Question 1

Read the passage:
Gods and men alike suffered from the sorrow of Demeter. To her, in pity for the barren earth, Zeus sent an embassy, but in vain it came. Merciless was the great Earth Mother, who had been robbed of what she held most dear.

"Give me back my child!" she said. "Gladly I watch the sufferings of men, for no sorrow is as my sorrow. Give me back my child, and the earth shall grow fertile once more."

Why does the final line provoke Zeus to make a decision?

Question 1 options:

Zeus takes pity on Demeter because she seems so desperate for help getting her daughter back.


Zeus realizes that the kidnapping of Proserpine was wrong and he needs to punish Pluto.

Zeus realizes that granting Demeter's request to return her daughter to her will be good for the whole world.

Zeus knows that he is responsible for Demeter's daughter and decides to help her out of the goodness of his heart.

Question 2
Read the passage:

"Who are you?" he whispered, as he was melting at the young chieftain's feet.

"I am Go hay—the Spring," answered the young chieftain. "All the earth is glad, when I come to drive you back to your lodge in the North Sky, for I bring sunshine, and love, and joy."

Why does the last line of dialogue cause Old Man Winter to act?

Question 2 options:

Go hay's words strike fear into Old Man Winter, causing him to finally decide to leave.

Old Man Winter was touched by how beautiful the springtime was, so he left to make room for new life.

Go hay's words were so funny that Old Man Winter became friends with him.

Old Man Winter decided that it was too much trouble to argue with Go hay, so he left willingly.

Question 3
Read the passages:

Back to the flowery island of Sicily her mother brought her, and the peach trees and the almonds blossomed showily as she passed. The olives decked themselves with their soft grey leaves, the corn sprang up, green and lush and strong. The lemon and orange groves grew golden with luscious fruit, and all the land was carpeted with flowers. For six months of the year she stayed, and gods and men rejoiced at the bringing back of Proserpine. For six months she left her green and pleasant land for the dark kingdom of him whom she loved, and through those months the trees were bare, and the earth chill and brown, and under the earth the flowers hid themselves in fear and awaited the return of the fair daughter of Demeter.



"I, too, am powerful, and I am young! I do not fear you. When I touch the earth, it grows soft and warm. Every living thing stirs in its sleep,—birds and bees, flowers and trees, animals and men. When I speak, the sleeping sun awakes. See! Already he begins to send down his arrows. Hasten! that they may not find you, on the trail to the North Sky."

The Old Man trembled. His legs and arms grew weak. Icicles fell from his beard. Great tears rolled down his cheeks.



How do these two texts depict spring in similar ways?

Question 3 options:

Both use words that carry positive connotations in order to depict spring as a time of rebirth and growth.


Both use images to show that spring is a dark and quiet time of year.

Both use images that show that spring is inevitable and it is not more important than the winter or any other season.

Both use words that carry negative connotations in order to show that the passing of winter is a sad and unhappy time.

Question 4
Demeter and Old Man Winter both cause winter in their respective myths.

How are these two figures characterized differently in each text?

Question 4 options:

Demeter is characterized as a figure motivated by her own grief and sadness, while Old Man Winter is shown to be someone motivated by anger and a desire to cause mayhem.

Demeter is shown to not mind if she causes suffering, while Old Man Winter is characterized as a kindhearted person.

Old Man Winter is shown as someone who is mean and malicious, while Demeter is shown as someone who helps people out of kindness.

Old Man Winter is characterized as someone who is motivated by his shortcomings, while Demeter is characterized as someone who acts out of rage and hate.

Question 5
How does Proserpine's decision to eat the seeds of a pomegranate propel the action of the story?

Question 5 options:

Her action causes Zeus to fail to keep his promise.

Demeter then gets her daughter back.

It keeps her from ever returning from the underworld forever.

The seeds end up bringing winter to the world.

Q: Read the following excerpt from The Princess and the Goblin by George Macdonald. Then, answer the question that follows.

Perhaps you will wonder how the princess could tell that the old lady was an old lady, when I inform you that not only was she beautiful, but her skin was smooth and white. Her hair was combed back from her forehead and face, and hung loose far down and all over her back. That is not much like an old lady—is it? Ah! but it was white almost as snow. And although her face was so smooth, her eyes looked so wise that you could not have helped seeing she must be old. The princess, though she could not have told you why, did think her very old indeed—quite fifty, she said to herself.

i need help with my essay if its not too much to ask for.
i got removed from playing in band class so now i need to write essays on trumpets, trumpet players, etc for it.
this essay is about the origin of the trumpet. here's what i have so far:

The trumpet originated in Egypt and was either made of silver or bronze and was a sacred instrument to only be played in the worship of Egyptian god Osiris. The trumpet was later adopted by Israelites. A spin-off that was produced by Etruscan people was called the lituus. Unlike regular trumpets that were made from different types of metals, the lituus was made/carved from goat horns.

It was in an empty lot
Ringed by elms and fir and honeysuckle.
Bill Corson was pitching in his buckskin jacket,
Chuck Keller, fat even as a boy, was on first,
His t-shirt riding up over his gut,
Ron O'Neill, Jim, Dennis, were talking it up
In the field, a blue sky above them
Tipped with cirrus.

And there I was,
Just off the plane and plopped in the middle
Of Williamsport, Pa. and a neighborhood game,
Unnatural and without any moves,
My notions of baseball and America
Growing fuzzier each time I whiffed.

So it was not impossible that I,
Banished to the outfield and daydreaming
Of water, or a hotel in the mountains,
Would suddenly find myself in the path
Of a ball stung by Joe Barone.
I watched it closing in
Clean and untouched, transfixed
By its easy arc before it hit
My forehead with a thud.

I fell back,
Dazed, clutching my brow,
Groaning, "Oh my shin, oh my shin,"
And everybody peeled away from me
And dropped from laughter, and there we were,
All of us writhing on the ground for one reason
Or another.

Someone said "shin" again,
There was a wild stamping of hands on the ground,
A kicking of feet, and the fit
Of laughter overtook me too,
And that was important, as important
As Joe Barone asking me how I was
Through his tears, picking me up
And dusting me off with hands like swatters, And though my head felt heavy,
I played on till dusk
Missing flies and pop-ups and grounders
And calling out in desperation things like
"Yours" and "take it," but doing all right,
Tugging at my cap in just the right way,
Crouching low, my feet set,
"Hum baby" sweetly on my lips.

Mom’s Promise

Jasmine and Jeremiah’s mom was dedicated to her children. She taxied them back and forth to school, dance classes, soccer practice, and any other activity they wanted to do — basically, if the kids had a desire to pursue it, their mom would find a way to make it happen.
Of course, there were times that Jasmine and Jeremiah couldn’t get what they yearned for. For instance, one summer, Jasmine and Jeremiah begged to visit a large amusement park that they kept seeing advertised on TV, but their mom knew it was beyond their budget for vacation that year. She told them she would do everything she could to make their vacation dream come to fruition the next year, but she made “no promises.”
At the time, Jasmine was vexed. She rolled her eyes as she reflected on how her mom had never kept a promise in her life! But that wasn’t true — it wasn't that Mom didn't keep promises. She had never actually made a promise to Jasmine and Jeremiah.
Before the kids were born, Jasmine and Jeremiah's mom made an oath to herself. She knew that it would be important to instill a sense of honesty in her children. She wanted them to know the importance of being trustworthy — and she also knew if she made promises she didn’t keep, her children would not have confidence in her. They wouldn’t depend on her because they wouldn’t know if they could actually rely on her.
Mom never wanted that to happen, so once Jasmine and Jeremiah were around, she avoided ever making promises.
Of course, the kids would try to trick her — sometimes, they would try to get Mom to promise something really simple that seemed to guarantee to happen! There was no danger in making a promise that she would keep, right? But every time, Mom would still refuse.
Sometimes, on Thursday nights, Jeremiah would ask Mom if they could have pizza for dinner the following night. He knew that they had a family pizza night every Friday, but he wanted to try to scheme his mom into making a promise.
When Mom agreed — with a smile, of course, since she knew their tricks — Jeremiah would grin back and ask, “Promise?”
But Mom wouldn’t promise — and anytime they asked her to, she would reply with a loving, “I’ll try my best.”
One day, when Jasmine and Jeremiah interrogated Mom about why she wouldn’t make a promise, she explained it like this: “I want you to always trust me, and I want you to know that I mean what I say. But sometimes, things are out of our control; nothing in life is guaranteed. I might want to tell you something is definite, but there are some circumstances out of our control. I never want to break a promise to you, and the only way to guarantee I don’t break a promise is to never make one.”
Mom put her hands on Jasmine and Jeremiah’s shoulders. “I will make you one promise, but it’s the only one I’ll make. I promise I will always try my best.”

PLEASE HELP!

Emma was having a wonderful time at summer camp. She’d made friends with
all the girls in her cabin, and she was having taking part in all the activities, and
she even secretly enjoyed some of the chores.
One day, a package arrived at camp from Emma’s grandmother. The other girls
in the cabin were excited about what the package contained, and watched as
Emma opened it. Inside was a box of her grandmother’s homemade caramels,
which were Emma’s favorite. She was about to eat one of them when one of the
other girls asked if she could have a caramel. Then the other girls asked the
same question. Emma counted the caramels. There were ten in the box. There
were eight other girls in the cabin, so if she gave each of them one caramel,
there would only be two left for her. She thought about keeping them for herself.
After all, they were her favorite, and her grandmother had sent them to her. As
much as she loved the caramels, though, she also wanted her friends to get a
chance to try them. So she gave each girl a caramel. That night they all got a
treat, and Emma was glad she’d shared her favorite treat with her new friends.

with the door closed.
I have to learn how to dance
in time for the next party
my room is too small for me
suppose I die before graduation
they will sing sad melodies
but finally
tell the truth about me
There is nothing I want to do
and too much
that has to be done
and momma’s in the bedroom
with the door closed.
Nobody even stops to think
about my side of it
I should have been on Math Team
my marks were better than his
why do I have to be

wearing braces
I have nothing to wear tomorrow
will I live long enough
to grow up
and momma’s in the bedroom

The author probably wrote this article in order to __________.
A.Explain why cosmetic surgeons are researching limb replacement
B.Suggest that a bionic hand could not be made to look like a natural one
C.Highlight the differences between a bionic hand and a natural one
D.Inform readers about the development of bionic hands for three men


Milorad Marinkovic, age 30, lost the use of his right hand in a motorcycle accident in 2001. He never thought he'd be able to control a prosthetic as naturally as he controlled his unaffected hand. Neither did his doctors. But in 2011, Marinkovic replaced his injured hand with a bionic one. It responds to thought, just as a natural hand does.


The patients then needed to learn to use faint signals from those nerves to command the artificial hand. Now, the men use their new, bionic hands to perform everyday tasks. They can pick up a ball, handle small items like coat buttons and shoelaces, and cut food with a knife.


Previously, people with bionic hands have primarily controlled them with manual settings. But with the new groundbreaking technique, the transplanted nerves allow the brain to relay messages directly to the new extremity. It's particularly notable since the human hand contains sophisticated muscle structures and a complex nerve system, making it especially difficult to copy.


Dr. Oskar Aszmann of the Medical University of Vienna developed the bionic reconstruction approach with some of his coworkers. He performed the first surgery in April 2011 on an Austrian named Patrick, then age 24. (Patrick declined to give his last name.) He had lost the use of his left hand as the result of a work injury three years earlier.



"This is the first time we have bionically reconstructed a hand," Dr. Aszmann said at the time. "If I saw these kinds of patients five to seven years ago, I would have just shrugged my shoulders and said, 'There's nothing I can do for you.'"




Aszmann's team described the cases of the three men in a report published in the journal Lancet in February 2015. All three men had suffered injuries to the brachial plexus. This is a network of nerves running from the spine to the shoulder, arm, forearm, and hand, and it controls movement in these areas.




Injuries had left the hands of these men paralyzed. They opted to undergo the elective amputation only after having the bionic hand strapped onto their injured hand. This allowed them to see how the robotic one might work.



Now, after the surgery, Marinkovic loves his new hand. It allows him to hold things like a sandwich or a bottle of water—and most importantly, to play with his three children. Still, the bionic hand is not the same as a natural one.

A.Teens Having Trouble Hearing Consonants
B.Hearing Loss Affects Mathew Brady's Life
C.Teens Using Music Devices in Greater Numbers
D.Hearing Loss On the Rise Among Teens

BOSTON, Massachusetts. A recent study revealed that one in five teenagers has at least some hearing loss. The rate of hearing loss among young people has grown significantly since about 1990. Now, experts are urging kids to turn down the volume on their digital music players. These experts suggest that listening to loud music through earbuds may be responsible for the increase.

For the study, researchers compared data from two nationwide health surveys of hearing loss in 12- to 19-year-olds. The first study was done between 1988 and 1994. The second was done between 2005 and 2006. In the first study, about 15 percent of teens were found to have at least some hearing loss. In the more recent study, 19.5 percent of teens had at least some hearing loss. This means that about 6.5 million young people have at least some difficulty hearing.

Most of the hearing loss in the teens was "slight." Researchers defined "slight" as an inability to hear at 16 to 24 decibels. A teen with slight hearing loss might not be able to hear sounds such as leaves rustling or someone whispering. Dr. Gary Curhan was the study's senior author. According to Curhan, people with slight hearing loss can hear vowel sounds clearly. However, they might miss sounds from some consonants, such as t, k, and s. Experts warn that this minor loss of hearing is sufficient to cause problems in school. It also sets the stage for hearing aids later in life.

"Although speech will be detectable, it might not be fully intelligible," Curhan said. Researchers lack final evidence that listening to iPods and other music devices is to blame for hearing loss in teens. However, researchers did note a significant increase in high-frequency hearing loss. This particular type of hearing loss, researchers said, indicates that noise may be to blame. Researchers cited a 2010 Australian study. The study linked the use of personal listening devices with a 70 percent increased risk of hearing loss in young people.

"I think the evidence is out there that prolonged exposure to loud noise is likely to be harmful to hearing, but that doesn't mean kids can't listen to MP3 players," Curhan said. "Our hope is we can encourage people to be careful."

Loud music isn't anything new, of course. Each recent generation of teens has found a new technology to blast music. Teens listened to bulky headphones in the 1960s and used the handheld Sony Walkmans in the 1980s. Today's teens, however, spend more time than ever listening to music. In fact, according to audiologist Brian Fligor, young people spend more than twice as much time listening to music than previous generations.

One of Fligor's patients is 17-year-old Matthew Brady of Foxborough, Massachusetts. Matthew has a mild hearing loss. He has trouble hearing his friends in the school cafeteria. He has admitted to occasionally faking comprehension. Matthew used to listen to an iPod turned up too loud and for too long. Fligor believes this caused Matthew's muffled hearing.

Matthew used to crank up the volume on his favorites—Daughtry, Bon Jovi, and U2—while walking on a treadmill. He did this at least four days a week for 30-minute stretches at a time. One day last summer, he got off the treadmill and couldn't hear anything with his left ear. His hearing gradually returned, but it was never the same.

Matthew's fondness for listening to loud music in not uncommon. During a study of college students, Fligor found that more than half of those tested listened to music at 85 decibels or louder. That's about as loud as a hair dryer or a vacuum cleaner. According to Fligor, regular listening at those levels can turn microscopic hair cells in the inner ear into scar tissue. Fligor believes that some people, such as Matthew, may be more likely to experience damage than others.

These days, Matthew still listens to his digital music player. But now he listens at lower volumes.

"Do not [blast] your iPod," Matthew cautions other teens. "It's only going to hurt your hearing. I learned this the hard way."
