وحدات منهج الصف الثالث الثانوي الجديد (بالتتابع)

[ibrahimsafi]

I'd like Sir to ask you a question
Is "During" followed by a gerund or a noun?
In a great number of external books, they mention that during can by followed either by a gerund or a noun
But some teachers say that " During" can only be followed by a noun
i have investigated the matter and looked it up in over 80 english references (grammar books, usage books and dictionaries using electronic search) i haven't encountered during followed by a gerund
I seek your opinion, Sir
