Hydraulic rescue tools, colloquially known as Jaws of Life, are used

OA and OE will be posted by tomorrow...

Archit

My take is E..

reason...

Emergency response workers prefer hydraulic tools, not only because they are less frightening to crash victims, but also because............................................

A) One hydraulic rescue tool can perform the functions of both a crowbar and a circular saw...this means there is one hydraulic tool that performs the function of the two other tools..too specific..
B) Hydraulic tools are quieter and do not cause crash victims to panic...already stated in the first part of the sentence.
C) Hydraulic tools are unlikely to complicate an already dangerous situation in the way that more traditional tools often did...this means hydraulic tools does not complicate the danger in the way traditional tools did BUT it does complicate in some other manner..
D) Hydraulic tools are able to quickly and efficiently repair structural damage to vehicles involved in collisions..not concerned with repairing...
E) Emergency response workers have greater leverage when using hydraulic tools than when using traditional tools, such as crowbars and circular saws...correct...

whats OA..??

Fact 1: The Jaws are used by emergency to remove victims from crashed vehiciles.
Fact 2: Traditional tools such as crowbars and circular saws have often been completely replaced by the Jaws.
Fact 3: Unlike the traditional tools, the Jaws do not cause additional structural damage nor create sparks.


Fact 2 proves that this is the right answer.

Panic is not part of the argument. This statement is an assumption.

Hydraulic tools do not cause additional structural damage nor create sparks - Fact 3. However, it does not mean that hydraulic tools are unlikely to worsen the situation (in the same way, naturally). They are less likely to do that than traditional tools, because they eliminate these two risks, but not unlikely.

Nothing like that is stated in the argument. Repairing is out of the question.

Nothing on the leverage in the argument.

This is a question where no additional information is permissible. We need to use the premises to arrive at a conclusion. Based on that C seems best as the premise clearly mentions that traditional tools complicates a situation due to structural damage/sparks. So, C seems best.

A: Outside info
B: Outside info
D: Repairing structural damage is not the priority. Extracting victims of the crash is.
E: Outside info

In these kind of question we need to look for a choice which takes passage to logical conclusion.
Now the author has given following as reasons why Hydraulic tools are preferred:
1. Traditional tools could cause additional structural damage or create sparks.
2. Hydraulic tools are less frightening to crash victims.

So the line of thinking is Traditional tool cause additional structural damage and creates spark so frightening to crash victims while hydraulic tools are less frightening to crash victims.
Another reason in the same line should be the answer.

Choice A is taking about the function but not why using one hydraulic is better than using two traditional tools so can not be the answer.
Choice B is just the repetition of point 2 above and hence can’t be the answer.
Choice C talks about how hydraulic tool is better in the same line as point 1 and 2 and hence is the best choice.
Choice D is again out of scope as passage is not taking about vehicle but about rescue of victims.
Choice E is not direct enough to give a good reason as compared to choice C.

The answer is C

A One hydraulic rescue tool can perform the functions of both a crowbar and a circular saw.
Wrong. Does the tool need to perform these functions to rescue? The passage already cites an issue with these tools
B Hydraulic tools are quieter and do not cause crash victims to panic.
Wrong. The author is trying to cover a new point after 'but also because' hence will not repeat the victim issue again
C Hydraulic tools are unlikely to complicate an already dangerous situation in the way that more traditional tools often did.
Correct. The author clarifies the doubts in the mind of reader by nullifying the issue with the traditional tools and fits in well after 'but also because'
D Hydraulic tools are able to quickly and efficiently repair structural damage to vehicles involved in collisions.
Wrong. Off track answer, the passage doesn't talk about repair of the damage.
E Emergency response workers have greater leverage when using hydraulic tools than when using traditional tools, such as crowbars and circular saws.
Wrong. The passage doesn't talk about the lack of leverage with traditional tools

So C is the correct one , Please share OA and OE

Hi,

In this question, we are asked to fill in the additional advantage of the Hydraulic tools, which must be different from the first one, over the old tools. Be minded that we need to find an additional reason to choose Hydraulic tools because of the conjunction couples: not only ... but also.
So let's evaluate each choice.
A - One hydraulic rescue tool can perform the functions of both a crowbar and a circular saw. => already mentioned as a premise in the argument -> eliminate A
B - Hydraulic tools are quieter and do not cause crash victims to panic. => already mentioned as the first reason for choosing the Jaws over the others. -> eliminate B
C - Hydraulic tools are unlikely to complicate an already dangerous situation in the way that more traditional tools often did. => matched what we are looking for -> keep this choice
D - Hydraulic tools are able to quickly and efficiently repair structural damage to vehicles involved in collisions. => the argument is about tools to remove victims from crashed vehicles so this choice is out of scope -> eliminate D
E - Emergency response workers have greater leverage when using hydraulic tools than when using traditional tools, such as crowbars and circular saws. => more leverage then what? this choice does not provide a clear edge of using Hydraulic tools > eliminate D

Only C is left.

Hope this helps.

is there any conclusion in this question stem? or we just need to identify additional premise?
