There are also those questions that are just strange.
I had a question which asked for the function of the corpuscles in HPL. The answers all seemed plausible as they were all functions of different things in the body. Is there a need to include such rare/ seldom used vocabulary when so many who sit the exams are not native/ fluent English speakers? I thought we were studying to fly a plane and not medicine.
I was very thankful the CAA I did my exams at had some pretty hefty dictionaries with some of the ludicrous vocabulary used. You had to be careful though as you'd break your foot if you dropped one of them.
It's definition 2a if you don't know -
