jabhatta2 that would certainly help, yes. But the question asked what would be most useful to know. So even the correct answer could lead to some follow up questions in our evaluation of the argument - the correct answer won't necessarily tell us all we want to know.
If we find out that a very large proportion of schoolchildren in Harnville with hand and wrist injuries use computers extensively outside the classroom, we'd probably have some follow up questions, such as what's their posture like?
If we find out that a tiny proportion of schoolchildren in Harnville with hand and wrist injuries use computers extensively outside the classroom, we wouldn't have any follow up questions about their posture at home.
Either way, yes, it would be useful to know what proportion of schoolchildren in Harnville with hand and wrist injuries use computers extensively outside the classroom.

Please compare the above (main) question with the question in the link
For the question in the link - Option D was eliminated because This scenario (SDV machine are not placed in cafeteria) is not in discussion
https://gmatclub.com/forum/although-the ... 02757.html
For the above (main) question - OA is option C, however aren't we discussing the situation at school? and should it be eliminated? I understand both questions are different but the concept should be the same right?

No two CR questions are comparable. We don't list down "rules" for you to follow while solving CR because we cannot set them. The "concept" you mention depends on what is given in the argument. One word could make all the difference. You cannot simplify by saying "so and so is not reasonable logic."
Observe whether it is reasonable logic in the given context.
Besides, the two questions are looking for very diff things. One is looking for "useful to evaluate" and the other is looking for an assumption. An assumption must hold for the conclusion to be true.
Note in the link question (Useful to evaluate):
"teachers plan to bring about a sharp reduction in the number of these injuries by carefully monitoring their students' posture when using computers in the classroom."
The injuries won't drastically reduce if they are maintaining bad posture extensively outside. So option (D) is valid.
Note in this question (Assumption):
Allowing soft drink machines in Cafeteria would not be in our students' interest.
If our students start drinking more soft drinks, they will be less healthy.
Conclusion: Don't allow soft drink machines.
Our premise is a condition - 'if our students start drinking more soft drinks...'
To conclude that we shouldn't allow soft drinks, first thing we must do is say that they WILL start drinking more soft drinks. Only then can we reason about less healthy and not in their interest. Hence the entire argument depends on whether they will start drinking more soft drinks. What if installation in school leads to reduction in soft drink consumption because of abundant availability and hence fewer cravings etc? Hence option (A) is an assumption.
Students bringing soft drinks from home is simply status quo because currently soft drink machines are not there. We don't need to assume that they don't bring soft drinks from home or won't bring in future if the same situation is maintained.
Our point is will they start drinking "MORE" soft drinks if machines are installed in school? Hence option (D) is not assumption.
