hi all

thanx for the replies

but i'm not sure if they were the right answers
what i asked was the question to "he's the fourth president"
where it was sressing on the "fourth".

so the question is supposed to ask about his position in the list of presidents.

making it clear, yu know he's president but yu don't know where he stands
in the list of presidents. In that case i don't think yur answers were correct.

in the same way, yu're watching a movie of yur favourite director and yu
want to know where it comes in the list of his entire movies.

so to get an answer "its his fourth movie", where it stresses on "fourth"
what simple question should you be asking?
yu can't do it with "is his fourth movie?" when yu don't know if its his fourth or fifth!!

so i'm looking for the questions which points at getting the positions.

i'll repeat the questions.

"he's the fourth president" or "it's his fourth movie?'
