Let's evaluate each sentence one by one:
A: "the theme of the points were complex."
Incorrect. The subject "the theme" is singular, so it should be "the theme of the points was complex."
B: "the friend who I studied with helped me a lot."
Correct. This sentence is grammatically correct, although it's more common to say "the friend with whom I studied" for formal contexts.
C: "Summer's favorite childhood books were good night moon, by Margaret wise brown, the little house, by Virginia Lee burton, I am matilda, by Ronald dahl."
Incorrect. There are several issues:
- There should be a comma before "by" in each book title.
- The titles should be capitalized: "Goodnight Moon," "The Little House," "I Am Matilda."
- The sentence should end with a period.
D: "within the box was an old, elegant, beautiful necklace, which Allison immediately adored."
Correct. The sentence is grammatically correct, but there should be a capitalization at the start: "Within the box..."
E: "he my English class was locating sources for essays."
Incorrect. This sentence is unclear due to "he." It should probably start with "In my English class..." to make sense.
So, to summarize:
- A: Incorrect
- B: Correct
- C: Incorrect
- D: Correct (with capitalization)
- E: Incorrect
