Answer 1

Answer:

The sieve used to separate sand particles and rice seeds should be such that it passes sand through its holes but the rice seeds cannot pass through them. The size of holes should be greater than the size of sand particles but less than the size of rice seeds

Answer 2

The aggregate should be oven-dried at high temperature before sieving to prevent lump formation of the fine particles due to moisture content, which might clog the fine sieve holes.
