Hi again

a couple of days have passed and I´m bach with some questions.
1. Explain the difference between long and short passive by refering to the following sentence.
The letter to my friend get written by me anyway.
I would say that the long passive has been used because the sentence has an agent and it has a "by phrase". Oh dear my explanation sound really dull... what do you think? is it a long passive and do you have a better explanation?
2. Which of the given nouns are abstract and/or common?
teacher
New Zealand

e) I´ve just got a postcard from a woman whom I met on holiday last year.
f) The idea that Polly is John Hardley´s daughter surprised all in the room.

very tired. Unforunately. eating has been her
obvious weakness for several years. They were on duty
