A: Comparison with other students' writing.

Explanation:

Writing is a very personal exercise that can rightly be evaluated based on certain coordinates like grammar and syntax, coherence, congruity, use of sources, arguments and counter arguments, and content in general. These are all good peer review coordinates, but comparing somebody´s writing with others´ writing is not only a negative possibility, but it can actually harm the style and contents of somebody´s writing. Peer reviews should focus in on the writing in question, objectively, independently of other people´s writing.  

1) technical language (writen technical volcabulary)

2) ordinary langauge

3) literary language (because it's text with a rich, descriptive vocabulary)

4) scientific texts (includes texts such as medical reports, legal texts, academic journals, etc)

5) informational texts (texts that are used to convey information to readers, such as technical guides, costumer guides, textbooks)

6) poetic texts. because they are essays, short stories, poems, etc.

the words “strangest” and “unusual” suggest that the narrator is about to tell the story of an odd or puzzling group of people.
