In an engine, fuel and oxygen chemically react and release energy. What happens to the energy NOT used by the engine?
A.
It has been destroyed.
B.
It is lost in the form of heat and sound.
C.
It remains stored in the chemical bonds of the fuel.
D.
It is converted into methane.
what is the correct answer?
please double check
The correct answer is B. It is lost in the form of heat and sound.
To determine the correct answer, let's analyze the options:
A. It has been destroyed: Energy cannot be created or destroyed according to the law of conservation of energy. So, this option is incorrect.
B. It is lost in the form of heat and sound: This option is commonly true for many engines. Not all of the released energy can be effectively converted into useful work, so a significant portion of it is usually lost as heat and sound. Therefore, this option could be correct.
C. It remains stored in the chemical bonds of the fuel: After the chemical reaction between fuel and oxygen, the energy is released. However, this option doesn't address what happens to the energy that is not used by the engine. So, this option is likely incorrect.
D. It is converted into methane: This option implies that the unused energy is transformed into an entirely different substance, which is not typical of most engines. So, this option is likely incorrect.
Based on this analysis, option B, "It is lost in the form of heat and sound," is likely the correct answer.
The correct answer is B. It is lost in the form of heat and sound.
Below is an excerpt from an informational essay that a student wrote.
Based on a recent study, school lunches have been shown to be an important factor for students in schools. Students that eat a healthy lunch perform better on high stakes tests and are reportedly healthier and happier. Furthermore, good nutrition is important for children in the developmental process. So really, it's pretty obvious how important it is to make school lunches number one!
Which of the following is the best way to revise the underlined sentence for appropriate language while maintaining the same meaning?
A.
Really, it is pretty obvious how badly we need to do something with lunches.
B.
In conclusion, it is important that schools prioritize nutrition in order to maximize the benefits to children.
C.
We need to do something, because obviously we need better lunches badly.
D.
Students perform better at a statistically significant level when they are provided with something to eat.
The best way to revise the underlined sentence for appropriate language while maintaining the same meaning is option B: "In conclusion, it is important that schools prioritize nutrition in order to maximize the benefits to children."
This revised sentence maintains the focus on the importance of school lunches but presents it in a more formal and objective manner. It avoids the use of slang ("pretty obvious"), provides a more concise summary of the main idea, and maintains a professional tone appropriate for an informational essay.
Which sentence in the first paragraph should be removed because it does not relate to the main idea?
A.
sentence 2
B.
sentence 3
C.
sentence 4
D.
sentence 5

(4) When people are in the harbor, they are near this marvelous symbol of liberty. (5) I saw this statue and will never forget it. (6) What they may not know is that creating the statue took many years and effort to complete.
what is the correct answer?
read the paragraph then answer the question
Based on the given paragraph, the sentence that should be removed because it does not relate to the main idea is sentence 5: "I saw this statue and will never forget it." This sentence is a personal anecdote from the author and does not contribute to the main idea of providing information about the Statue of Liberty, its location, and its significance.
Read the following sentence from the passage "A Gift of Admiration."
What they may not know is that creating the statue took many years and effort to complete.
How should the sentence be revised to create a more formal tone?
A.
To many the creation of the statue was not known because it took many years and much effort to complete.
B.
What many do not know, is that creating the statue took many years and much effort to complete.
C.
Not known by them, is that the creation of the statue took lots of years and much effort to complete.
what is the correct answer?
please double check
The correct answer is B.
"What many do not know is that creating the statue took many years and much effort to complete."
This revision presents the information in a more formal tone by using proper grammar and removing unnecessary phrases ("To many," "Not known by them") that can make the sentence sound informal or awkward.
A student is writing a report and wants to edit it to make better transitions among the paragraphs. Read the students report and answer the question that follows.
President Abraham Lincoln delivered the Gettysburg Address in 1863 at the dedication of the Soldiers' National Cemetery in Pennsylvania. The first speaker at the dedication, Edward Everett, orated for more than two hours. President Lincoln spoke after him, and his speech lasted little more than two minutes. Afterward, Everett told Lincoln that he wished he could express in two hours what Lincoln had said in two minutes.
Lincoln had delivered one of the most memorable speeches in history. This was fitting, as over 50,000 soldiers had died at the Battle of Gettysburg, a turning point in the Civil War. Lincoln's speech focused on a "new birth of freedom" in the United States, as he invoked the Declaration of Independence and its principles of liberty and equality. He stated clearly the need for the nation to be both united and free.
The oldest copies of the speech are different from one another. The Library of Congress has two copies, and the others were recorded by Lincoln well after the speech. One copy was made for Everett, but "Bancroft" and "Bliss" versions also exist. The "Bliss" version is carved into a wall of the Lincoln Memorial in our nation's capital.
Choose the sentence that provides the BEST transition between paragraphs 2 and 3.
A.
It is not exactly certain which words Lincoln spoke that day.
B.
The spirit of Lincoln's speech is remembered well today.
C.
Lincoln was certain about his vision for the course of the nation.
D.
Lincoln's speech had surprised the crowd.
analyze and then give the correct answer
After analyzing the paragraphs, the sentence that provides the best transition between paragraphs 2 and 3 is option A: "It is not exactly certain which words Lincoln spoke that day."
This transition sentence connects the topic of Lincoln's speech and the various copies of it. It indicates that there is uncertainty about the exact words Lincoln spoke, which leads into the subsequent paragraph discussing the different versions of the speech.
Read the following sentence.
Jack's words burned Anna and she cried for days.
Which of following best explains what happened when "Jack's words burned Anna"?
A.
Jack yelled at Anna.
B.
Jack's words hurt Anna's feelings.
C.
Jack's words set fire to Anna.
read and then give the correct answer
Based on the information provided, the best explanation for what happened when "Jack's words burned Anna" is option B: Jack's words hurt Anna's feelings.
The use of the word "burned" in this context is metaphorical. It suggests that Jack's words had a strong and painful emotional impact on Anna, resulting in her experiencing emotional distress and crying for days. Option A implies a physical act of yelling, which may not be the case based on the given sentence. Option C is not feasible as it suggests a literal fire caused by words, which is not the intended meaning. Therefore, option B is the correct answer.
In which sentence does the underlined word have the most negative connotation?
A.
Three years later, Carlos and his men returned from the long journey.
B.
Three years later, Carlos and his men returned from the grueling journey.
C.
Three years later, Carlos and his men returned from the brief journey.
D.
Three years later, Carlos and his men returned from the painless journey.
The sentence in which the underlined word has the most negative connotation is B: "Three years later, Carlos and his men returned from the grueling journey."
The word "grueling" conveys a negative connotation, suggesting that the journey was extremely difficult, exhausting, and perhaps even torturous. This emphasizes the challenging nature of the journey and implies that it was filled with hardship and suffering. Options A, C, and D either do not have a negative connotation (A and C) or have a positive connotation (D).
Identify the correct explanation of the underlined IDIOM in the sentence below.
The group members said that the homework assignment was as easy as pie.
A.
difficult to achieve
B.
enjoyable and fun
C.
quick and effortless
D.
boring and dull
The correct explanation of the underlined idiom in the sentence "The group members said that the homework assignment was as easy as pie" is C: quick and effortless.
The idiom "easy as pie" is commonly used to describe something that is very easy to do or accomplish. It suggests that the homework assignment was not challenging and required little effort on the part of the group members. Option A, difficult to achieve, is the opposite of the intended meaning. Option B, enjoyable and fun, and option D, boring and dull, are not accurate interpretations of the idiom in this context.
What does loathe mean as it is used in these lines from "The Diary of Anne Frank"?
I don't think I shall ever feel really at home in this house, but that does not mean that I loathe it here, it is more like being on vacation in a very peculiar boardinghouse.
A.
enjoy
B.
like
C.
indifferent
D.
despise
In the given context from "The Diary of Anne Frank," the word "loathe" means option C: indifferent.
Anne Frank clarifies that although she does not feel completely at home in the house, it does not imply that she despises it. Instead, she compares her living situation to being on vacation in a peculiar boarding house, suggesting a sense of distance or lack of deep attachment. Option A, enjoy, and option B, like, are too positive to accurately capture the meaning. Option D, despise, is too extreme and does not align with Anne's ambivalent feelings towards the house.
Read the following sentence from the passage
I don't think I shall ever feel really at home in this house, but that does not mean that I loathe it here, it is more like being on vacation in a very peculiar boardinghouse.
Which of following best describes the connotative meaning of the word home as it is used in the sentence above?
A.
a residence
B.
a base
C.
a feeling of comfort
D.
an institution where people are cared for
In the sentence provided, the connotative meaning of the word "home" suggests option C: a feeling of comfort.
While "home" can refer to a physical residence (option A), it carries a more emotional and personal connotation in this context. Anne Frank expresses that she doesn't feel truly at ease or comfortable in this house, indicating that the emotional connection and sense of security associated with "home" are not present. Option B, a base, is related to a physical location and doesn't capture the emotional aspect of "home." Option D, an institution where people are cared for, does not align with the meaning in this sentence.
Read the following paragraph.
Physical activity helps improve the overall health of individuals. It assists with circulation, increases blood flow to the brain, and can raise endorphin levels. Essentially, all of these things help reduce stress, improve mood, and can help students achieve more academically. Studies have shown that providing students with a designated time for physical activity in school can lead to better concentration, reduce disruptive behaviors, and help students achieve higher test scores in reading, math, and writing. Despite all the positives that physical education may have, only 8% of elementary schools, 6.4% of middle schools, and 5.8% of high schools provide daily physical education to their students. The National Association for Sport and Physical Education recommend students engage in at least 60 minutes of physical activity each day; however, it is more likely that students will only engage in 16–18 minutes.
Which opinion could be generated using the evidence the author included?
A.
States should enforce stricter physical education requirements in their schools.
B.
Students should spend more time in the classroom to ensure higher achievement.
C.
Students should steer away from physical activity and spend time studying.
D.
Parents should require their children to exercise at home every day.
read and then provide the correct answer
Based on the evidence provided in the paragraph, the opinion that could be generated is option A: States should enforce stricter physical education requirements in their schools.
The paragraph presents several points highlighting the positive effects of physical activity on students' health and academic achievement. It also mentions the low percentages of schools that currently offer daily physical education. Considering the evidence, one could reasonably conclude that enforcing stricter physical education requirements in schools would be a beneficial course of action to improve student health and academic performance. Options B, C, and D are not supported by the evidence presented in the paragraph.
