2) Suppose referee adopts neutral scoring with Q=4 and asks the same question with a probability P_{S}=0.25. This reduces the average loss rate for their partners for the following reason: Consider a probability space with

- a) 4 equally probable events: On three they are given different questions, winning twice but losing once. On the fourth event they are given the same answer and neither gain nor lose a point.
- b) 4 equally probable events: On three they are given different questions, winning once but losing twice. On the fourth event they are given the same answer and lose a point.

- a) No unique answer exists because two variables are involved (temperature and volume).
- b) The hotter object has a greater energy density.
- c) The larger object has a greater energy density.
