Question

question #2
a student reads an article about two different technologies developed to predict earthquakes.
technology 1 issues a warning within one hour after the first tremor is detected. technology 2 issues a
warning within two to four minutes. the student claims that technology 2 will be more effective than
technology 1 and lists possible benefits of installing technology 2 for a city in a chart.

1. people would have extra time to seek shelter.
2. trains and nuclear power plants could be switched off safely.
3. buildings at risk could have their structures modified.
4. scientists would get time to reduce the intensity of seismic waves.

which benefits would be a result of using technology 2?
a 1 and 2
b 2 and 4
c 3 and 1
d 4 and 3
question #3
earthquakes may damage property and cause injuries. the chart lists a few solutions
relating to the assembly of buildings.

1. constructing tall buildings to be rigid and far apart
2. designing buildings with strong foundations
3. developing emergency exits and evacuation plans for buildings
4. creating buildings with extra ventilation

which solutions can best help minimize the effects of earthquakes?
a 1 and 2
b 2 and 3
c 2, 3, and 4
d 1, 2, and 4

Explanation:

Question #2

Technology 2 gives a warning within two - four minutes.

• For statement 1: If there is more warning time (compared to Technology 1 which has a one - hour warning after the first tremor), people can have extra time to seek shelter.
• For statement 2: With more warning time, trains and nuclear power plants can be switched off safely.
• For statement 3: Modifying building structures is a long - term measure and not directly related to the short - time warning of Technology 2.
• For statement 4: Scientists currently do not have the ability to reduce the intensity of seismic waves in a short time (within a few minutes) after a warning.

• For solution 1: Constructing tall buildings to be rigid and far apart is not a good solution. Rigid buildings are more likely to collapse in an earthquake.
• For solution 2: Designing buildings with strong foundations helps the building withstand the shaking of an earthquake.
• For solution 3: Developing emergency exits and evacuation plans for buildings allows people to escape quickly during an earthquake, reducing injuries.
• For solution 4: Creating buildings with extra ventilation has no relation to minimizing the effects of earthquakes.

A. 1 and 2
