1.	Dry sand does not have the strength for what functions?(a) To withstand corrosion forces(b) To withstand pressure of molten metal(c) To be able to retain its shape(d) To be able to retain the hardenability
Answer» The correct choice is (d) To be able to retain the hardenability For explanation I would say: Dry sand has its strength for various purposes like, to withstand a pressure of molten metal, to withstand corrosion forces and to be able to retain its shape. But it does not have it for being able to retain the hardenability.
