Thank you, Writeacher.
Here are some other sentences I need you to check.
1) Your paragraphs show a poor knowledge of grammar as well as of word accuracy (correctness, property) and cohesion.
2)The choice of tenses is often wrong since you mixed present and past in the same sentence.
3)Your account (description) of historical events is incomplete and occasionally wrong.
4) Finally, you failed to include sentence connectors to link your ideas together.
In 1, I'd refer to word accuracy as correct word choice.
In 2, I'd use "inconsistent" (more specific than "wrong").
Other than that, the sentences are fine.
