Ocean sediment core provides a climate record of the past 70 million years.
1880 is the reliable global record which we can say the climate began. Proxies(climate) helps the scientists to determine the climatic patterns even before starting record-keeping.
Some examples of proxies are sub-fossil pollen, lake and ocean sediments, tree rings, and ice cores. Climatic of the time influenced the growth rate of proxies material. It is from proxies where we can recover quantities of particular isotopes from climatic changes.
The combination of proxies can produce temperature reconstruction which is longer the instrumental temperature.

Answer:
To start a job today that would permit you to earn about 50 percent more than you expected to make after graduation.
Explanation:
Opportunity cost is the cost of best next option foregone for choosing the current option. Here, the best opportunity foregone is of earning and starting the job today which will allow to earn 50 % more than what can be earned after completing the graduation, as already for graduation fees will be paid, along with further expenses. In that case if dropping graduation and starting a job was this beneficial then it would have been better.
Therefore the following has increased the opportunity cost of pursuing graduation.
to start a job today that would permit you to earn about 50 percent more than you expected to make after graduation
Answer:
Ace records the purchase:
Inventory 3,700 Accounts payable 3,700

Answer:
PPF : Downward Sloping Straight Line
Explanation:
PPF is the locus of product combinations that an economy can produce, given resources & technology.
It is downward sloping : Because of inverse relationship between two goods- if one has to be increased other has to be decreased , because of same resources & technology.
Marginal Opportunity Cost (Slope of PPC): is ratio of a good sacrifised to gain each additional unit of the other good.
∆ Good sacrifised / ∆ Good gained
If this ratio is same i.e constant amount of a good is sacrifised to gain an additional amount of the other one , the slope of PPC is constant & it is a straight line
Eg : Good1 Good2 MOC [∆Good2/∆Good1]
0 20 _
10 10 -10/10 = -1 (10-20)/(10-0)
20 0 -10/10 = -1 (0-10)(/20-10)
So , same (1) good 2 is sacrifised to attain a good 1 each time.
However Generally: MOC is increasing , because of assumption that resources are unequally efficient in various goods production - shifting good from efficient to inefficient increases sacrifise each time. This makes PPC usually concave.
