sampathgelam · Answer

The question itself is wrong, as there is mention of percentages and in the table the total is not equal to hundred.

Score-Quest · Answer

1. We see that the percentage of Surgeons and even Paramedics wearing protective gear is higher than the veterinarian across all types of gears. This can be explained by "Humans catch diseases from other humans much more easily than from animals." Hence, the first statement "Would Help Explain" the information in the table.
2. We see that a higher percent of Construction Workers wear earplugs or hearing protection compared to Paramedics. This could be explained by "Ambulance sirens are loud, but they don't damage people's hearing as much as power tools do." Hence, the second statement "Would Help Explain" the information in the table.
3. There is no information in the table that can be explained by "About 10% of janitors earn extra pay for cleaning hazardous areas." Hence, the third statement "Would Not Help Explain" the information in the table.

Hi  sampathgelam , the percentages in this question do not need to add upto 100 because each number in the table is an individual percent. For eg., 4% of all Chemists wear Earplugs or Hearing Protection and 52% of all Chemists wear Goggles or Eye Protection.

Official Explanation

Statement 1:  This explain why veterinarians require less protective gear than surgeons and paramedics.

Answer: Would help explain

Statement 2:  This could explain why paramedics often need earplugs, but construction workers need them even more often.

Answer: Would help explain

Statement 3:  Only a small percentage of janitors are paid extra to clean hazardous areas. This does not explain why a fairly high percentage of janitors wear gloves.

Answer: Would not help explain

Number-percentage fallacy is not taken into account while creating this question. Either a sample size OR directly the number of people should've been given here. Just mentioning the percentages arbitrarily complicates the problem unnecessarily.

ajay0520 · Answer

but why should i need to know out side information( paramedic travels in ambulance) to answer second part of this question correctly?

Since  GMAT wont require us to require to be known of outside information , i think for Q2 the answer should be 'would not help explain'

can some one please clear this doubt of mine?

Kunal.lost · Answer

The percentage of construction workers getting an earplug/hearing protection is more than the percentage of paramedics getting it. So, it does help explain.

ajay0520 · Answer

That's what i am confused about, what does paramedic has to do with sound of ambulance? i think the question should mention that paramedic spend their day inside ambulance hearing its loud noise all the time and not anywhere else.

Kunal.lost · Answer

I agree. This question comes with an assumption that you know what these job roles are.

But on the exam, you won't see anything that'll assume you have a background on the subject.

So don't worry about it too much, as it's not an official question.
