Mouse R eat pellets by testing time.
This sentence doesn't make sense.
|Mouse R had eaten her pellets by testing time.|

Your subject and verb should agree. If your subject is singular, so should your verb. A plural noun calls for a plural verb.

|The hardest task on my list was to master cryotherapy. task is my noun [singular], was is my verb [singular]|
|Dangling Modifiers||This happens when words that are being described are not placed close together. This makes it sound like the sentence isn't actually about what it is. The modified words should be IN the sentence.||
While perusing the project proposal, it is difficult to read.The proposal isn't reading itself, we need to talk about WHO is having the difficulty reading.
|While perusing the project proposal, I find it difficult to read.|
|Faulty Parallelism||If you're stringing a list of things together, the verb should make sense for ALL the words in the list. If not, use a different verb for each list item. Make sure the verb ends in the same tense||While technically he could win fame and fortune, the reference here is to get or increase fame and fortune. This isn't parallel to winning.||John hoped the project would win the contract, garner fame, and increase his fortune.|
|Unclear pronoun reference||The pronoun must clearly refer to the noun. Be careful when using the pronouns it, they, that, these, those, and which||
As a brilliant scientist, that allows him access to the CERN Supercollider.He gets access because of his brilliance, but we are talking about HIM as a person. Use the personal pronoun whenever possible
|Since he is a brilliant scientist, he is allowed access to the CERN Supercollider.|
|Pronoun agreement||If your subject, or the noun you're referring to is singular, you should use a singular pronoun. If the subject or referring noun is plural, use the plural pronoun.||

|When a student requests an extension, he or she demonstrates poor time management skills.|
|Omitted commas||Commas should be used to set off non-essential parts of a sentence, and to indicate relationships between ideas and parts of the sentence||
Although a respected teacher Dr. J made some unethical decisions.The point of our sentence is that the dr. made unethical decisions. The introductory part is not essential to the point, and therefore should be set off with commas.
|Although a respected teacher, Dr. J made some unethical decisions.|
|Too many commas||It's possible to go too far with including commas. Use commas only to set off non-essential part of a sentence, indicate relationships between ideas and parts. Extra commas make your writing harder to read.||It is impossible, to write a paper, that will meet the journal's requirements.||It is impossible to write a paper that will meet the journal's requirements|
|Comma splice||This occurs when a comma is used to join two complete clauses - that is to say, one sentence that could (and should) function as two. Use a semi-colon or period to link the sentences, or rewrite the sentence.||Mike took the specimen to the lab, Susan returned the subject to its cage.||Mike took the specimen to the lab. Susan returned the subject to its cage.|

Rachel borrowed they're microscope.
they're [they are]their indicates possessive
|Rachel borrowed their microscope.|
