Question 19 and 20 are based on the following reading passage.

A volcano can cause widespread damage, even when it\’s not erupting. An erupting volcano can cause ballistic showers of rocks, fast-moving currents of ash or lava called pyroclastic flows and acid rain. But even volcanoes that are not currently erupting can cause hazards — grounds around the volcano may be unstable and can cause landslides, for example. While these effects are most strongly felt near the site of an eruption, mudslides or floods can reach over 50 miles (80 kilometers) away, and ashfall can even reach areas 1,000 miles (1,600 km) away, according to the report. Although eruptions cannot be stopped, measures to limit exposure and enhance tolerance can make society less vulnerable to their effects. This includes evacuating hazard zones during an eruption, making infrastructure more resistant to its effects, swiftly cleaning up after the event and diverting lava or removing combustible material from its path. In the case of ash fall, people can wear particle masks, avoid driving, seal off buildings, shelter livestock, and shelter in place.

The passage is primarily concerned with discussing which of the following?

(A) Only about the effects of volcanoes.
(B) The effects of pyroclastic flows and acid rain.
(C) The effects of the volcano as well as the safety measures for society around the volcano.
(D) Only about the preventive measure for the volcanic eruption.
(E) The effects of the volcano as well as the preventive measures to stop a volcanic eruption.


Answer: (C)

Explanation: The passage is primarily concerned with discussing the effects of the volcano as well and measures to limit exposure and enhance tolerance can make society less vulnerable to their effects.
