Question

Which of the following can be deduced from (I), (II) and (VI)?

• A. Black is on the top
• B. Blue is on the top
• C. Brown is on the top
• D. Brown is opposite to black

Hint:

If \(X\) is opposite \(Y\) and one of them is fixed as bottom/top, the other is instantly fixed as top/bottom.

Answer 1

The Correct Option is A

Step 1: Use the opposite-pair fact.
(II) Red is opposite Black.
Step 2: Use the given fixed face.
(VI) Red is the bottom face \(\Rightarrow\) the face opposite the bottom (i.e., the top) is Black.
Step 3: Conclude.
\(\boxed{\text{Black is on the top}}\).
