TASK 5: THE INVITED PROFESSOR IS NOT ABLE TO COME

Sam is in charge of the classic movie club, and he is entangled in a dilemma.
He is able to invite a famous professor make a introduction before the movie time, but the professor wasn’t able to come because of some family emergency all of a sudden. He can have two options to solve this problem. The first one is to reschedule the movie time. But he is afraid that most of the students may not notice the emergent announcement and still come to the club on regular time. The second one is to introduce the movie by himself. He has enough materials to do the job, yet he is not able to handle the Q & A part because he dosen’t have much knowledge compared to the professor.
