This answer says the recommended height for computers differs between children and adults. But the argument already established that the computers are positioned too high for children — confirming that the standard is different and that the school computers do not meet the child-appropriate standard. If anything, acknowledging that children have different ergonomic requirements supports the claim that the current setup is problematic for them. This answer reinforces the premise that the computers are improperly positioned for children rather than undermining the conclusion about injury risk.

This answer says children spend more time on computers at home than at school. While this is interesting, its impact on the argument is uncertain. It could mean children accumulate more total exposure to bad posture, which might strengthen the risk claim. Or it could be irrelevant if home computers are better positioned. The argument specifically concerns school computers and their posture effects. Whether children face additional risks at home does not address whether school computer posture problems produce the same injury risk as office workers face. The argument's comparison is between school children and office workers, not between total child computer exposure and adult exposure.

This answer says office workers' computers are also not at recommended heights. If anything, this strengthens the parallel between children and office workers — both groups face improperly positioned equipment. The argument claims children face the same RSI risk as office workers. Showing that office workers also use poorly positioned computers supports the comparison by confirming that both populations experience similar ergonomic failures. To weaken the argument, we need a reason why the same posture problems do not produce the same risk, not additional evidence that the posture problems are comparable.

This answer says office workers are more likely to report injuries than children. But the argument's conclusion is about actual risk — the likelihood of developing RSI — not about reporting rates. Even if children underreport injuries, that does not change whether they actually face the same physiological risk. The argument is making a claim about biological susceptibility based on posture analysis, not about injury statistics based on self-reporting. Differences in reporting behavior might affect how we measure injuries, but the argument's conclusion is about whether the risk exists, not about whether it is documented.
