1. Assume that at maximum production levels, Japan can produce either 100 CD’s or 50 DVD’s. The U. S. can produce either 90 CD’s or 30 DVD’s. a. Draw the PPF curves for each of these countries producing these two products.
b. Who has the absolute advantage for each product? Why?
c. Calculate the comparative advantage for each country in both CD and DVD production and show your results. Who has the comparative advantage for each product? Why?
2. Now assume that China develops a newer technology that gives them absolute advantage over both Japan and the U. S. in both CD and DVD production.
a. Can the Chinese still benefit from trade with the other two countries? Why or why not?
b. If China committed to specializing in one good over another, would that be economically sound? Why or why not?

If you are talking about typical sand you would find at the beach or in a river bed here on earth, there are some differences. i would say the first biggest difference is in composition and mineral make up. although the moon is largely made of the same materials as earth’s mantle and surface, the moon experiences very little weathering (no liquid water and virtually no atmosphere). “earth” sand is typically composed mostly of quartz grains. this is because quartz is highly resistant to both physical and chemical weathering. most of the other minerals originally with the quartz are broken down into fine clay and carried away, chemically eroded/ dissolved, or some combination of the two. this usually leaves only the quartz behind, and so most of the time when you see/think of sand, you are talking about quartz. without these weathering mechanisms on the moon, the “sand” (which is likely more silt or clay sized grains anyways) would consist of mostly other minerals like anorthosite, olivine, and proxene.

Like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
