Question

consider this claim:
tablets should not replace textbooks because overuse of tablets can cause health problems for students.
which is the strongest evidence to support the claim?
some studies have found that usage of portable electronic devices is associated with increased rates of musculoskeletal disorders.
many educators have found that tablets in the classroom, which are usually equipped with a web browser and a variety of applications, can be a source of distraction.
\many of my students complain about headaches, which i believe are caused by too much time spent on their tablets,\ said eighth-grade science teacher greg stevenson.

Explanation:

The claim focuses on tablet overuse causing student health problems. The first option provides peer-reviewed study evidence linking portable electronic devices (like tablets) to a specific physical health issue (musculoskeletal disorders), which is objective and generalizable. The second option addresses distraction, not health. The third is an anecdotal teacher's observation, which is less rigorous than formal studies.

Answer:

Some studies have found that usage of portable electronic devices is associated with increased rates of musculoskeletal disorders.
