Turkish Tv Series

According to a rumor, some speech therapists give the line spoken by Bihter Ziyagil in the TV series Aşk-ı Memnu

“Of course, the children entrusted to you by their mothers…”

as a tongue-twister for pronunciation practice.

When I saw that scene, a famous long Turkish word immediately came to my mind:

“muvaffakiyetsizleştiremediklerimizdenmişsinizcesine.”

Then I started wondering:

If this sentence had appeared in a Turkish university entrance exam (TYT) reading paragraph before the show became popular, how many people would have actually answered the question correctly?
