Brand-new feature value in the target

Question (3 marks):

Four shapes are shown:

• Striped pentagon = WP
• Dotted pentagon = XP
• Striped hexagon = WH
• Dotted hexagon = XH

The target shape is a black (solid) pentagon — a shading that does not appear in the examples. Which of the following is most likely the correct code?

A) WP B) XP C) YP D) WH E) XH

Mark scheme (3 marks):

• 1 mark: recognising the 1st letter encodes shading and W/X are already taken by striped/dotted.
• 1 mark: recognising the 2nd letter must still be P (pentagon).
• 1 mark: choosing C) YP — a new letter (Y) for the new shading value (black), keeping the pentagon letter unchanged.
