There are two distinct proposals, a and b, being debated in washington. the congress likes proposal a, and the president likes proposal b. the proposals are not mutually exclusive; either or both or neither may become law. thus there are four possible outcomes, and the rankings of the two sides are as follows (where as always a larger number means they prefer it)

Consider two similar industries, portal crane manufacturing (pcm) and forklift manufacturing (flm). the pcm industry has exactly three incumbents with annual sales of $800 million, $200 million and $100 million, respectively. the flm industry has also exactly three incumbents, with annual sales of $500 million, $450 million and $400 million, respectively. which industry is more likely to experience a higher level of rivalry?
