Anchor: If WTP for reductions in mortality risk is linear in risk reduction, then a WTP of $50 for a reduction of 1/100,000 implies a WTP of $500 for a risk reduction of 1/10,000 (which is ten times the risk reduction valued in the study).
Entailed: The WTP for reducing mortality risk might be linear.
Contradiction: There is no way that the WTP for reducing mortality risk could be linear.
Contradiction: Both of us have to leave the car right away.
Contradiction: There are two children in this picture, and they are outside.
Contradiction: No money is going into training. 
Contradiction: The Fourth Railway Bridge was a big achievement in engineering.
