Here’s a grammatically corrected version of the sentence:
"After Gloria finished her test and turned it in, she took out her science book and notes, which were not allowed during the test, and observed that she did well."
Explanation of Changes:
-
"After Gloria finished her test and turned them in" to "After Gloria finished her test and turned it in":
- The word "them" was changed to "it" to correct the pronoun usage. "Test" is singular, so the corresponding pronoun should also be singular.
-
Added a comma after "turned it in":
- A comma is needed to separate the introductory clause from the main clause that follows.
-
Inserted a comma before "which were not allowed during the test":
- This comma indicates that the clause "which were not allowed during the test" is non-restrictive. It provides additional information but is not essential to the meaning of the sentence.
-
Changed "did good" to "did well":
- "Good" is an adjective and should not be used here. "Well" is an adverb and is the correct word to use when describing how she performed.
These changes enhance the clarity and grammatical correctness of the sentence.
