Answer:
Option A will be the appropriate choice.
Explanation:
- The pre-Colombian age encompasses all phase subdivisions throughout American history before the arrival of major European developments on either the American continent, overlapping the duration of the first establishment throughout the Upper Paleolithic era to European colonization mostly during the early medieval century.
- This applies to something like the opportunities ahead of European explorers including colonization arriving.
The other three methods aren't relevant to the particular circumstance. Such that the aforementioned will be the right decision.
650 × 16 = 10400
10400 ÷ 100 = 104
<u>So the answer is 104</u>
Answer: A - P.M. Grootes, K.M. Cuffey, and J.M. Bolzan, among others.
Explanation: Dr. Anandakrishnan collaborated and coauthored with all of the people listed above and has worked with many other people.
During the year 1994, Dr. Sridhar Anandakrishnan collaborated with Kurt M Cuffey, Richard B Alley, Pieter M Grootes and John M Bolzan on the topic 'Calibration of the δ18O isotopic paleothermometer for central Greenland, using borehole temperatures'
They calibrated the δ 18O paleo-thermometer for central Greenland using borehole temperatures, a thermal model forced by a measured δ 18O record and a formal inverse technique. The calibration is determined mostly by temperature fluctuations of the last several centuries, including the Little Ice Age.
Results are generally insensitive to model variables, including initial condition, basal boundary condition, parameterization of snow thermal properties, ice thickness and likely errors in temperature and isotope measurements. Results of this borehole calibration also seem to be in agreement with modern spatial gradients of δ 18O and temperature.
They suggest that calibrations of isotopic paleothermometers using borehole temperatures are a useful paleoclimate tool because they are independent of spatial gradients and include the effects of prehistoric temperatures.
I would have to go with Europe.
