Hello Mary,
I'm not really sure what you mean. When I was teaching, we used to talk
about 'yes-no' questions:
Are you English?
Does Robert live in Syria?
Have you brushed your teeth today?
But the only other real formal 'question' category I knew of was
'question word' questions:
Where are you from?
Where does Robert live?
When did you last brush your teeth?
For me, a 'true-false' question is just an exercise style (along with
fill-in-the-blanks, match the answers, unscramble the letters, extended
comprehension, etc.). So if you asked me the difference between a
'yes-no' question and a 'true-false' question, I'd assume you were
talking about a type of exercise:
1) Answer the questions:
Does Robert live in Syria?
is an example of a yes-no exercise.
2) Mark the statements true (T) or false (F):
Robert lives in Syria ___
is an example of a true-false exercise.
