Hi Teachers,

long time no see, hope you are all fine.

I have got a question unsolved for a long time, it is about using "OUT OF" ..

ex.1
your score is 7 out of 10

ex.2
keep bugs out of the house

ex.3
out of respect for someone

ex.4
out of the question

it is like saying A out of B, sometimes means A is part of B, sometimes means A is separated from B ,hope you see what I mean

thank you in advance
