24), the right to freedom of religion (Articles 25-28), cultural and educational rights (Articles 29-30) and the right to constitutional remedies (Article 32 and 226).[1]

While the Constitution also creates other rights, such as the Right to Property, they are not fundamental rights. In cases of fundamental rights violations, the Supreme Court of India can be directly petitioned under Article 32 of the Constitution. The Rights have their origins in many sources, including England's Bill of Rights, the United States Bill of Rights and France's Declaration of the Rights of Man.

Fundamental rights for Indians have also been aimed at overturning the inequalities of pre-independence social practices. Specifically, they have also been used to abolish untouchability and thus prohibit discrimination on the grounds of religion, race, caste, gender or place of birth. They also forbid trafficking of human beings and forced labour (a crime). They also protect cultural and educational rights of religious establishments. Right to property was changed from fundamental right to legal right.

The number of repressive governments has decreased drastically C. Companies are investing in countries that have favorable labor laws D. The WTO has succeeded in eliminating many immigration laws

Answers

Answer:

A. Workers are going to developed countries in search of better-paying jobs

Explanation:

The term "labour mitigation" refers to the decrease in job offers that happened on a large scale during certain periods of globalization. This happened because with globalization, many workers were free to move from country to country and try to get better wages and better working conditions in more industrialized countries. This reduced the offer of employment in these countries, as there was a large number of vacancies being filled by foreign workers.

In order to finance the purchase of a property, the buyer received a loan and in return gave the lender a promissory note secured by a mortgage on the property. Subsequently, the buyer divided the property into two parcels, retaining one of the parcels and selling the other to a friend. The friend took the parcel subject to the mortgage. The buyer and the friend agreed that each would be liable for one-half of the outstanding mortgage. One year later the buyer disappeared. Since the buyer was no longer paying one-half of the mortgage obligation, the lender threatened to foreclose on the property. The friend paid off the outstanding balance of the loan. The applicable jurisdiction recognizes the lien theory of mortgages. Can the friend bring a foreclosure action against the buyer's parcel?

A. Yes, because the friend is subrogated to the lender's rights in the parcel.
B. Yes, because the friend obtained ownership rights in his own parcel by purchase.
C. No, because the friend does not have an ownership interest in the parcel since the jurisdiction adheres to the lien theory of mortgages.
D. No, because the friend was not under a legal duty to pay the buyer's portion of the mortgage.
