Why was switching from chains to cables in the building of roller coasters important?

Answers

Answer 1
Answer: Switching from chains to cables in the building of roller coasters was important because cables are less likely to snap when hauling several tons of roller coaster cars full of people. Chains are made of linked, welded pieces of metal that can easily snap if they pull too much. Cables, while they can snap, are much less likely to do so, because they're a stretch of fibers, be it metal or other, without any potential weak spots.

Can someone proof read this:How are the characters affected by the Nazi regime thus far?The time and place has a huge impact on the characters and their everyday life. For starters, Liesel lost her entire biological family due to the rule of Nazis. Her communist father was taken away by the government, and trying to do the best for her daughter and son, her mother leaves her home and takes a journey to Munich to give her children to a foster family. Due to the lack of strength in Werner’s, Liesel’s brother, immune system, he dies on the train on the way there. Her brother was then buried and that’s where Liesel stole her first book. Liesel and her mother then travel to Munich and meet Hans and Rosa, and Leisel starts living with them. Thus far, we see changes in Liesel’s life. The obvious are all negative, such as her entire family collapses and Liesel has to change her entire life, but there are positives too. For example, due to her brother dying and the funeral commencing, and her stealing a book, Liesel found her passion for books, and met Hans, who changed her life incredibly. But Leisel was not the the only one affected. Hans used to paint houses, and most of his customers were Jewish, meaning Jews provided him his main income source. But when the diastrous events of the Holocaust and WW2 happened, Hans and Rosa had to find other ways to make it by. And speaking of Rosa, her job of delivering the laundry steadily declined in customers as WW2 had many people strained to make ends meet.

Is this thesis statement grammatically correct? Does it flow well? Correct it if not please. Despite the slum being constantly saturated with violence, the most meaningful theme in “La Limonada” is hope, because it continued to motivate Jonathan Orozco during painful and dark times and the love from his mother sustained his hope.

Answers

Everything is correct in the thesis statement with well written topics. You did a really good job on also making it informational. This also helps you do well in the writing process for your assignment. Good Job! :)

Miguel is a hardworking boy around the age of seventeen. He is originally from Mexico and has been living in the United States for four years. He is able to understand English, however always writes in Spanish. He has seen an American flag, but couldn’t tell you much about it. He also can sing the national anthem, but doesn't understand the lyrics. Can Miguel become an American citizen if he applies for citizenship tomorrow? Devise a plan to help Miguel earn his citizenship in the United States.

Answers

Answer:

Miguel can't become a citizen yet. There are a number of reasons for this:

1) he's not 18 yet; he has to wait until he is 18

2) he hasn't lived in the US for 5 years (but if he waits till he's 18, will will have, so both these conditions get fullfilled at the same time)

3) he must speak English: pass an English test.

I would recommend that Miguel spends the next year practicing his English speaking and writing, this is the most important!

4) he must understand US history and government structure: this is another thing that he must do.

this means he cant become a citizen

Explanation:

NO,
 
In order to be a U.S citizen, you would have to be at least 18 years old and be a permanent resident for at least 5 years.
