Request you to share your comments on the below point-
I have been studying CR for sometime, and have seen one strategy point for Weaken Question. Strategy says that your job is to undermine the conclusion not to disprove it. Can someone share inputs on how undermining the conclusion is different than disproving it.
It would be really great if an OG example can be taken for this.
Thanks

To undermine something means to erode its foundation - in CR, anything that undermines the conclusion creates a valid doubt about whether the conclusion is true. This may happen without the conclusion really being proved false in an unassailable way.
The conclusion states that the fact that three hospitals out of four prescribe Novex means that Novex is the most effective painkiller. How do we undermine this? By proving that the hospitals may be prescribing Novex due to some reason other than Novex being the most effective.
Choice C provides us this reason - if Novex is being sold at a very low price to hospitals, then this may be the reason why hospitals are prescribing it - not because Novex is the most effective painkiller. This answer choice undermines the conclusion that it is the effectiveness of Novex that leads it to be prescribed by the hospitals. The answer choice does not necessarily disprove that Novex is the most effective - for all we know, it may be the most effective and the cheapest, and gets prescribed because it is effective, not because it is cheap. That possibility still exists. However, answer choice C does significantly call into question the conclusion that Novex is the most effective. Thus answer choice C undermines the conclusion without disproving it.
