It is true that students who do the majority of their learning on computer screens from a young age can be at a higher risk of developing myopia later in life, with the most significant risk being increased risk of degenerative myopia as a result of too much near-work. Classroom-based learning which does not involve computers represents the traditional alternative to the growing popularity of e-learning. It provides face-to-face “real-world” instruction, which allows students’ vision more depth-of-field variety as instruction occurs. Therefore, non-computer-based learning is a better alternative to e-learning for young students and their visual development.
Which of the following is an assumption upon which the argument depends?
A- If given the choice, students will continue to work on computers rather than in the “real world” even after they report some eye strain.
Students preference doesn't affect the passage the slightest
B- Eye function is hindered less by depth-of-field variety learning than by near-work.
If it hinders more then there is no purpose of advocating face to face learning
C- Eyes are not damaged in similar ways working on a computer screen and reading a textbook.
Reading isn't taken up in the passage so provinding support for the same doesn't help much
D- The risk of myopic damage caused by prolonged focus on screens is unacceptably high.
This is simply restating and Gmat doesn't prefer strong words and wide proclomations
E- Some computers cannot be programmed to stimulate wider depth-of-field at regular intervals to counter-balance any prolonged eye strain
Some doesn't help the wider no of computer that's taken into question
Therefore IMO B
