Question

Tsunamis are rare events often accompanied by advance warning. Where horizontal evacuation out of the tsunami inundation zone is neither possible nor practical, a potential solution is vertical evacuation above rising waters into buildings and other structures with the strength and resilience necessary to resist the effects of tsunami waves. A vertical evacuation refuge is a structure or earthen mound designated as a place of refuge in the event of a tsunami, with sufficient height to elevate evacuees above the tsunami inundation depth, designed and constructed to resist tsunami load effects.

The average, healthy person can walk at approximately 4 miles per hour. However, some members of the community may have restricted ambulatory capability due to age, health, or disability. The average pace (ambulatory speed) of a mobility-impaired population can be assumed to be 2 miles per hour.

  https://gmatclub.org/gmat-focus-tests/resources/import/img/I02-22.pngStructure No. 1 is located adjacent to the harbor and a container terminal. Impact forces from ships, barges, boats, shipping containers, and other waterborne debris have the potential to be very large. Locations with additional sources of large, possibly buoyant, debris increase the chances of impact by one or more waterborne missiles, and increase the potential risk to the structure. 
 
 Structure No. 2 is located off to the side of the harbor and adjacent to a parking lot. This structure would need to be designed for debris consistent with the use of the parking lot and surrounding areas, which could include cars, trucks, and recreational vehicles. 
 
 Structure No. 3 is immediately adjacent to a gas station. In past tsunamis, ignition of flammable chemicals or other floating debris has resulted in significant risk for fire in partially submerged structures. 
 
 Structure No. 4 is adjacent to a waterfront park facility. This location can be ideal, as the potential for waterborne debris can be relatively low. Possible hazards could include debris from park structures, naturally occurring driftwood, or larger logs from downed trees. This area has a higher potential for tourists and visitors unfamiliar with the area and would require additional signage to inform park users what to do and where to go in the event of a tsunami warning. 
 
 Structure No. 5 is adjacent to an emergency response facility. Co-locating at such facilities can provide opportunities for direct supervision by law enforcement and monitoring and support of refuge occupancies by other emergency response personnel. 
 
 Structure No. 6 is intended to aid evacuees in taking advantage of naturally occurring high ground at two locations.

I just dont get the first one. As the individual is equally distant from 3 and 6, he should go to 6 because he is closer?

Does not make any sense

TetyanaRokobit · Answer

Official Solution:

Regardless of exact location in-between the gas station and a vertical evacuation route, site #3 will be closer to reach in response to a mid-source-generated tsunami.
 
Regardless of exact location in-between the gas station and a vertical evacuation route, site #2 will be closer to reach in response to a far-source-generated tsunami.
 
Regardless of exact location in-between the gas station and a vertical evacuation route, site #4 will be closer to reach in response to a mid-source-generated tsunami.

Correct answer:

An individual in-between and equally distant from the gas station and a vertical evacuation route seeks refuge at site #6 in response to a mid-source-generated tsunami.  "Not advisable"

An individual in-between and equally distant from the gas station and the container terminal seeks refuge at site # 1 in response to a far-source-generated tsunami.  "Not advisable"

An individual in-between and equally distant from the parking lot and the police / fire station seeks refuge at site #4 in response to a mid-source-generated tsunami.  "Advisable"

oman573 · Answer

I misinterpreted these questions as asking if they could possibly seek refuge.

Rather I should have interpreted it as actually seeking refuge based on proximity in the map?

It is hard to tell.

arkaja11 · Answer

I have the following reasoning:

1. If an individual in-between and equally distant from the gas station and a vertical evacuation route, it is "Advisable" to seek refuge at 6. Why is it wrong?
2. Far-source-generated tsunami, hence advisable to move to site 6. Agreed with the answer.
3. If an individual in-between and equally distant from the parking lot and the police / fire station, why structure 5 is not better than structure 4?

dishiii · Answer

I agree with the first one, keeping the conditions in check it's highly likely the 1)is advisable, for 3) however, if you look closely, 4 will be closer it's a mid source generated tsunami so the individual might or might not have the time to reach 6. However, 4 still seems like a safe option hence given the conditions it's advisable.
