1)the gemara has a shailah about dates that fall on Shabbos: are they muktzah because thy were unfit for human consumption when Shabbos started, or are they permitted because they were edible for the ravens, so they aren’t muktzah. We bring a proof from a cow that dies on Shabbos, that was edible for humans before Shabbos and is edible for dogs now. My Question is that the two cases are non similar, because not only were the dates prepared for ravens before Shabbos, they are still edible for ravens now.
2) the gemara says that the inhabitant of Yericho were wrong for giving peah on vegatables, because no maser was taken off. My question is, what difference does it make if its mechuyav in peah or not, in both cases he is mafkir it when he makes it peah, and its patur from maser.
3)Your freezer breaks on Friday night. Inside are frozen lamb chops, french roast, chicken cutlets, hot dogs, salmon steaks, and a $200 cut of Kobe Whag-Yu steak. What can be moved to a working freezer, if anything? Would you act differently if the above scenario occurred on Shabbos afternoon?
