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.

Answers

Answer:

Justice and fairness.

Explanation:

Franklin never truly received the perfection he had wanted for himself, as well as others. This goes to show that he needed to be more fair to others rather than wanting everyone to be perfect, whenever he couldn't even get this nor achieve it for himself. This also shows Justice due to him getting the embarrassment he deserved, but atleast he was the one to admit his failure.

But the road has been neglected for a long time. The surface of the road is broken by the heavy rains. There are heaps of road metal on both sides of the road. They leave only little room in the middle. The side rains are blocked and the water flows out slowly. So the road get flooded even after a slight rain. There are potholes on the road. The broken culvert is also a danger for vehicles specially at night. This road serves a large number of houses in this area. There is a lot of traffic along the road at any time of the day. So we are grateful to you if you taken action to repair the road.

excerpt from “Solitude” by Henry David Thoreau This is a delicious evening, when the whole body is one sense, and imbibes delight through every pore. I go and come with a strange liberty in Nature, a part of herself. As I walk along the stony shore of the pond in my shirt sleeves, though it is cool as well as cloudy and windy, and I see nothing special to attract me, all the elements are unusually congenial to me. The bullfrogs trump to usher in the night, and the note of the whippoorwill is borne on the rippling wind from over the water. Sympathy with the fluttering alder and poplar leaves almost takes away my breath; yet, like the lake, my serenity is rippled but not ruffled. These small waves raised by the evening wind are as remote from storm as the smooth reflecting surface. Though it is now dark, the wind still blows and roars in the wood, the waves still dash, and some creatures lull the rest with their notes. The repose is never complete. The wildest animals do not repose, but seek their prey now; the fox, and skunk, and rabbit, now roam the fields and woods without fear. They are Nature’s watchmen, —links which connect the days of animated life. . . . Some of my pleasantest hours were during the long rain storms in the spring or fall, which confined me to the house for the afternoon as well as the forenoon, soothed by their ceaseless roar and pelting; when an early twilight ushered in a long evening in which many thoughts had time to take root and unfold themselves. . . . Men frequently say to me, “I should think you would feel lonesome down there, and want to be nearer to folks, rainy and snowy days and nights especially.” I am tempted to reply to such,—This whole earth which we inhabit is but a point in space. How far apart, think you, dwell the two most distant inhabitants of yonder star, the breadth of whose disk cannot be appreciated by our instruments? Why should I feel lonely? Is not our planet in the Milky Way? This which you put seems to me not to be the most important question. What sort of space is that which separates a man from his fellows and makes him solitary? I have found that no exertion of the legs can bring two minds much nearer to one another. Read this excerpt from “Solitude” by Henry David Thoreau. The wildest animals do not repose, but seek their prey now; the fox, and skunk, and rabbit, now roam the fields and woods without fear. They are Nature’s watchmen —links which connect the days of animated life. How does Thoreau distinguish the natural world, perhaps in contrast to the human world? He describes the organized structure of the forest world. He describes the manner by which the forest sustains life. He characterizes nature by its lack of reservation. He characterizes nature by its constant alertness and activity.

Answers

Answer:

He characterizes nature by its constant alertness and activity.

Explanation:

Thoreau`s description of nature is characterized by contrast. He is calm, enjoys a walk by the lake, nothing upsets him, but the vice versa, he is breathing with the nature around him and follows its steps. On the other hand, nature, as always is alive, wind, clouds, waves, animals, everything is moving, living untouched by random visitors like Thoreau. So from the lively surroundings and eternally active spirit of nature, he extracts the feeling of peace.

Amira is punctilious about where everything in her room should go, and can't stand it when anything is out of place. Her friend Luz is the exact opposite, leaving a trail of stray pens, sticky notes, and unmatched gym socks wherever she goes. What does the word punctilious most likely suggest? Select two options. that Amira is somewhat neat that Amira is indifferent about how her room looks that Amira is controlling with regard to details that Amira is lazy and unmotivated that Amira is uptight about cleanliness

Answers

Answer:

The two options which express what punctilious most likely suggests are:

C. that Amira is controlling with regard to details

E.  that Amira is uptight about cleanliness

Explanation:

Even without having ever seen the word "punctilious" before, we can guess its meaning based on context clues. First, we are told that Amira is punctilious when it comes to her room and the objects in it. She is then compared to her friend, Luz, who happens to be completely different than her. Luz does not care about cleanliness or organization. Now that we know that trait about Luz, we can easily assume what "punctilious" means about Amira. If they are complete opposites, that means Amira is super organized and neat. She cares about where each thing goes. With that in mind, we can easily choose the two correct options:

C. that Amira is controlling with regard to details

E.  that Amira is uptight about cleanliness

He is very studious and a bit of a perfectionist, and he’s always anxious to learn new things. It’s hard to believe that anyone can be that focused. But me? Well, that’s a different story. I am much more likely to spend my time daydreaming.

Which words from the passage are a good example of direct characterization?

I lazily flipped through the pages of my textbook
Too bad I can’t be more like my brother

Answers

ANSWER: The answer is C

The option from the passage that is a good example of characterization is;

C. He is very studious and a bit of a perfectionist

Characterization is the act of describing the personalities of the characters in a work of fiction. This can be either done directly or indirectly.

The above option represents a direct characterization. This is because the narrator explicitly mentioned the attributes of the individual being described. There is no room for guessing.

This is unlike the indirect characterization where the readers are expected to guess the personalities of characters through clues that are provided.

Summarily, the option that is a good example of characterization is C. He is very studious and a bit of a perfectionist.
