Yes, all of the changes made in the new sentences are correct.
3. (Pronoun Agreement Error) The original sentence had a pronoun agreement error because the pronoun "their" was referring to "every student," which is a singular subject. In the new sentence, the pronoun "they" correctly agrees with the plural subject "every student."
5. (Subject-Verb Agreement) The original sentence had a subject-verb agreement error because the singular noun "container" was paired with the plural verb "are." In the new sentence, the plural subject "toxic chemicals" is paired with the appropriate plural verb "are."
10. (Misplaced Modifier Error) The original sentence had a misplaced modifier error because the phrase "wearing a cloak and top hat" was placed after "audience members," suggesting that the audience members were the ones wearing the cloak and top hat. In the new sentence, the modifier "who was wearing the cloak and top hat" is correctly placed next to "the magician," clarifying that the magician is the one wearing the cloak and top hat.
