Translation:Are you studying?
study could more accurately be translated as "tanulmányoz" when describig what scientists do, like "studying an animal in its natural habitat" for example. When you just learn something that someone else came up with, it's always "tanul", so we don't "tanulmányozunk" for an exam.
Is 'L' pronounced in the letter combination 'lsz'?
I am not sure if it's pronounced or not...
Yes. It is just a combination that suppresses the "L" a little bit. Like in "false".
It sounds like the emphasis is on the second syllable in the audio. Is that because it's a question?
