The given sentence is: "Practically, any parts of banana tree is useful to man." The underlined phrase "any parts" indicates a potential error in the sentence, and we must determine if it is grammatically correct or if a substitute option should be used.
Let's evaluate the options:
From the above analysis, option 3, "every part," is the grammatically correct choice. It aligns with singular usage, fits the context of the sentence, and agrees with the subsequent verb "is." Therefore, the corrected sentence is: "Practically, every part of banana tree is useful to man."
Identify the part of the sentence that contains an error:
"Neither the manager nor the employees ___ willing to accept the new policy."
