We ' ve all heard it before , and I ' m sure some of the other 2D 's felt a little bit of pride , but some of the new students got kind of hushed and worried looking . The teacher went about it in a very good way though . Apparently , Kota and I had Ed during his first semester he ever taught . We were n't aware of it then , because he was excellent .
According to the above context, choose the best option to answer the following question.
Question: Why are Kota and the speaker surprised that it had been Ed 's first semester ever teaching ?
Options:
- He was a great teacher and they were sure that he had been doing it for some time
 - Ed was the one that got them their jobs so they do n't understand how this can be the case
 - Ed had been the grandson of the former principal so they assumed he had been around longer
 - Ed seems far too old to have only just started teaching , and they are in disbelief
