Hmm, sorry, but I don't agree. The problem you're facing is comprehension of word content, vs. analysis of the context to form a conclusion that may not be PART of the content. The example you cite is one that I'm not sure general reading will solve. To take A, B, and C and draw a conclusion may not be so much a question of comprehension of what you read, but of critical thinking skills that allows you to PRESUME things not actually in the text. This is a skill set that can only be learned by seeing other similar questions (as on a mock exam) and reading the answer repeatedly to understand what form of analysis is required.
For example, presume that all of the following facts are completely true:
Shirley is a blonde
Bill is a brunette
Most blondes are lawyers
Bill is a lawyer
then:
a) Shirley is a lawyer
b) Bill dyes his hair.
c) Both are true.
d) Neither is true.
While you may comprehend each of the statements, the critical thinking skills takes you beyond that to reach answer d). But you have to read the reason for the answer in the study guide to understand why. Does that make sense??
