Is 2,000 a good estimate for the difference between 4,315 and 156? If it is, explain why it is a good estimate. If it is not, explain why it is a bad estimate.

Answers

Answer 1

Answer:

2000 is not a good estimate for the difference of 4315 and 156.

Explanation:

For a number to be a good estimate between the sum or the difference between two numbers, those numbers must be close to the actual result.

Following this reasoning, we can say that 2000 is not a good estimate for the difference between 4315 and 156, since this difference results in 4159, which is a number very far from 2000.

C. They simulated natural conversation.
D. They made poems easier to memorize.
SUBMIT

Answers

The correct answer is D. They made poems easier to memorize.

Explanation:

In poems, alliteration refers to using words with the same consonant sound in a verse or multiple verses. This device makes the poem more memorable or easy to remember as the repetition forms a sound pattern. Also, by remembering which consonant sound is repeated it is easy to remember the words of each verse. Similarly, the use of the meter or a specific structure of verses (number of syllables in each verse and organization of stressed/unstressed syllables) makes the poem to be predictable and easy to remember. Moreover, these two features were more commonly used in poems during the 14th and 15th centuries as in this way the audience could better remember poems.

"Trying to understand these characters exercises the same mental muscle that helps us understand people in the real world." "He studies the effect reading fiction and nonfiction has on our ability to understand what others are feeling." plz hurry

Answers

Answer:

B). "He found that children and adults who have read stories their whole lives were more likely to correctly identify the feelings and thoughts of others than those who do not read regularly."

C). "Trying to understand these characters exercises the same mental muscle that helps us understand people in the real world."

Explanation:

The above two evidence factually support and substantiate the claim that 'people who read stories are better at communicating and understanding the feelings of others.'

The first evidence i.e. option B states that the research revealed 'the children or adults who have been reading stories constantly their whole lives are able to recognize the thoughts or feelings of others more accurately' while the second evidence i.e. option C asserts logically that 'in attempt to understand the characters of stories, the same mental muscle is required for understanding people in real life.'

Thus, these two pieces of evidence not only support but substantiates how reading comprehends our understanding of thoughts, opinions, or feelings of others. Hence, options B and C are the correct answers.

Read the following paragraph from “Nevada Moose Herds Growing,” an article written by Benjamin Spillman on page 1A in the October 18, 2017 edition of the Reno Gazette-Journal: Given the limited amount of viable moose habitat in Nevada, the driest state in the U.S., it’s likely the population is small. But the Nevada Department of Wildlife wants to alert the public to keep people from shooting them. Which of the options below most correctly and effectively incorporates this source material? (Either APA or MLA style citations are acceptable.) In his article “Nevada Moose Herds Growing,” Spillman notes that the Nevada Department of Wildlife doesn’t want people “shooting” moose because their population “is small” (1A). Although the “Nevada moose herds growing,” that doesn’t mean you should shoot them (Spillman 1A). Nevada is too dry to support a large moose herd, but their population is growing. (Nevada Department of Wildlife 1A). It’s a sad state of affairs when NDOW announces a rare animal sighting not so we can enjoy them but to “keep people from shooting them” (Spillman 1A).

Answers

The correct answer is in the sentence "It's a sad state of affairs when NDOW [...] them but to “keep people from shooting them” (Spillman 1A)," as shown in the last answer option.

How does the sentence incorporate the source material effectively?Paraphrasing the source material.Avoiding plagiarism.Giving credit to the author of the source material.Highlighting the author's words.

The last answer option shows how a paraphrase of the original material was made, where the author used the meaning of the original text to create another text, with other words.

However, when using words spoken by the author of the original text, the author of the paraphrase highlighted them by putting them in quotation marks and giving credits to the original author.

Read the following sentence. Last year, the council members blank happy to visit their sister city in Argentina. Choose the verb that makes this sentence correct. a. were b. are c. was d. is

Answers

The correct answer is A. Were

Explanation:

Verbs should agree with the subject (person or entity doing the action) and they should be in the correct tense (present, past, or future). In this context, the section "Last year" indicates the action of the sentence occurred in the past, and therefore the verb should be in the past. Moreover, in this sentence, the subject is "the council members", which is a plural subject. This means an appropriate verb for this sentence should be in past and plural form. According to this, the only correct option is "were" because this is the past form of the verb to be, it is used for plural subjects, and it creates a coherent sentence.

The first stanza of “On Being Brought from Africa,” introduces a paradox. Using evidence from the poem, describe the paradox.

Answers

Answer:

“On Being Brought from Africa”

Paradox in the first stanza:

Phillis described her enslavement as a means of her salvation.  Thus, she was brought to America so that her soul could be saved.  Those who enslaved her, saved her.  This ordinarily sounds difficult to understand and contradictory.  How can somebody who kill you make you alive?  This is a paradox which can only be appreciated in the light of the Christian gospel.  Christ died and rose again from the dead.  Because He has risen, He is able to save those who die in sin.

This is the central message of Phillis' poem titled "On Being Brought from Africa."  In her own words:

 "Twas mercy brought me from my Pagan land,

  Taught my benighted soul to understand  

  That there's a God, that there's a Saviour too:

  Once I redemption neither sought nor knew. "

Evil was turned to good in her life.  She was not complaining against her enslavement or being removed from her African root, friends, and family.  She eulogized God who has the ultimate power to bring about good from evil.  Though, she was not praising evil, she knew and therefore, understood, and greatly benefited from the evil done to her, and even appreciated those who did her evil for doing her good.

This should be the attitude of all Africans, including African Americans, and this should be how they must view their past.  Slavery was a condemnable evil.  But, God has turned it to good.  Africans should stop lamenting their past enslavement.  They should henceforth make themselves free and live in freedom.  They should not retreat to their past.  The past is history.  It is not the future of Africa.  They should appreciate that, though, enslavery derived them of temporary freedom, it has brought lasting freedom.  Freedom is only achieved in Christ Jesus, in walking the talk, and not in blaming the past or past actors.  Olaudah Equiano bought his freedom within three years.  For more than 50 years now, Africans have been in charge of their governments and their borders, but what have they achieved with the leadership?  They are still leading the people back to slavery in so many absurd ways.

Explanation:

Phillis Wheatley wrote "On Being Brought from Africa" in 1773.  She is recognized as the first African American woman to publish a book in English.

The paradox is that black people are seen as sinful beings, even if they accept and practice Christian concepts and doctrines.

We can arrive at this answer because:

Paradox is the figure of speech that presents two contrary ideas, which cancel each other out as true and coexisting ideas.In “On Being Brought from Africa,” we can see an example of this figure of speech when the speaker forms that black people were forced to adopt Christianity when they were pulled out of Africa and imprisoned in America.However, even though they are Christians and practice Christianity, black people are seen as sinful and pagan people.

In this case, we can see that the paradox in this poem shows that even Christians, blacks are seen as beings turned to sin.
