Answer:

Answer to 3 is given below

Step-by-step explanation:

3. The passage contains an example of anaphora, which is the repetition of the phrase "it takes" at the beginning of each sentence. This repetition emphasizes the importance of each group mentioned in the passage and reinforces the idea that raising a happy, healthy, and hopeful child requires the involvement and collaboration of multiple individuals and groups.

The passage does not contain an example of alliteration, which is the repetition of the same sound at the beginning of multiple words.

Answer:

Answers explained below.

Step-by-step explanation:

1. One way to ensure that space resources are used to benefit all people is through international cooperation and agreements that promote the sharing and equitable distribution of resources. Additionally, having a clear set of laws and regulations in place for the use and exploration of space resources can help to prevent any one country or organization from monopolizing them. Additionally, encouraging private companies to invest in space exploration and resource utilization can also help to ensure that the benefits of space resources are spread widely.

2. The question of whether humans have the right to take resources from other parts of the solar system is a complex one, as it is not yet clear whether there are any resources that can be extracted from other celestial bodies, and there is no universally accepted framework for determining property rights in space.

Some argue that space resources should be considered the common heritage of mankind, and that their exploitation should be regulated through international agreements to ensure that they are used for the benefit of all humanity. Others argue that countries and private companies should be able to claim ownership of resources they extract from space, similar to how resources on Earth are claimed.

Currently, the Outer Space Treaty of 1967, ratified by 110 countries, states that outer space is not subject to national appropriation, and celestial bodies are not subject to ownership. And any activities in outer space should be carried out for the benefit and in the interests of all countries and shall be the province of all mankind.

It is a topic of ongoing discussion and debate among legal experts, policymakers, and scientists.

3. The question of whether humans have the right to invade other unique environments around the solar system is also a complex and controversial one.

Some argue that humans have a moral and scientific obligation to explore and study other celestial bodies in order to gain a better understanding of the universe and our place in it. They may also argue that we have a responsibility to search for potential resources and habitable environments that could support human life in the future.

On the other hand, others argue that humans should not invade other unique environments around the solar system as it would be disrespectful to the unique and fragile ecosystems that may exist on other celestial bodies and could also contaminate them with Earth-borne organisms.

4. Some ways to achieve this include:

International cooperation and agreements: Establishing international agreements and protocols that promote the sharing and equitable distribution of space resources can help to ensure that the benefits of these resources are spread widely among all countries.

Transparency and regulation: Having a clear set of laws and regulations in place for the use and exploration of space resources can help to prevent any one country or organization from monopolizing them and ensure that they are being used in the public interest.

Encouraging private companies: Encouraging private companies to invest in space exploration and resource utilization can also help to ensure that the benefits of space resources are spread widely, as private companies are more likely to operate in a competitive market.

Space governance: Establishing a proper governance and regulatory framework to govern the use of space resources and activities, it would help to prevent countries from weaponizing space and avoid any kind of conflict.

Public awareness: Raising public awareness about the potential benefits and challenges of space exploration and resource utilization can help to ensure that the public is involved in the decision-making process and that the benefits of space resources are distributed equitably.

5. There are certainly many problems on Earth that could be solved with the money now used for space programs. Some examples include:

Poverty and inequality: Funding programs that aim to reduce poverty and inequality, such as providing access to education, healthcare, and basic needs like food, shelter, and clean water.

Climate change: Investing in renewable energy sources, developing sustainable infrastructure and transportation systems, and funding research into climate change mitigation and adaptation.

Health and medical research: Funding research into diseases, such as cancer and infectious diseases, as well as providing access to basic healthcare services.

Infrastructure and transportation: Upgrading and building infrastructure, such as roads, bridges, and public transportation systems, which would provide jobs and improve the quality of life for many people.

Education: Investing in education, including providing access to primary and secondary education, as well as higher education and vocational training.

6. The space program has led to the development of a wide range of skills, careers, and programs, including:

Engineering: The space program has led to the development of new technologies, such as propulsion systems, materials, and robotics. This has created job opportunities for engineers who specialize in these areas.

Science: The space program has led to advances in fields such as astronomy, planetary science, and earth observation. This has created opportunities for scientists to study the universe, the solar system and earth from space.

Aerospace: The space program has led to the development of new aerospace technologies, such as satellites, rockets, and spacecraft. This has created job opportunities for aerospace engineers and technicians.

Computer science: The space program relies heavily on computer science, such as software development, data analysis, and artificial intelligence.

Medicine: Space programs have led to the development of new medical technologies, such as radiation protection, life support systems, and telemedicine. This has created opportunities for medical professionals to specialize in space medicine.

Business: Space programs also generate business opportunities, from space tourism, launching commercial payloads, to satellite-based services.

Answer:

Answer explained below.

Step-by-step explanation:

Note - I am solving the first 5 questions.

1. 

In "Why I Write," Joan Didion explains that she stole the title of her essay from George Orwell's essay of the same name because she found it an "enormously suggestive" phrase (paragraph 1). She wanted to explore the question of why writers write, and Orwell's title seemed to encapsulate that idea perfectly. Didion acknowledges that Orwell's essay was not the only inspiration for her own; she also mentions Henry James's preface to "The Ambassadors" and her own personal experiences as a writer. However, she uses Orwell's title as a starting point for her own reflections on the writing process.

Evidence: "The title "Why I Write" attracted me because I was interested in the larger question. Why do writers write? And in particular, why do I write?" (paragraph 1)

2. 

Joan Didion describes her experience as an English major at UC Berkeley as somewhat unsatisfying. She writes that she did not learn much about writing during her time there and that her education was focused more on literary criticism than on the craft of writing itself. She also notes that her interest in writing was seen as somewhat unconventional for a woman at the time.

Evidence: "At Berkeley in the 1950s, when I was an undergraduate, the requirements for the English major were severe, and the prerequisites daunting. [...] I was not in love with the idea of being a journalist, nor was I particularly in love with the idea of being an academic, but I was in love with the idea of being a writer. I did not decide to be a writer. I discovered I was one" (paragraph 3).

3. 

When Joan Didion writes "Grammar is a piano I play by ear" (paragraph 9), she means that she has an intuitive sense of how to use grammar and syntax, rather than a strictly rule-bound approach. She believes that "good writing" has a certain rhythm to it, and that her ear for that rhythm is more important than strict adherence to grammatical rules. She cites Ernest Hemingway and Henry James as examples of writers who had a similar approach to grammar.

Evidence: "I am a writer who came of a sheltered life. A sheltered life can be a daring life as well. For all serious daring starts from within. [...] Good writing is supposed to evoke sensation in the reader - not the fact that it is raining, but the feeling of being rained upon" (paragraph 9).

4.

The definition of "abstract" that most closely matches the meaning of the word in the text is "a theoretical concern or consideration about something." In the essay, Didion writes about her own abstract ideas about writing and the role of the writer in society, rather than concrete details of her life or specific events.

Explanation: Didion's essay is largely concerned with her own reflections on the writing process and her own reasons for writing. She is not writing about specific events or concrete details, but rather about abstract ideas and concepts related to writing. Therefore, the definition of "abstract" as a "theoretical concern or consideration about something" is the most applicable.

5.

In paragraph 20, "coalesce" means to come together or merge. Didion is using the word to describe how her ideas and thoughts about writing come together to form a cohesive whole. She believes that writing is not just about individual sentences or paragraphs, but about creating a unified whole out of disparate parts.

Explanation: Didion writes that her writing process involves taking individual sentences and then "trying to make them coalesce, to give them some shape and order" (paragraph 20). By using the word "coalesce," she is describing the process of bringing together individual elements to create a cohesive whole.

Answer:

Please, see below 
letter is same that I mentioned in your last query. 
Hope this help you.

Step-by-step explanation:

Addrees:

Hello Sir/Madam
I'm writing to you in response to the claim that cars are unsafe, stinky, dirty, and noisy. They ought to be prohibited from all town and city centres so that people can cycle and walk in peace. I want to make it clear that this isn't always the case, and I'll explain why in this letter.

First of all, there are many measures in place to make sure that cars are not "downright dangerous"; for instance, speed limits, traffic lights, and zebra crossings; these make sure that nobody is at risk of being hurt by a car; they are all very important and give you the same sense of security as being at home. Instead of outlawing vehicles, our society could band together to impose more regulation on them by increasing the number of zebra crossings and traffic lights.

Second, drivers must pass a driving test to demonstrate that they are qualified to own and operate a vehicle and that they are knowledgeable about how to prevent endangering others or behaving dangerously around them. This is done to ensure that cars are not unsafe.

Another thing I want to point out is that people who live far away and work in town or city centres need a car because it's the only way they can get to their place of employment directly. It would be too inconvenient for them to cycle or walk, and people with disabilities can't cycle or walk, so they will need to use a car as a means of transportation. According to a recent survey, 85% of individuals indicated they couldn't get to work without a car, therefore banning cars would result in people losing their employment, but also in those with disabilities becoming even more disadvantaged than they already are. 

How would you feel if you couldn't walk or ride a bike to work due to a disability and lost your job as a result?
There are cars that have been produced recently that are eco-friendly, ensuring that they are not "smelly, noisy, or dirty," as described in your remark, which is another reason why I disagree with it.
These vehicles are excellent since they make people feel more at home and don't contribute to pollution.

I appreciate you reading my letter, and I hope to hear from you soon.

my heartfelt thanks
