The correct answer is - days or years before the major earthquake.
The foreshocks always come before the major earthquake. They can appear only a single day before it, weeks, months, or even years. It is a nice indicator that something bigger is coming, so if people are wary enough they can avoid the devastating effects of the major seismic activity afterwards.
For example, we can take the foreshocks and the major earthquake in Ohrid, Republic of Macedonia, in the summer of 2016, where the foreshocks started about two months earlier, and they were present every day for those two months, slightly increasing in intensity, until the major earthquake of 6.9 magnitude according to the Richter scale came.
Small foreshocks that precede a major earthquake occur days or years before the major earthquake.
Further Explanation:
Earthquake refer to sudden shaking of the ground violently due to volcanic action or movement within the crust of the earth.
Foreshock: It is an earthquake that occurs before occurrence of a large seismic event or earthquake. It is related to space and time. The observation of the foreshocks that are associated with the earthquake reveals that the foreshocks forms a part of the preparation process to nucleation. When earthquake rupture, the process forms a cascade of events, starting from small events like foreshocks that triggers the large events and continue till main shock is triggered.
Example: The 2002 Sumatra earthquake is considered as the foreshock for the 2004 Indian Ocean earthquake and time difference between two events is more than two years.
Therefore, small foreshocks that precede a major earthquake occur days or years before the major earthquake.

Answer:
Italy
Explanation:
The European country that experiences the greatest seismic activity is Italy. The seismic activity is manifested through both volcanic eruptions and earthquakes. The reason for this is that Italy is located near the boundary between the Eurasian and African tectonic plates. This boundary is a very complex collision boundary, where there is lot of pressure between the two continental plates, causing constant adjustments in the crust, resulting in constant earthquakes. Also, there are volcanoes, which have emerged on the land. Vesuvius and Etna are actually one of the best known volcanoes in the world, with Etna being one of the most active volcanoes in the world.
B. Level of education of the country's citizens
C. Climate of the country
D. Major religion of the country
Answer:
D
Explanation:
It is D because it makes the most sense. Also because the Climate doesn't matter for power. The level of education doesn't really matter for have power on individual nations. Also because Females and Males both count when it comes to countries modern day.
