## Verbal - SC

Trivium Rule – Grammar, Logic, Style

Subject-verb Agreement – subjective clause, subject position, modifier

Parallelism – verb, noun, modifier, fake parallelism

Idioms – 30 common idioms and pitfalls

Pronouns – singular, plural, ambiguity, “this”

Assumption – missing evidence, assumption confirmation/negation test

Conclusion – “A+B=C”, contradiction, paraphase, quantitative (ratio, proportion, rate, mean etc)

Inference – differences with conclusion, over-inference

Evaluation – quantitative, qualitative (=assumption)

Logical Flaws – sample bias, different baseline, hasty generalization, suppressed evidence, false cause

General Requirements – direct and straightforward, no absolute words in conclusions/inference, reference case not valid for weakening, linkage between evidence and conclusion, hit key points in evidence
