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.
According to sources, the most probable answer to this query is that poor delivery service if not well executed can have various effects on the social, economic and environmental problems. Such as increasing the cost value and reducing efficiency (economic), reduce consumer (social) and increase waste (environmental) production.Thank you for your question.

<h2>Answer: D. Rayleigh wave
</h2>
Rayleigh waves are a type of surface acoustic wave that causes particles on the surface of solids to travel along an elliptical path in the vertical plane that contains the direction of wave propagation.
These waves include longitudinal (P wave) and transverse (S wave) movements whose amplitude decreases exponentially as the distance from the surface increases.
This means Rayleigh waves are generated by the interference between the P and S waves on the surface of the Earth.
Canada has the 10th (nominal) or 15th-largest (PPP) economy in the world (measured in US dollars at market exchange rates), is one of the world's wealthiest nations, and is a member of the Organization for Economic Co-operation and Development (OECD) andGroup of Seven (G7). As with other developed nations, the Canadian economy is dominated by the service industry, which employs about three quarters of Canadians.[17] Canada is unusual among developed countries in the importance of the primary sector, with the logging and oil industries being two of Canada's most important. Canada also has a sizable manufacturing sector, based in Central Canada, with the automobile industryand aircraft industry being especially important. With a long coastline, Canada has the 8th largest commercial fishing and seafood industry in the world.[18][19]Canada is one of the global leaders of the entertainment software industry.[20]
