The FISH and PIRATES

When I saw both of these question in the exam today,
I was like what the ????
The only thing I know about fish and pirates,
is that both can be found in the open sea.
Did the lecturer really taught it? (no recollection whatsoever )
Could not find it in the notes or Khay Shi's (nickname "copywrite")
Other then the FISH and PIRATES,
one can also find my B in the sea now.
