[Avodah] gemara narrative

[Rich, Joel via Avodah]

When you are learning gemara and you come to a give and take where
the hava amina seems strange (e.g. maakot 14a where the gemaras first
assumes the rabbanan learn a din from lchaleik yatzah and ask where
does R' Yitzchak learn it from. Gemara answers from a different pasuk
and then asks why don't the rabbanan learn it from there. the answer
is ein haci nami?! -- so why record the whole misattribution of reason,
and how did they know/not know)
