2. ... a basket with a stone inside it on Shabbos.
(b) We might have thought that it is forbidden - because the stone is Muktah.
(c) The latter case is forbidden if there is no fruit in the basket - because the basket is a Basis le'Davar ha'Asur (a base for a Muktzah article).
(d) The Heter will not apply if the fruit in the basket comprises nuts or almonds - because one is then obligated to tip them out of the basket ...
(e) ... and the reason that it is permitted if it comprises strawberries and grapes is based on the fact that will get spoilt if one tips them out.
