Hi!
The correct options would be B & E.
Rock and granite are hard and tough materials that are allow very minor seepage of water, which is close to negligible which is why these materials have been employed as construction material in buildings.
Clay is relatively more permeable to water as compared to granite and rock, but still does not allow water to flow through easily as it has a low porosity and permeability to water.
Soil & Organic Layer (fertilizer), allow easy passage of water through them due to high porosity.
Hope this helps!
Although I don't know for sure what is an epicycle, I think your answer is right and I would try to explain as apliable to solar systems on the Milky Way known through astronomical discoveries, conside ring just one star called "Sun" and a few distant planets describing a certain type of movement around it. I should add that the Moon describes the same type of movement around the Earth ( which is not a star), being the only natural satelite of the planet Earth, being kept around it by the circumstances created by the proportion of forces occured while moving
Ozone is produced naturally in the stratosphere. But this "good" ozone is gradually being destroyed by man-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These substances were formerly used and sometimes still are used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants. Once released into the air these ozone-depleting substances degrade very slowly. In fact, they can remain intact for years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun's UV rays and release chlorine and bromine molecules, which destroy the "good" ozone. Scientists estimate that one chlorine atom can destroy 100,000 "good" ozone molecules.
Among the northern Andean countries strongly involved in the illegal coca and drug trade, Columbia is now the predominant coca producer, so the answer would be option A.
Hope this helps!
