Answer:
D. teaching
Explanation:
The trend for online learning seems to be on the rise following the pandemic. While one teacher could only directly interact with 30-60 students in a classroom, that's not necessarily the case with online learning. A teacher could handle hundreds or thousand of students in a pre-recorded material.
As a result, this create a negative effect on job availability in teaching. The number of teacher needed for this type of learning tend to be less compared to conventional education.
