She doesn't want him to know
Answer:
C.
Explanation:
I usually get told this is incorrect from the point of view of someone else who has been corrected multiple times in the past. Understandably, if Tammy doesn't like you, you wouldn't tell her.
But, in a perfect world, this is [ideally and probably] the best way. Letting Tammy know "hey, this is how to improve" is better than humiliating her in front of her friends and the teacher and ultimately bringing down her confidence. Direct correction might work better because then she will see her mistakes and be told how to fix them for her future reference.
Remember: Writing is thinking. Writing is literally just translating the words you're thinking into words on a page/computer or other media.
If she [Tammy] is offended, talking to the teacher may be the best way so the teacher can handle it.
In the excerpt from chapter 6 of Animal Farm, humans, even though they are sure that the windmill won't ever be successful, have a sense of recognition and respect for what the animals have done, for their hard work and persistence to manage their own affairs, which granted them independence. This recognition of effort regardless of what the results can be is something natural of humans, and that is why the answer is D. They value efficiency and accomplishment.
