Digital SAT Command of Evidence Questions: Practice Drill #6
Struggling to master dSAT Reading & Writing? Improve your score with this expertly-crafted example question. Includes strategy tips and detailed answer explanations!
Welcome to this week’s SAT Reading & Writing practice drill, tailored for those looking to conquer dSAT “Command of Evidence” questions. I've coined a term that I think better encapsulates the essence of this question type: Logical Operations: Support (LO:S). These questions are not just about using your general intuition to identify supporting evidence; they require a more nuanced understanding of the logical mechanisms that make arguments valid and sound.
Though this LO:S drill features a table, the core skill remains the same—backing up a statement with solid support. That said, infographics do add some extra layers to the general strategy. To master these, dive into my comprehensive guide on LO:S questions.
