"I immediately open the book."

Translation: Tôi ngay lập tức mở cuốn sách.

[ThuyVyTran4]

Isn't the correct sentence given grammatically incorrect? 'Tôi ngay lập tức mở cuốn sách', shouldn't it be 'Tôi mở cuốn sách ngay lập tức' instead?

[Huy_Ngo]

Both are okay. Place of adverbs in Vietnamese is not as strict as in English.

I agree that the second arrangement does sound better and there should be multiple accepted answers as long as the sentence conveys the same meaning.
