I do not agree with the statement "the school ‘s current policy should be changed to allow students to carry them".
Students should use cell phones for :
i. additional learning outside their school curriculum,
ii. developing skills via watching tutorials on online etc,
iii. developing research skills by finding relevant information.
However, hardly few students use cell phones appropriately.The major chunk of students use mobiles in wrong ways, like, watching bad content, playing online games, passing time on social media. All such things decrease the productivity of the students & fill their mind with lot of un-necessary content.
Hence, I strongly feel, cell-phones should be banned in school. Also, their usage should be restricted at homes too.
I’m presuming the last one is supposed to be bias, but that’s the one that has a negative connotation to it.
In George Orwell's book "Animal Farm", Napoleon is represented as a scary and intimidating pig, who controls the other animals through fear and propaganda. In the book, the first descriptions of him were "fierce-looking" boar "with a reputation for getting his own way." as well. Napoleon was also a metaphor for Joseph Stalin, so the animals on Animal Farm see Napoleon the same way people saw Stalin. For example, both Stalin and Napoleon surrounded themselves with guards, they were cruel, and wanted power and were willing to use any means necessary to get it.
