Riddle
Rule: Circle=Yellow. Cards: C, S, Y, R. Check?
Choose an answer
A.Square and Yellow
B.Only Circle
C.All four
D.Circle and Red
Hint: It's a 3-word phrase with 12 letters, starting with "C".
Answer
Circle and Red
Why this is the answer
You check the Circle (to see if back is Yellow) and the Red card (to see if front is a Circle, which would break the rule). Yellow and Square can't invalidate the rule.
