How is answer A incorrect and E correct? First, where in the passage is E supported? I can't find it. Next, doesn't A capture not only the main point of the passage but also Goodrich's prescription in lines 40-43 and line 45? Goodrich doesn't think that common law should be looked at as a set of rules (a legal code). Also, line 45 states that common law is a text with history and tradition, and in line 46, studying common law historically is really important. How does this not capture the idea of "a relic of the history of the English people?"
