How to make a gingham christmas wreath<br>Buy a medium-sized wreath form from the craft store. They are available in wicker, metal or plastic. Choose wicker or metal wreath form that is approximately 1 foot (0.30 m) (30. 5 cm) in diameter.
A paper wreath is definitely better than a wicker or metal wreath. 
Paper is way too flimsy to be considered better material than wicker or metal, and the context specifically states to select a wicker or metal wreath - it would have mentioned paper as an option if it was viable, therefore, based on basic logical analysis, my statement is definitely correct. I think the system had difficulty because it does not understand paper is not sturdy enough to support ornaments or withstand weather conditions, especially in comparison to wicker or metal.
