actually a Model Instance, a ViewModel instance and a View 
instance. Or even a set of a Model-type instances, a ViewModel-type
instances and a View-type instances.
The issues I'd expect to be found in the "essay"'s text:
- improper use of indefinite and definite articles, 
- improper use of the Present or Continuous Tenses, or
just improper use of Grammatical tenses in
general,
- words'/sentences' repetitions, 
- poor command English or tongue-tied English,
- punctuation,
- wrong usage of prepositions and postpositions;
- wrong usage of verbs, words combinations,
- writing style in general,
- mistypings,
