In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was 10 years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

(A) A few children still use traditional wooden sleds.
(B) Very few children wear any kind of protective gear, such as helmets, while sledding.
(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
(E) Because the traditional wooden sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

Ok I get it now.

According to the argument -"plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous"
To summarize, plastic sleds are dangerous becuase they are faster than wooden sleds and hence are more dangerous.

Now we need an answer choice that undermines the force of the evidence cited. Meaning we need an alternate reason to explain why Plastic sleds are dangerous than the wooden sleds.
C explains it best.

Let us see why others are not good choices.

A,B,D,E- doesnot explain why plastic sleds are dangerous

Hey All,

The one thing I try to avoid when reviewing is writing off too many answer choices as "no effect" or "out of scope". This tends to ignore the subtlety of certain answer choices, and leads one to an attitude of ALL or NOTHING in terms of answer choices. Dangerous.

Conclusion: Plastic sleds are more dangerous than wooden sleds.

Premises: In past 10 years, plastic sleds have become more popular than wooden. More children injured on sleds now than 10 years ago.

Already, you should be able to see the assumption. We jumped to danger, without considering any other factors

Assumption: Some other factor is responsible for the jump in injuries (more people using sled, for example).


(A) A few children still use traditional wooden sleds.
PROBLEM: This doesn't weaken the argument. In fact, this is the argument. The whole idea is that lots of people are using plastic sleds, which are dangerous. A few children doesn't change that.

(B) Very few children wear any kind of protective gear, such as helmets, while sledding.
PROBLEM: This doesn't compare wooden sleds to plastic sleds, so doesn't explain why one might be more dangerous.

(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
ANSWER: Now the plastic sled can get used a lot more often. This would explain why there are so many more injuries, because there's a lot more sledding going on. The argument that plastic sleds are more dangerous is now unlikely.

(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
PROBLEM: Like B, this doesn't differentiate between wooden and plastic sleds.

(E) Because the traditional wooden sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
PROBLEM: We want to weaken the argument that plastic sleds are dangerous. Making wooden sleds hurt more people doesn't actually affect that. If anything, this strengthens the argument. If multiple people could get wounded on one wooden sled, then why would the #s be EVEN HIGHER for injuries on a plastic sled?

Hope that helps!

Just bc a few kids still use wooden sleds does not weaken the argument, we want to attack the idea that plastic sleds are more dangerous
(B) Very few children wear any kind of protective gear, such as helmets, while sledding.
This could work, Keep for now. But, the thing is, wouldn't wooden sled kids and plastic sled kids generally both not use protective gear? Probably not right.
(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
Ok, so this could work in that maybe wooden sleds are only good for perfect snow, while plastic ones can be used in all types (good and bad) which may lead to higher injury rates, but not due to the plastic sleds but rather due to using sleds in unsafe conditions
(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
This doesn't really mean anything and nothing can be differentiated between wooden and plastic sleds.
(E) Because the traditional wooden sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
Ok, so this does undermine the argument in that wooden sleds can hurt multiple people, but we want to attack why plastic sleds are more dangerous. In this case, C works better

Regarding C
You are saying that since plastic sleds can be used in more number of ways => more injuries.
How is this weakening the argument rather than strengthening ?



Lemme givve my 2 rupees(LOL)

Anyways :- the Stimulus says that 10 years ago Plastic Sledges became popular.

And that since the NUMBER of injuries have increased the Plastic Sledge is dangerous.

What is assumed is either the number of Sledges are Same as with Wooden Sledges

and the usage is same then only we can compare the injuries.

What if the usage has increased so much that the %age per sledge has gone down.

Lets say

in 2000 - 100 Wooden sledges were in use and 100 injuries were reported hence Per Sledge Injury is 1

Lets say in 2015 2000 Plastic Sledges were used :- and 200 Injuries were reported Per Sledge Injury is now .1

By this number the Injury Rate is lower for the Plastic Sledge,but the sheer increase in use has made the increase in Injuries.

The Point C makes is it not just used for leisure, but for towing wood, it is used to manually push many cartons... The usage has increased so much that many new injury factors have included.... Hence the sledge might not be as unsafe for the children as the wooden one.

PS. And Also the Bottom Line :- When a Safety, Profit Rise,Trend or any kind of Resultant Characteristic is compared its almost always is about proportion, so attack the proportion.

I hope it helps...

Cheers

I choose the wrong option B but, could someone please help correct my point of view

(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can. - Plastic boards became popular 10 years ago. So they probably might have used it for variety of snow conditions back then as well. But last winter they have witnessed more injuries when compared with injuries that occurred 10 years ago, here they are comparing the injuries caused due to use of plastic boards (current and 10 years ago when plastic boards are being used). which implies that something else is a factor of increased injuries.

(B) Very few children wear any kind of protective gear, such as helmets, while sledding. - as we are comparing injuries sustained last winter by using plastic boards to those injuries that were sustained for using plastic boards 10 years ago, an additional/external factor would be as given in this option isnt it.

Thanks in advance for your help
The mistake in your analysis of option C is that you're making a "plastic to plastic" comparison. Instead, look at the number of accidents 10 years ago as "wooden sleds" and the number of accidents last winter as "plastic sleds". So what we want to say is that plastic sleds can be used more often (and probably on worse types of snow) than wooden sleds can. Hence the number of accidents has gone up (the plastic sleds might actually be safer, and increased usage can account for the increase in the number of children injured).

If children generally don't wear protective gear, and the number of injured children has gone up, then it is more likely that the (plastic) sled is to blame.

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was 10 years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

(A) A few children still use traditional wooden sleds.
- out of scope. not concerned whether children CAN STILL USE wooden sleds...issue is whether they're more/less dangerous than plastic sleds.

(B) Very few children wear any kind of protective gear, such as helmets, while sledding.
- out of scope. children can use protective gear for wooden or plastic sleds.

(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
- if plastic sheds can be used in a much wider variety of snow conditions than wooden sleds can, there's a much higher likelihood that there are accidents with plastic sheds -- strictly probability.

(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
- OPPOSITE. this STRENGTHENS evidence. Why? B/c passage says that plastic sleds are harder to steer and go faster...this increases the odds that plastic sleds can collide with other things.

(E) Because the traditional wooden sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
- OPPOSITE. this STRENGTHENS evidence. Why? Because if wooden sleds can carry more than one rider, AND more injuries occur since the increase in popularity of plastic sleds, this further solidifies that plastic sleds are more dangerous than wooden sleds.

kudos please if you find this helpful :)

Summarize the argument..

PREMISE: Kids used to use wooden sleds
PREMISE: 10 years ago, plastic sleds came
PREMISE: plastic sleds are faster and harder to steer and slow
PREMISE: more kids injured last year than 10 years ago
CONCLUSION: plastic sleds are more dangerous

Now, check each answer choice and be sure to remind ourselves of the conclusion

(A) A few children still use traditional wooden sleds.
Does this weaken the conclusion that plastic sleds are more dangerous than wooden sleds?
No.
If anything, it strengthens the argument by suggesting that most children ride on plastic sleds these days.
ELIMINATE A

(B) Very few children wear any kind of protective gear, such as helmets, while sledding.
Does this weaken the conclusion that plastic sleds are more dangerous than wooden sleds?
No.
IF it were the case that all/most children wore protective gear 10 years ago and, nowadays, they DON'T wear protective gear, then that would weaken the argument, since we could say that the lack of protective gear (and not the plastic sleds) caused the increase in injuries
However, since we aren't told that this is the case, we can ELIMINATE B

(C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
Does this weaken the conclusion that plastic sleds are more dangerous than wooden sleds?
Yes!
This means that children with plastic sleds can do A LOT MORE sledding than they can do with wooden sleds.
So, it seems that the increase in sledding opportunities (and not the plastic sleds) is what caused the increase in injuries
KEEP C

(D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
Does this weaken the conclusion that plastic sleds are more dangerous than wooden sleds?
No.
If anything, it strengthens the argument, since the difficult-to-steer plastic sleds will likely run into a lot more trees etc.
ELIMINATE D

(E) Because the traditional wooden sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
Does this weaken the conclusion that plastic sleds are more dangerous than wooden sleds?
No.
ELIMINATE E

Answer: C

Cheers,
Brent
