Answer:
If a certain nation decided to stop importing goods and commodities, it would have an almost immediate negative impact on its economy. Thus, from this brake, the supply of goods that were originally imported would be significantly reduced, with which they would drastically increase their value, thereby increasing inflation in the country.
In addition, citizens could not easily access these goods, which could produce social consequences (such as lack of medicines, for example).
On the other hand, the producing nations of these goods would impose trade restrictions on the nation, which would reduce the benefits of trade, increasing the country's fiscal deficit.
We can reject answers C) and D) :those are two famous cities in Russia, and cities would be too small to take up three-forths of Russia, the biggest country in the world.

Answer:
Fissure eruptions
Explanation:
A fissure vent or eruption fissure is a linear volcanic vent from which lava erupts mostly without explosive activity. The vent is usually not very wide but can be very long stretching for miles. While they do not explode like many volcanic cones do, fissure vents can cause large flood basalts. After some time the eruption builds up spatter cones and may concentrate on one or some of them. Spatter cones are steep-sided hills that consist of welded lava fragments that are called spatter and these cones form around vents.
