Answer:
B. P waves can travel through liquids
Explanation:
P waves or primary waves are elastic waves produced from an earthquake. They are the first waves that arrives a Seismic station when an earthquake disturbs the earth.
P and S waves are both body waves that moves within the earth.
P- waves travel faster than S- waves and can propagate through any medium. S-waves or Secondary waves are shear waves that can only propagate through soilds.
Both waves are longitudinal and moves parallel to their source of propagation. They move by disturbing other particles in their line.
Transverse waves are the love and rayleigh waves. They are both surface waves that travels and cause disturbance on the surface of the earth during an earthquake. They move up and down.
I think that the question asks about the time of the War in Bosnia and other parts of Yugoslavia in the first part of the 90s. The Serbian soldiers that committed mass murder of Bosnian population, mostly men, referred to this as "ethnic cleansing" which sounded better than "genocide"

Answer: Development
Explanation: The human and natural resources in a developed area or country are brought to their full potential and to the benefit of the people who are citizens or residents there.
Development can be measured economically by the Gross Domestic Product GDP and by its effect on people through the Human Development Index HDI. While GDP measures the total goods and services produced, the HDI measures the level of education and opportunities available to people in the area or country.
Population distribution and density patterns can be useful to understand because they help to explain how and why people migrate and develop in certain places around the world. These factors influence human migration and development and are therefore important to understand if you seek to understand how the world has developed over time and what are the forces that are driving this development.
