Rewriting, editing and giving selling meaning to a finished article

There's a ready-made "raw" article. The essence of the work is as follows:
1. Rewright of the introductory part of the article, 1658 nomenclature / b.p.;
2. Rework and replace frequently repeated words and phrases with synonyms;
3. To give the text greater semantic / logical coherence;
4. The article is being processed under the “selling” (especially the last paragraph);
5. Elimination of spelling, syntactic and mechanical errors. General stylistic, artistic processing of the text.
6. Pick up some headlines.
