Excerpt from Stuff Matters
By Mark Miodownik

At some point humans made the discovery that would end the Stone Age and open the door to a seemingly unlimited supply of the stuff. They discovered that a certain greenish rock, when put into a very hot fire and surrounded by red-hot embers, turns into a shiny piece of metal. This greenish rock was malachite, and the metal was, of course, copper. It must have been the most dazzling revelation. Suddenly the discoverers were surrounded not by dead inert rock but by mysterious stuff that had an inner life. They would have been capable of performing this transformation with only a few particular types of rock, such as malachite, because getting it to work reliably depends not just on identifying these rocks but also on carefully controlling the chemical conditions of the fire. But they must have suspected that those rocks that didn’t work, that remained obstinately rock-like however hot the fire became, had hidden secrets. They were right. It’s a process that works for many minerals, although it would be thousands of years before an understanding of the chemistry required (controlling the chemical reactions between the rock and the gases created in the fire) led to the next real breakthrough in smelting. In the meantime, from around 5000 BC, early metal smiths used trial and error to hone the process of the production of copper. The making of copper tools initiated a spectacular growth in human technology, being instrumental in the birth of other technologies, cities, and the first great civilizations. The pyramids of Egypt are an example of what became possible once there were plentiful copper tools. Each block of stone in each pyramid was extracted from amine and individually hand-carved using copper chisels. It is estimated that ten thousand tons of copper ore were mined throughout ancient Egypt to create the three hundred thousand chisels needed. It was an enormous achievement, without which the pyramids could not have been built, however many slaves were used, since it is not practical to carve rock without metal tools. It is all the more impressive given that copper is not the ideal material for cutting rock since it is not very hard. Sculpting a piece of limestone with a copper chisel quickly blunts the chisel. It is estimated that the copper chisels would have needed to be sharpened every few hammer blows in order for them to be useful.
What is the author’s main message? A) Copper was the first metal used by humans.
B) Copper was a critical tool in building the pyramids.
C) Humans were not able to effectively use copper at first.
D) The discovery of copper was the beginning of civilizations.

I run four miles every morning. Which word or words make up the complete subject in this sentence?

Answers

Answer: I

Explanation: To find the subject of a sentence you need to find the noun being talked about. The noun would not be "four miles" or "every morning" because there is no verb talking about them. "I" on the other hand, is being talked about. The verb "run" is describing what "I" did.

Read the excerpt from "Healthy Eating."

It may be an old adage, but it's a goody: you are what you eat. It's also when you eat and how much you eat. And while we can all sympathize with the need to have things fast and easy in our busy lives, nutritionists say eating well is actually not that hard. It just takes planning and, some would say, a little help from the village.

What makes this part of author's argument effective?

She uses a quotation from an expert.
She uses facts from a reliable source.
She addresses a counterclaim.
She supports her claim with reasons.

Answers

Answer:

She probably used facts from a reliable source.

B. She uses facts from a reliable source.

The author in the excerpt references facts from trustworthy sources to make it more powerful. Option B is therefore right.

The key to a healthy diet is to consume the right amount of calories for your level of activity, balancing the energy you take with the energy you expend. If you eat or drink more than your body requires, you will gain weight because the energy you do not use is stored as fat.

What are the advantages of eating healthily?

A balanced and nutritious diet is essential for good health. It protects against chronic non-communicable diseases such as heart disease, diabetes, and cancer.

A healthy diet calls for a variety of foods as well as a reduction in sodium, carbs, saturated fat, and industrially generated trans-fats.

Read the passage about the life of Jackie Robinson.

During Jackie Robinson’s time, Major League Baseball was still segregated. Jackie was drafted by Branch Rickey to change all of that and integrate baseball. Branch knew Jackie would face some tough times, and Branch made him promise not to fight back when he faced this racism, which often came from his own teammates. Jackie and his family even received terrible threats from those in the crowd. Despite all of this, on April 15, 1947, Jackie became the first African-American athlete to play in the major leagues. In his decade-long career with the Dodgers, Jackie helped his team win the National League pennant several times. In 1955, he helped them achieve the greatest victory of all: the World Series.

This man came back into my office, but his tone was changing, and I could see that he no longer regarded me as an innocent. Obviously, he had figured out that I was also part of what had been secret. He came in and stood over me, saying, in a harsh voice, "Now it's your turn." He reached down and took the keys that Koophuis had given me.

I stood up, coming face to face with this man. I could feel his hot breath, we were standing so close. I looked him right in the eye and said in German, "You are Viennese. I am from Vienna too."

Do you think every school has equal opportunities and one's
Success simply depends on how much they put into it? Or do
you think some schools offer more opportunities for success
than others?

Answers

Answer:

Every school is different and based on that, students are not given equal opportunities.

Explanation:

Public schools are funded differently. (I can discuss private schools later) Wealthier cities will be able to spend more on educations and provide their students with better materials. Naturally the students' families themselves are also wealthier, so they can afford more supplies/classes/extracurriculars that will better help them in the future. Poorer cities have less money in their budge to spend on education. Therefore, the technology may be lacking and the school will not be able to spend as much money on their students.

There should be articles on this. You can search simply for "are schools equal." If you are interested in debate, specifically LD, you can check out the standarize testing topic, which is very interesting and touches upon the idea of whether or not schools are equal and how a students' background has an impact on their scores.
