[Q]: Question: "Have fewer elevators been installed in the United States or China?" Context: "As of January 2008, Spain is the nation with the most elevators installed in the world, with 950,000 elevators installed that run more than one hundred million lifts every day, followed by United States with 700,000 elevators installed and China with 610,000 elevators installed since 1949. In Brazil, it is estimated that there are approximately 300,000 elevators currently in operation. The world's largest market for elevators is Italy, with more than 1,629 million euros of sales and 1,224 million euros of internal market." Answer:
****
[A]: China

[Q]: Question: "What did William Chambers influence?" Context: "By the mid 18th century, the movement broadened to incorporate a greater range of Classical influences, including those from Ancient Greece. The shift to neoclassical architecture is conventionally dated to the 1750s. It first gained influence in England and France; in England, Sir William Hamilton's excavations at Pompeii and other sites, the influence of the Grand Tour and the work of William Chambers and Robert Adam, was pivotal in this regard. In France, the movement was propelled by a generation of French art students trained in Rome, and was influenced by the writings of Johann Joachim Winckelmann. The style was also adopted by progressive circles in other countries such as Sweden and Russia." Answer:
****
[A]: neoclassical architecture

[Q]: Question: "What would surprise computer gurus of decades ago to see happen now?" Context: "Some computers are designed to distribute their work across several CPUs in a multiprocessing configuration, a technique once employed only in large and powerful machines such as supercomputers, mainframe computers and servers. Multiprocessor and multi-core (multiple CPUs on a single integrated circuit) personal and laptop computers are now widely available, and are being increasingly used in lower-end markets as a result." Answer:
****
[A]: Some computers are designed to distribute their work across several CPUs in a multiprocessing configuration

[Q]: Question: "The MCAT or the SAT in the US are examples of what administered to students?" Context: "The practice of component interface testing can be used to check the handling of data passed between various units, or subsystem components, beyond full integration testing between those units. The data being passed can be considered as "message packets" and the range or data types can be checked, for data generated from one unit, and tested for validity before being passed into another unit. One option for interface testing is to keep a separate log file of data items being passed, often with a timestamp logged to allow analysis of thousands of cases of data passed between units for days or weeks. Tests can include checking the handling of some extreme data values while other interface variables are passed as normal values. Unusual data values in an interface can help explain unexpected performance in the next unit. Component interface testing is a variation of black-box testing, with the focus on the data values beyond just the related actions of a subsystem component." Answer:
****
[A]:
Tests
