Today's Daily Drill is, just like yesterday's, a mock Inference Question. Why the same question type back to back? Because the newly released official SAT® practice tests show an increased emphasis on these questions. While the drill follows the digital SAT® format,¹ it’s also great practice for ACT® Reading.
