Question 12

ProductSpec_2

Size	Color	Price
S	black	55.9
M	red	70
L	black	55.9

ProductSpec_2 is different from ProductSpec given in Question 1 because the price of the third row is 55.9.

If Size is defined to be the primary key of ProductSpec_2, then it is a table of (choose only the best answer)

1NF

2NF

3NF

neither 2NF nor 3NF

Question 13

ProductSpec_2 given in Question 12

can be normalized to Table1(Size, Color) and Table2(Color, Price)

can be normalized to Table1(Size, Color) and Table2(Size, Price)

can be normalized to Table1(Size, Price) and Table2(Color, Price)

is already normalized to 3NF and cannot be normalized further.
