Is there a specific example you have questions about? I'd be happy to help.
The Common Fallacies section is set up so that a specific flaw is described directly above a set of LSAT Errors in Reasoning questions. The flaw identified above the questions is the correct answer to each of the questions.
For example, the second flaw described is the failure to eliminate alternatives, which is where "the argument neglects to consider other possibilities."
The answer to the example problem directly following the description of this flaw is therefore (B) "fails to exclude an alternative explanation for the observed effect." This answer identifies the same principle as the flaw description above it does - a failure to eliminate alternatives.
Does that make sense? Please let us know if you have any other questions!
