A company has developed a new sensing device that, according to the company's claims, detects weak, ultralow-frequency electromagnetic signals associated with a beating heart. These signals, which pass through almost any physical obstruction, are purportedly detected by the device even at significant distances. Therefore, if the company's claims are true, their device will radically improve emergency teams' ability to locate quickly people who are trapped within the wreckage of collapsed buildings.

Which of the following, if true, most strengthens the argument?


A. People trapped within the wreckage of collapsed buildings usually have serious injuries that require prompt medical treatment.

B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings.

C. Most people who have survived after being trapped in collapsed buildings were rescued within two hours of the building's collapse.

D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction.

E. Extensive training is required in order to operate the device effectively.

IMO choice B is correct as it eliminates a circumstance in which the conclusion that the device can help locate quickly people is wrong.

A. People trapped within the wreckage of collapsed buildings usually have ((serious injuries)) that require prompt medical treatment. - seriousness of injury is irrelevant. We need a point which strengthens the conclusion that this device can locate people trapped in the wreckage of collapsed buildings. Eliminate.

B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings. - this strengthens the conclusion. It also eliminates the possibly that the device might locate any plant or other small insects trapped within the collapsed building. Thus, a probability of potential disadvantage is eliminated.

C. Most people who have survived after being trapped in collapsed buildings were rescued within two hours of the building's collapse. - irrelevant.

D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction. - OOS.

E. Extensive training is required in order to operate the device effectively. - OOS too.

Thus, B is best.

With POE technique, I eliminated A, D, E and zeroed in on B & C.
Conclusion is that new device has improved ability to detect quickly human in wrecked building.
B is strengthening the conclusion, stating that device gives distinctive reading after detecting human heartbeat from other livings.

It was between B and D according to me other options are out of scope.

D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction-- This option does not tell whether the frequency of human heart can pass. Apart from the electromagentic signals there can be numerous signals which pass but we don't have any evidence that will suggest heart signals can.

B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings.---There might be a dog trapped under the building too thus this assurance strengthens the fact that the instrument can be used.

Argument: Sensing device can detect ultralow frequency EM signals from the heart. So, the sensing device will greatly improve the detection of people trapped in buildings.

We need to support the above claim.


Which of the following, if true, most strengthens the argument?


A. People trapped within the wreckage of collapsed buildings usually have serious injuries that require prompt medical treatment. This choice gives us no reason to believe the sensing device will help in detecting people. Eliminate.

B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings. Looks good. This means the team locating trapped people will not be confused by heartbeats of other living beings such as pets. Definitely makes me believe that the sensing device could help quickly locate people

C. Most people who have survived after being trapped in collapsed buildings were rescued within two hours of the building's collapse. So what? Does not shed any light on the effectiveness of the sensing device. Eliminate

D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction. Again a fact that doesn't talk about the effectiveness of the sensing device

E. Extensive training is required in order to operate the device effectively.Again does not increase our belief in the effectiveness of the device. Eliminate.

These signals, which pass through almost any physical obstruction, are purportedly detected by the device even at significant distances.



Which of the following, if true, most strengthens the argument?


A. People trapped within the wreckage of collapsed buildings usually have serious injuries that require prompt medical treatment.
Out of scope

B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings.
Correct: In line with original Reasoning

C. Most people who have survived after being trapped in collapsed buildings were rescued within two hours of the building's collapse.
Out of scope

D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction.
Out of scope

Out of Scope since it doesn't talk about the device.

B. The device gives a distinctive reading when the signals it detects come from human beings rather than from any other living beings.
Correct Answer.Talks about how people can be detected quickly by the device.

C. Most people who have survived after being trapped in collapsed buildings were rescued within two hours of the building's collapse.
Out of Scope since it doesn't talk about the device.

D. Ultralow-frequency signals are not the only electromagnetic signals that can pass through almost any physical obstruction.
Out of Scope since it doesn't talk about the device. It only talks about an ultra-low frequency signal. It's also mentioned in the premise.

E. Extensive training is required in order to operate the device effectively.
Out of Scope since it talks about training required to use the device as opposed to the effectiveness of the device itself.

Hi,
The conclusion says that " their device will radically improve emergency teams' ability to locate quickly people who are trapped within the wreckage of collapsed buildings."

The key is the ability to detect human in the collapsed building.
For choice B, it eliminates the possibility that the device can detect other living things. If the device can detect animals, then this device cannot help to save human.

Hope this will help

NEW question from GMAT® Official Guide 2019


(CR01368)


PREMISE: New sensor detects signals from beating heart
PREMISE: Signals pass through almost everything
CONCLUSION: New sensor will help locate trapped people quickly

Now let's examine each answer choice while reminding ourselves of the conclusion.

A) Does this strengthen the conclusion that the new sensor will help locate trapped people quickly?
No, the conclusion is concerned only with the new sensor's ability to locate trapped people. Whether or not those people have serious injuries has no bearing on the conclusion. As such, answer choice A cannot strengthen the argument. ELIMINATE A.

B) Does this strengthen the conclusion that the new sensor will help locate trapped people quickly? YES! If it were the case that the sensor detected heartbeats from ALL living creatures, then emergency teams would waste a lot of time following signals emitted by non-human such as rats, mice or other animals with a heartbeat. So if the sensor detects only the signals from humans then the emergency teams will definitely be able to locate people quickly. KEEP answer choice B for now.

C) Does this strengthen the conclusion that the new sensor will help locate trapped people quickly? NO. ELIMINATE C.

D) Does this strengthen the conclusion that the new sensor will help locate trapped people quickly? NO. It makes no difference whether there are other electromagnetic signals that can pass through physical obstructions. ELIMINATE D.

E) Does this strengthen the conclusion that the new sensor will help locate trapped people quickly? NO. It makes no difference whether training is required. ELIMINATE E.

Answer: B

Cheers,
Brent
