In my opinion Ms. Hoda

الأجابة يجب أن تكون Expression وهذا تعريف الكلمتين لنعرف الفرق.
expression= things that people say, write or do in order to show their feelings, opinions and ideas
Exposition= 1)a presentation and explanation, especially of difficult ideas, a theory, plan,etc
e.g. A clear and detailed exposition of their legal position.
Exposition=2)an event at which people , businesses,etc. show and sell their goods; a trade fair
اللبس ربما قد ينشأ لأن كلمة Exposition فى المنهج هذا رأى ولك تحياتى.
