Why do the Rabbanan say that he is Patur?

(b) What does Rebbi Yehudah say about that?

(c) The Gemara initially gave the reason of the Tana Kama as being that he might come to eat it whilst it is still alive.
On what grounds does the Gemara refute that contention?

(d) Our Mishnah maintains that one does not keep a forbidden creature for a child to play with.
Does this clash with the opinion which holds that one is not obligated to separate a child from a child who is eating Neveilah?

Hadran Alach 'Amar Rebbi Akiva'!

Perek ha'Matzni'a
11)
(a) We have already learned that someone who stores away less than a Shiur of any commodity, will be Chayav if *he* subsequently carries it out. If he then changes his mind, and decides to revert to its original use, will he be Chayav for carrying it back inside?

(b) Why does the Tana need to tell us the case of someone who first stored away the commodity and then carried it out - when he could have simply stated a case where he simply carried out a minute amount specifically for sowing, as a sample or for a cure - even without having stored it first?
