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.
<u><em>China financed a large new fleet sent out to trade and build contacts under the command of Zheng He.</em></u>
Answer: Option C
<u>Explanation:</u>
- Ming dynasty is the one and only first Chinese dynasty that showed interest in trading with other countries. Zheng He was a great sea explorer who is also a fleet commander.
- He established trades with many foreign countries. He served under the third Emperor Yongle whose reign was between 1402 to 1424. He built big ships (some families can live in) also named them as Junk to travel in the sea.
- That made the Ming Dynasty earn more money. Ming Dynasty was interested only trading with Portuguese and Spain but most of the Europeans wanted to trade wit Asia for spices and teas.
- When Yongle died the funding for the travel was stopped and that was the end of the Ming Dynasty's International trade through seas.

Venus can come closest to the earth in its orbit and look brightest in our skies.
Venus is extremely bright because it is the nearest planet to Earth and because most of the sunlight that reaches it (about 70%) is reflected back into space by its thick clouds. The brightest object in the sky, Venus is frequently seen within a few hours after sunset or before sunrise.
The Earth and Venus is 38 million kilometres away at the closest point of opposition. This is the planet's closest approach to Earth. Venus has never travelled more than 261 million kilometres from Earth. the fact that the distance between Venus and Earth may change by a staggering 223 million kilometres.

My point of view is if you were living waaayyyyy back then
positive:
- fresh water
- food
- fertile soil
- trading
- easier travel
- can connect cities
negative:
- flooding
- vulnerable to invasions
