**Question 3**

You are not requested to come up with a real life example, but rather with a schema and a set of tuples - e.g., (a1, b1, c1), (a2, b2, c2) - that violates the "rule".

**Question 5**

You **cannot** assume item# is unique; you also **cannot **assume there
is only one item# with the same color or size.

**Question 6**

Note that the original algorithm to compute the new set of FDs is described in the book, page 147.
