Question: What are the differences between Deza’s old school in Gary, Indiana, and her new school in Flint, Michigan? Cite text evidence to support your answer.


Text: From Chapter Twenty-Two: Learning How to Settle in Flint I’d been having such a good time being Little Stew and trying to fill in all the missing words from the Reader’s Digest that time had completely run off and forgot all about me! “But, Mother, Miss Stew needs me to—” “You aren’t suggesting you stay here and help Stew instead of going to school, are you?” When she said it like that, it did seem silly. ***On the outside, schools in Flint seemed a lot like schools in Gary, but they weren’t. Instead of having one teacher all day, in Flint we went from classroom to classroom and teacher to teacher for each subject. The teachers were different too. First, all of them were white, and second, they weren’t anywhere as nice as the teachers in Gary. But one of Mrs. Needham’s lessons stuck: I was learning how to toughen up. I got my usual As on the tests in mathematics, geography, civics and history. After my first mathematics test, when class was dismissed, Mrs. Scott called me to her desk. “Deza, have you always done so well in math? You’re the only student who got a perfect score.” I sounded very humble, but the truth’s the truth. “Yes, ma’am. Mathematics is one of my favorite subjects.” It was great to be back in school! “Could I ask you a favor?” Maybe she wanted me to help some of my classmates. Even though they were white, some of them were the spittin’ image of Dolly Peaches and Benny Cobb. She slid a paper toward me. It had five unsolved story problems on it. “Could you sit right there, right now, and solve these for me?” Maybe Mrs. Scott was seeing if I was ready for harder work. I finished in no time. She looked them over. “Hmm, perfect again, but next time you must make sure to show all your work. You’re dismissed.” I was surprised that was all she said. In English class I really showed how much I’d toughened up. Flint teachers don’t have the imaginations that Gary teachers do, so instead of giving grades back so everyone knows what you got, they walk around the class and hand your test or paper back to you. Upside down. Mr. Smith was passing out our first essay. I’d followed all of Mrs. Needham’s advice. I’d written it at the Flint Public Library and was very careful not to use the dictionary or the thesaurus too much. And I didn’t digress at all. I made sure my posture was good, crossed my ankles and folded my hands on the desk when he got close to me. He handed me my paper and smiled. “Very good job.” My heart flew! “Thank you, sir.” I turned my paper over. He’d written, “Good for you!” and put a giant C+ with three exclamation points. I turned the paper back over. Maybe I saw it wrong. I looked again but it was the same. One sign that I had toughened up was that instead of crying I thought of a little joke that Jimmie said he did whenever he didn’t like his grade. “I turn the paper over, then, the same way people bang on a machine it if ain’t acting right, I smack my hand on the paper. Maybe if I bang it hard enough my grade will jump up a mark!” It was nonsense, but I slapped my hand on Mr. Smith’s essay. I turned the paper back over and smiled. I’d have to tell Jimmie that it still wasn’t working. Mrs. Needham would’ve been proud. Instead of bawling, I looked at Mr. Smith’s back and said to myself, “OK, buster, I’m going to make sure my next essay is the best thing I’ve ever written. You won’t have any choice but to give me my A plus.” When me and Loretta were walking back to camp I asked, “What grade did you get on your essay?” “I don’t know, the same old D. What’d you get?” “C plus.” She stopped walking. “Uh-oh, no, you didn’t!” I showed her my grade. “Ooh, girl, you must be real smart.” “For getting a C plus?” “All these teachers up here at Whittier’s prejudice. Katherine Williams was the smartest colored girl in the school and all she use to get was a C. You must be a genius to get a C plus!” She laughed. “I’m gonna see if I can sit next to you when we take our next exam!”

According to the text, even though the schools in Flint seemed like those in Gary, there were some differences.

These differences were:

The schools in Flint required the students to move from one class room to another classroom and also each of the teachers were different. This is in contrast to the Gary where students have only one teacher all day.Secondly all the teachers in Flint were white compare to Gary that was mixed.Thirdly the teachers in Flint were not as nice as the teachers in Gary

Read the following excerpt from the article "Vision, Voice and the Power of Creation: An Author Speaks Out," by T. A. Barron, and answer the question that follows:

Another way to tap the power of imagination is through place. My own background as a writer is rooted in nature, having grown up reading Henry David Thoreau, Rachel Carson, and John Muir long before I ever dipped into Madeleine L'Engle, Lloyd Alexander, Ursula Le Guin, E. B. White, or J.R.R. Tolkien. My early writings were really nature journals; at nine, I wrote a complete biography—of a tree. (It was a once-majestic chestnut tree not far from my home.) So it should come as no surprise that I view place as much more than just a setting for a story. It is, in truth, another form of character, no less alive and complex, mysterious and contradictory, than the richest character in human form.

What does this paragraph imply about the way the author would treat the setting in his work?

What can we do to help end child labor around the world?

Answers

Answer:

Well, the change has to start within each one of us, and that ends when all children are free to be children. There is honestly no clear, global definition of child labor. In one book "Living as a Child Laborer has made this distinction: Child Labor is “work that is mentally, physically, socially, or morally dangerous and harmful to children or interferes with their education. It is work, therefore, that deprives children of their childhood, their potential, and their dignity.”

Read the stanza from "The Battle of Blenheim." "And everybody praised the Duke Who this great fight did win." "But what good came of it at last?" Quoth little Peterkin. "Why that I cannot tell," said he, "But 'twas a famous victory." How does Robert Southey's word choice affect the tone in this stanza of the poem?

It creates an ironic and sarcastic tone.

It suggests a hopeful and sincere tone.

It creates a sad and mournful tone.

It suggests a honest and matter-of-fact tone.

Answers

Answer:

It suggests a honest and matter-of-fact tone.

Explanation:

In this poem by Robert Southey, the poet narrates the events of the battle of Blenheim to his granddaughter. His tone was suggestive of an honest and matter-of-fact evaluation of the matter. He was honest enough to explain that he did not really know why the battle was fought or if any good came of it.

Honesty in this case required not buttering up the matter or saying what a person was not really sure of. In a matter-of-fact tone, he acknowledged that it was a famous battle.
