In the previous shiur, we understood the primary difficulty for the amoraim in the gemara with the drash that was used in the beraita with which the gemara began.
In this shiur, the amoraim will refine the problem and show us exactly for whom (i.e. which amoraic position regarding the scope of the mitzvah of נטע רבעי) this problem exists. We will begin with the words הניחא למאן דתני, about half way down the page on Berachot 35a.
