Answer:
First is the high cost, because it takes a lot of increasingly expensive energy to remove salt from seawater. A second problem is that pumping large volumes of seawater through pipes and using chemicals to sterilize the water and keep down algae growth kills many marine organisms and also requires large inputs of energy (and thus money) to run the pumps. A third problem is that desalination produces huge quantities of salty wastewater that must go somewhere.

The economic crisis in most of the European countries was one of the primary reasons for migration in European countries.
Explanation:
Earlier after the end of second world war, many people migrated from country side to developed countries in search for work, with the intend to get a better life. Many unskilled labors got job in developed countries after this world war.

Answer: 1.9%
Explanation:
First derive the Market return as this is needed in the Capital Asset Pricing Model by using the same model:
Required return = Risk free rate + Beta * ( market return - Risk free rate)
Using stock Y:
12.4% = Risk free rate + 1 * (market return - Risk free rate)
12.4% = Rf + market return - Rf
Market return = 12.4%
Use this to calculate the Risk free rate:
Stock Z:
8.2% = Rf + 0.6 * (12.4% - Rf)
8.2% = Rf + 7.44% - 0.6Rf
Rf - 0.6Rf = 8.2% - 7.44%
0.4Rf = 0.76%
Rf = 0.76% / 0.4
= 1.9%
