did you know that Ancient metalworkers in East Africa knew the secrets of strengthening their iron. They knew that if they melte

d their iron in a furnace fired with coal, then when it cooled and solidified it would be harder than the original iron. What really happened inside the hot furnace? Coal is a form of carbon, so when its heat melted the iron, tiny particles of carbon dissolved into the liquid iron. This formed a solution. When the mixture of carbon and iron cooled and solidified, it was much harder than the original iron. Since it was harder, it was much more useful for building things like tools and weapons. This solution of carbon dissolved in iron is called steel. Every time you use a tool made out of steel, you are benefiting from the discoveries of those ancient metalworkers from long ago.

Which sentence might be used to depict the voice of a young character?
LenaWriter [7]

The answer to your question would be that the sentence that can be used to depict the voice of a young character is the following one: We ran the cars and jumped in because we hated school.

I believe that this is the correct answer because of the word choices selected by the speaker. The verbs used are simple verbs of momevent (ran) or phrasal verbs (jumped in). Consequently, the tone is very informal, as opposed to the other sentences which make use of formal word choices adding a lot of description to the passage (eager to jump in our parents' cars, empty parking lot, bursting with excitement, dreaded school, glad to finally be leaving school).

what are different types of schools one can consider, when looking into schools that may have programs that match their interest
Leokris [45]

Each School type has it's own unique benefits and challenges;


If you are interested in college schools you can consider these categories:

  • Dream schools: which are colleges where your academic credentials fall in the lower end or below.
  • Target schools: where your academic credentials fall within the school's average range for the recently class that is accepted.
  • Safety schools: where your academic credentials exceed the range for any average first-year student.

Or if you're about Secondary, High School or so, they can be classified in 2 major types:

  • Public Schools: which are universal (available to everyone) and they are funded and controlled by the government.
  • Private Schools: which are not funded or operated by federal, state or local governments.

Among Public Schools we can include:

Magnet schools, Charter Schools, Urban Schools, Rural Schools

and High Needs Schools.

And among Private Schools we can include  

Military schools and Boarding schools.
