Lets look into Argument Breakdown
* Premise 1: Dental surgery is complex.
* Premise 2: Government-subsidized (GSHS) surgeons are usually inexperienced.
* Premise 3: Inexperienced GSHS surgeons make errors that experienced ones don't.
* Premise 4: These errors can cause unpleasant nerve damage.
* Conclusion: Therefore, people should use private surgeons (who are implied to be more experienced) even if it costs more.
The core of the argument is: Avoid GSHS surgeons because they are inexperienced, which leads to a risk of errors causing nerve damage. The conclusion asks you to pay more money to avoid this specific risk.
Now lets evaluate the Options
* A. To become certified dental surgeons, students must first be accepted into specialist programs which require extremely high grades and references given by supervising surgeons.
* This describes the high standard for all dental surgeons (both private and government). It doesn't strengthen the difference between them or the reason to prefer private.
* B. Almost 80% of the procedures performed by dental surgeons do not require incisions deep enough to pose a threat to nerves in the gums.
* This weakens the argument. If the risk of nerve damage is actually very low for most procedures, then the argument's central reason to pay more (avoiding nerve damage) becomes less significant.
* C. A decrease in the number of consultations with government surgeons will lead to an increase in the price of government-subsidized dental health services.
* This discusses a potential consequence of following the advice, not a reason to follow it. It's irrelevant to the medical justification for the conclusion.
* D. Structural damage to nerve fibers, resulting in discontinuous neural communication, is usually irreversible.
* This strongly supports the conclusion. The argument hinges on the idea that "unpleasant nerve damage" is a risk worth paying extra to avoid. If this damage is not just "unpleasant" but also permanent and irreversible, the risk becomes much more severe. This makes the recommendation to pay a higher price to avoid it (by choosing a more experienced private surgeon) far more logical and compelling.
* E. Technological advancements in the dental health sector simplify procedures and allow surgeons to avoid making mistakes.
* This is a general statement. If anything, it might weaken the argument by suggesting that technology helps all surgeons (including the inexperienced ones) avoid mistakes, thereby reducing the risk gap between government and private surgeons.
The correct answer is D. It supports the argument by increasing the severity of the risk that the argument's conclusion is designed to avoid.
Bunuel
Dental surgery encompasses many complex procedures that require years of training and experience to perform correctly. Surgeons working for government-subsidized health services are usually inexperienced and have been known to commit errors that experienced surgeons would not. Since such errors can result in unpleasant damage to nerves in the mouth and jaw area, people that need dental surgery should consult private surgeons even if it necessitates paying a higher price.
Which of the following, if true, supports the argument's conclusion?
