"Bosphorus" - what is it?

Great question and choices! Shakespeare- Prospero Chemistry- phosphorus, or 83 is bismuth don't know what temple was meant.

TestyAlien3443, It's Bismuth for Chemistry one and Phosphorus is P

I thought the name was Bosporus.....

Thie explanation is inaccurate- there is a small sea between the Black Sea and the Aegean Sea, Marmara, so called because it tends to be calm, and the flat surface is liked to marble, or Marmara

In my language it is written as Bosporus without an "h". So I took it for a trick question 😩
