Explain the following quote and how it relates to democracy “government that begin by burning books end by burning people”

Answers

Answer:

This is because the Nazis which ruled Germany did this .They first started with the burning of the books which contained the rich culture and tenets of the country under the guise of cleansing the country.

They then started burning the people who were mostly Jews during the holocaust in which Adolph Hitler was in charge. This explains the meaning of the burning of the books and a big emphasis is placed to avoid a reoccurrence due to the bitter experiences and memories it left on the people.

Can you help me write an essay on #BlackLivesMatter based on the manifestations?

Answers

                                    Black Lives Matter

  Black lives matter is a political and social movement originating among African Americans, emphasizing basic human rights and equality. Black lives matter started in 2013 when people started using the hashtag #BlackLivesMatter on social media after the acquittal of George Zimmerman in the shooting death of African-American teen Trayvon Martin in February 2012 because black people weren't being treated the same. It started because Black people were being treated differently and right now everyone should be treated the same. The year is 2020 and people still act like it's the 1900s!

 The purpose of Black Lives Matter is to spread awareness and to make a change for equality. The sad thing is that Black Lives Matter doesn't affect any social class, age, etc, it only affects your skin color which is very sad because no one can control their skin color, so it affects African Americans and people who are dark skin. It isn't only happening in America, protests are happening all over the world like the UK, Germany, Italy, New Zealand, Canada, Palestine, Syria, and other places, but it's mostly happening in America. For things to change powerful people need to help.

 Protests are happening for Black Lives Matter and I think that what the people are doing is good because they are protesting for equality, but some people are taking advantage of the protests and use it to destroy things which makes people think that all these protests are useless, and the powerful people like lawyers, police officers, the president, the government. etc. aren't doing much.

 On May 25th, 2020, George Floyd, a 46-year-old black man, died in Minneapolis, Minnesota after Derek Chauvin, a white police officer and 3 others, knelt on his neck for almost nine minutes while he was handcuffed face down in the street. Many people were watching but none of them did anything to help George Floyd because they were not powerful enough. This all happened because George Floyd was suspected of giving a counterfeit $20 bill. This makes me very sad because George Floyd did nothing to deserve this and black people are being treated like this every day just for having a dark skin color which is something they can't control. Black people are given stereotypes, if you're black you are a “thief”, a “killer” and many more racist stereotypes that have nothing to do with the color of someone's skin. Black people are being treated brutally and are being killed by white people who think they are the most superior race.

George Floyd, Sean Reed, Ahmaud Arbery, Eric Garner, Ariane McCree, Steven Demarco Taylor, Terrance Franklin,David McAtee, Natosha “Tony'' McDade,Yassin Mohamed, Kwame “KK'' Jones, Trayvon Martin, Tamir Rice, these are all names of unarmed blacks who were shot and killed by white supremacists, and there's even more but they are too many to name.

 Dylann Roof Kills 9 and he is arrested peacefully, Patrick Crusis kills 28 and he is also arrested peacefully, but Eric Garner who Killed 0 people allegedly sold illegal cigarettes choked to death while stating “I can’t breathe”.George Floyd Killed 0 people, allegedly wrote a bad check murdered on camera.

The phrase ”All Lives Matter '' is a phrase used in response to “Black Lives Matter” but it does not represent the same thing. People say it and it is wrong, all lives don't matter until black lives do! You can't just say “all lives matter '' when it's black lives that are suffering. ‘Black lives matter’ doesn’t mean other lives don’t matter, it's just that right now black lives are the ones that are suffering the most and we should try our best to help them.

Explanation:

On March 4, 2008, John McCain became the Republican presumptive presidential nominee when he obtained the 1,191 delegates necessary to receive the party's nomination. Mike Huckabee announced his withdrawal from the race later in the evening. McCain's last remaining competitor in the race, Ron Paul, withdrew on June 12, 2008.

In 2008, he faced off against Democratic nominee Barack Obama in a closely contested election that ultimately resulted in an Obama victory.

Explanation:

Read the passage about energy use in Dallas, Texas, from the US Department of Energy. During the past five decades, Dallas’s population has nearly doubled—growing from 679,000 in 1960 to more than 1.2 million people today. To support this rapid growth, develop a sustainable community and reduce Dallas’ impact on the electrical grid, the city created the Green Dallas Initiative with support from the Energy Department’s Energy Efficiency and Conservation Block Grant (EECBG) Program. Using some of its EECBG funds, Dallas focused on improving the energy efficiency of 248 city-owned buildings, totaling 3.3 million square feet. Following energy audits, the city made energy efficiency improvements that included upgrading to energy-efficient indoor lighting at more than 150 buildings and installing digital HVAC controls—technology that allows the city to monitor energy use and continuously adjust the systems to increase efficiencies and reduce energy consumption—in 100 city-owned facilities.
Which best explains why Dallas has needed to find ways to reduce energy consumption?
A.Dallas’s population has grown as people have moved from the Rust Belt to the Sun Belt.
B.Dallas has run out of ways to create renewable energy and must use new sources.
C.Dallas has lost population and must reduce energy costs due to lost tax revenues.
D.Dallas’s federal funding is tied to a requirement that it reduce energy use by 50 percent.

Answers

Answer:

A.Dallas’s population has grown as people have moved from the Rust Belt to the Sun Belt.

Explanation:

Dallas is one of the fastest-growing cities in the United States, and one of the main reasons is that many people have moved from the lagging economies of the Rust Belt, to the more dynamic economic of Dallas, which is located in the Sun Belt.

Because of this growth in population size, and also because Dallas has a very hot climate during most of the year, it has become necessary to find ways to improve the efficiency of energy consumption in the city, like the excerpt in the question explains.
