In a CAT LRDI caselet, which approach is generally LEAST efficient on the first pass?
ASketching a Venn diagram or 4 by 4 grid
BUnderlining each constraint as it appears
CListing what each question is asking
DSetting up algebraic equations immediately
Answer & Solution
Correct answer: D. Setting up algebraic equations immediately
CAT LRDI rewards quick sketches that expose constraints. Setting up algebra first tends to over-engineer the problem; a picture often answers the question without any equations.
