Every teacher will experience this situation a hundred times. A student was, for one reason or another, not able to complete an assignment and the teacher is placed in the position of deciding what to do. Do we extend a deadline for anyone or everyone or based on each circumstance or do we hold firm to our deadline? As a teacher, it's important to show the students that we are the ones in charge and that in the real world, you simply can't not get something done on time. But as teachers we also have a certain amount of compassion and understanding. In this situation, I believe that the teacher did the appropriate thing and the student will have to do the assignment with the little information he has.
