Load factor--the first answer option is correct--is a standard indicator of utility business efficiency, and historically important for transportation history. Perhaps in class, a historical example included data from Buffalo or Cleveland, but not Pittsburgh, and was presented alongside other considerations of public utility businesses.

LMS-based exams and quizzes have additional features unavailable to their paper antecedents. You can have multiple-choice questions immediately, or perhaps after a certain time frame, provide feedback to students. When students chose the wrong answer they can be shown the correct answer, with perhaps additional commentary on both write and wrong choices. This can save you time grading, as well.
