As I indicated in my mod message reply, you should provide full attribution per the help center guidance on referencing material by others. Your post did not include a link to the original source. Posting a link in a comment is not proper attribution. Specifically, attribution should clearly indicate to the reader which parts are taken from another source and which parts are your own work (in case of modifying the source material).
In your case, you copied just short of entire sentences verbatim from Wikipedia while changing minor bits. As such, the plagiarism could not be resolved by adding a link to Wikipedia and including quote markup. As is standard policy, posts containing plagiarism are deleted with a message asking the author to correct the plagiarism and flag it for undeletion.
