soft clay and wet and sandy soil as they are more likely to collapse or corrode over time especially the wet and sandy soil which will erode with rain or water
Answer:
After reading the statement for answer, I noticed that some were true and some were false. So, I'll assume your question is related to that fact.
Here's an analysis of the statements:
Ancient civilizations once lived along the Nile.
TRUE. That's why we encounter the pyramids in that region.
Fertile lands surround the Nile.
TRUE, since the Nile is THE most important source of water in the area, it's logical for it to be the location of agriculture.
Few people live near the river.
FALSE. In Ancient times and today, the Nile shores host most of the population of Egypt, a large part of the country being essentially a chunk of the Sahara desert.
The Nile provides irrigation for surrounding farms.
TRUE. The Nile is virtually the only source of abundant water in the area.
The Nile runs through Libya and Tunisia.
FALSE. Libya and Tunisia are WEST of the country of Egypt and have nothing to do with the Nile.
So, depending if you had to find the TRUE or FALSE statements in this list, make your pick. I hope that helps.
The answer is: HIGH POROSITY.
________________________________
(although low permeability can be associated with greater water retention. Permeability can be affected by particular size. For instance, larger particular have larger poles, so fluid (water) can pass through water quickly (higher permeability and less water retention). As such, smaller particles have smaller pores, so fluid (water) can pass through water LESS quickly (lower permeability and RETAINING MORE WATER.).

However, "high porosity" is the best choice.
(6x-1) + 121 = 180
6x-1 = 59
6x = 60
x = 10
The drought will affect animals and humans as well as plants in the area causing death in some cases and affects population as well as the food chain
