The correct answer is B. They were able to find the orbit of a comet and predict the year of its return.

Edmond Halley was a British astronomer, geophysicist, mathematician, meteorologist, and physicist. Alexis Clairaut was a French astronomer, geophysicist, mathematician.

They were friends with Isaac Newton that before, had built a new theory of universal gravitation.

With this new theory, Newton calculated the orbit of the Great Comet of 1680. Later, Halley used Newton’s theory to calculate the orbits of several comets - even some that were in ancient records -. The thing is: Halley noticed that some comets had similar orbits, which led him to suggest that some comets may be periodic and that they may be moving along very elongated ellipses. This way he forecasted the comets return in a period of 76 years.

Since then, the comet has carried Halley’s name.

<h3>Answer:</h3>

D. Because the Sudanese government focused on rebels in general,

not a specific ethnic group.

<h3>Explanation:</h3>

Since the early 2000s, violence against the Sudanese government has been prevalent in the Darfur region. Although, it was not defined as genocide by the UN.

Genocide

First, we need to understand what genocide is.

  • Genocide is defined as the deliberate killing of a specific ethnicity, nationality, or religious group.

For the UN to declare something a genocide, a specific group, usually a minority, must be targeted for their unique traits, like ethnicity.

There are 5 forms of genocide:

  1. Killing members of a group
  2. Causing grave mental or physical harm
  3. Forcing purposely terrible living conditions
  4. Preventing new births
  5. Forcing children out of the group

One of these must occur to a specific group of people for the UN to declare genocide.

Atrocities in Darfur

While the Sudanese government did deliberately kill people within Darfur, the government attempted to attack rebels. So, the government did not specifically target the ethnicity. However, the majority of the rebels were from Darfur, so some people saw it as a genocide.

Philip II Augustus greatly increased the power of the French monarch by what?
dexar [7]
<h2>Answer:</h2>

Felipe II Augustus, greatly increased the power of the French monarchy by its important military victories and, above all, for the development of the projects carried out to ensure the royal power against the great feudal lords.

He was crowned king in his teens, although he was known to be austere and poorly educated intellectually, was considered a good ruler because he surrounded himself with scientists, trying to be fair to his subjects, and greatly expanding the territorial spread of France.

Finally, at the end of his reign France was geographically strengthened, which is why he was considered the great architect of the French union during his prolonged reign.

1. Railroad can now give supplies better but now many are homeless

2. Think of it simplistically, if an employer can pay 5 people with $10 each (just an example), and then now the employer is forced to give each person $12.50, that means he’s now forced to lay off one of those 5 people so the other 4 people can have $12.50 each.

Basically it results in employees making more money, but also that other employees suffer and lose their jobs because of it. People want to raise minimum wage until they lose their jobs lol
