A student writer is revising the passage below. Paragraph 1: An apprenticeship program is adding short math modules based on measurements, tolerances, and material estimates used at work. The goal is accurate workplace calculation, not general satisfaction. Paragraph 2: The draft proposes that the modules could improve apprentices' accuracy on job-related calculations. Its next sentence currently restates the proposal without adding information. Which option supplies the missing development for the writer's point that the modules could improve apprentices' accuracy on job-related calculations?
