The school art department is planning to downsize the sculpture class from 30 students to 15. The change is made based on two reasons: firstly, small-scale classroom activities, a crucial part of art class activities, can only be done with no more than 20 students; if there are too many students, not every student can put his attention to the teacher’s instruction.Also, printing art materials is costly because large amounts of ink will be needeD、Thus, reducing the number of students can save some resources for further needs. Question: The woman expresses her opinion towards the school’s decision to reduce the number of sculpture class students. State her opinion and explain the reasons she gives for holding that opinion.
