Please answer the following question: I know that the answer to the question "Which effect of water is unique to wood, at least in this context?" is in "The general effect of the water content upon the wood substance is to render it softer and more pliable. A similar effect of common observation is in the softening action of water on rawhide, paper, or cloth. Within certain limits, the greater the water content, the greater its softening effect.". Can you tell me what it is?
A:
pliable
