(A) Tooth enamel can be chipped in sports accidents.
(B) Grinding and clenching both have the same effect on tooth enamel.
(C) Tooth enamel is an extremely hard substance.

IMO C.
The assumption in this argument are :-
1. that teeth is a hard substance
2. people who do not clench/grind their teeth do not come across an equally hard substance as teeth.
But somehow I feel the answer which I have selected becomes an assumption.
Let me know what do you think.

The argument starts out by saying -
The attrition of tooth enamel stems from erosion, which occurs only when teeth grind against hard substances.
and then continues to say - "those who regularly clench or grind their teeth together will suffer higher rates of enamel attrition "
If we can show that the tooth enamel can be categorised as "hard substances" , then the conclusion will get more support .

Question #9 (incorrect)
The attrition of tooth enamel stems from erosion, which occurs only when teeth grind against hard substances. Therefore, those who regularly clench or grind their teeth together will suffer higher rates of enamel attrition than those who do not.
Which of the following most strongly supports this argument?
(A) Tooth enamel can be chipped in sports accidents.
(B) Grinding and clenching both have the same effect on tooth enamel. The premise says erosion occurs when teeth grind against hard substances. Conclusion: Those who regularly clench or grind their teeth together will suffer higher rates...
Since the premise only talks about grinding, while the conclusion talks about both grinding and clenching, it must be that both have the same effect on tooth enamel.
(C) Tooth enamel is an extremely hard substance.
(D) Most people do not grind or clench their teeth together.
(E) Front teeth are more likely to grind against one another than back teeth are.

Why I think B is our conclusion is clenching or grinding together will suffer higher rates of enamel attrition.
notice important words here, highlighted in bold.
If I take only one then there will be some impact but not higher impact. If both processes have same impact and if I do both together then rates of enamal attrition will be higher. What if I know that both processess have the same effect and if those 2 processess I use together then effect will be higher.
Therefore, B looks fine here.

@Pradeep..answer cant be C
C will weaken this argument.If tooth enamel is an extremely hard substance than Grinding and clenching will not effect it much.
B is the only contender.

This is a weird question...
However, I do agree that the best answer available is C.
A/D/E are out in first glance because they're irrelevant to the argument , so it's down to B or C.
Conclusion: those who regularly clench or grind their teeth together will suffer higher rates of enamel attrition than those who do not.
(B) Grinding and clenching both have the same effect on tooth enamel.
This statement has almost zero bearing to the conclusion. The conclusion is stating that one group, those who clench or grind their teeth, will suffer higher rates of enamel attrition than another group, those who do not clench or grind their teeth. So whether clench/grind has the same effect within that first group do not challenge the conclusion at all; the group of people who clench/grind their teeth still have higher chance of suffering higher rates of enamel attrition.
I don't necessarily like C because it doesn't actually affect the conclusion, and C is unusual because a strengthening question typically affect the conclusion rather than the premise. So my view on this question is that I don't like it =).
