Answer:
Good morning/evening ladies and gentlemen today I am here to talk about the topic people are never satisfied with what they have . They always want more . For example if I stop right now the teacher won't give me marks since she wants me to say more about the topic :-) We don't want that now soo let me continue people are never satisfied with what they have they are greedy and sometimes this greed leads to disasters .But for some others a bit greed can help them be successful.This people are very kind and they know how hard life is so they try to make it a bit easier for other people. This will lead them to even more success and in turn more people will be helped by them . But since people are greedy at one point or the other they will stop helping society.They forget where they came from and starts thinking only about themselves.This is why there are people around the world who don't get food ,water and other basic necessities.I am not telling that the rich are obliged to help the poor but the people who are really in need for help like orphans.But they don't do this because of greed.If it wasn't for greed many people would have had a better life but for many life wouldn't be so kind.So greed is a necessary evil like friction.As you need to apply lubricants to prevent friction from ruining things . You need to learn to control greed but many people don't do so because they don't want others to be as great as them, because of greed. This leads to the fact people are never satisfied with what they have and never will be .
Thank you and have a nice day.

The harmonic frequency refers to the resonant frequency that is an integral multiple of the fundamental frequency, harmonics are usually simple sinusoidal oscillation at a single frequency. where as Resonance frequency are frequencies that are not necessarily sinosudal or integral multiple of fundamental frequency and it may have complex oscillations made up of multiple harmonics ~
It's like if you play a piano with a single key, it will show harmonic frequency, but if you use multiple keys at a time it may show Resonance.
"Angela's Ashes" is a controversial book and one that had an even more controversial repercussion helped him to shape people's intense reaction to this book.
This book recounts the memories of its author, McCourt, living in a backward region, with neglectful parents, precocious sexuality, hopelessness, death and poor quality of life. In addition, McCourt expresses depressing and derogatory thoughts within controversial memories and with a strong psychological content.
Because it is a book with strong and impactful themes, many people did not like the book because they believe that the author exaggerates and glamorizes the suffering and broken personal relationships. Other people, however, liked the book because it portrays a reality that many people go through and that the governments and people favored in society do not care.
Many events narrated in the book were denied by witnesses and people who lived with McCourt, which favored the negative reception that the book received. McCourt himself claims that he has modified some situations to make the narrative more fluid and engaging.
