I think there's a mistake in the grammar. I will try guessing what the sentence is.
1st guess: Qui est-ce qu'elle est? ----> Who is she?
2nd guess: Qu'est-ce qu'elle est jolie! -----> How pretty she is !
3rd guess: Qui ect-ce qui est jolie? -------> Who is pretty?
"quelle jolie femme" means "what pretty woman? / what a pretty woman!" in French.
quelle jolie famille
"Sur quelle rue" in French translates to "which street" in English.
à quelle heure as-tu faim means 'at what time are you hungry' in English.
Which season is it
"C'est jolie" - "It's beautiful"
Une jolie fille means 'a pretty girl' in English.
'mais quelle est cette ...' means but what is this (thing) / who is this (person).
It means- What time is it?
Pretty (and it's feminine)
"Il est quelle heure" means "What time is it?" in French.
It is spelled Jolie and it means pretty
