Im a freshmen this is a life question:(

Answers

Answer:

Yes, you will be put in the right grade as long as you failed bc of the coronavirus not because you usually take online classes.

Explanation:

Answer:

I mean, if you fail online school for the entire year I would assume they would have to make you repeat the year. However, if it was only for a semester or quarter they would most likely put you in some kind of summer school or remediation classes.

You should probably get in contact with the counselor from the school you're going to and ask them this question because it depends... I hope it all goes well.

Document 5:
Source: Testimony of Captain Diogo de Carvalho in the Inquisition trial of Luzia Pinta, a free Black woman from Angola, resident in Rio de Janeiro, Brazil, 1741.

I saw Luzia at the home of João Peixoto. There was a small altar with a canopy, and she had a curved knife in her hand, and was wearing a large ribbon tied on her head with the ends thrown backward in the style of an angel. And singing there with her were two other Black women, also from Angola, and an African man playing a small tambourine. And after two hours of playing and singing, Luzia became as if out of her mind, speaking things that no one understood. Many people who had come there to be cured were lying down on the floor, and she stepped over them various times. On these occasions it was said that she had the winds of divination, and she said that God told her on these occasions what she was to do. She also cured the wife of João do Valle. I also heard that many times she had been called to go to other towns to cure people.

Answers

I think the document is explaining who Luzia is and what she did. People (including herself) believed that God was working through her and gave her the power to cure people throughout Rio de Janeiro. The document was the captain's testimony as to what he saw her do and what he heard of her in her Inquisition trial.

As per the document that is taken from the testimonies of captain de Diogo de Carvalho in which the inquisition trials of the Luzia pinta as free black women from Angola is portrayed.

As per the text the luzia sees the house of João Peixoto. There she sees a small altar of canopy which had a knife in her hand and a ribbon tied to head some sort of dress. With her were some black women who were also from Angola. There was an African man who was playing a tambourine. After some moments of time the people who were invited were lying on the floor as luzia seemed to be enchanting some words.

They believed that god told her to do so as it represented a tridiagonal method of curing or healing people.

Answers

Answer:

One reason that people may desire to migrate away from metropolitan areas is an overcrowding population.

Explanation:

While living in a metropolitan area has many benefits (career and education opportunities for example) most people end up leaving because the busy atmosphere isn't for them. Whether there is a lack of sanitation from overcrowding, noise at all hours of the night, or the size of the population isn't desirable.
