In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Einstein created a way of thinking called a?, Context: It was only the orbit of the planet Mercury that Newton's Law of Gravitation seemed not to fully explain. Some astrophysicists predicted the existence of another planet (Vulcan) that would explain the discrepancies; however, despite some early indications, no such planet could be found. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.
[EX A]: theory

[EX Q]: How are the rural medical centers using the highly useful technology of videoconferencing?, Context: Videoconferencing is a highly useful technology for real-time telemedicine and telenursing applications, such as diagnosis, consulting, transmission of medical images, etc... With videoconferencing, patients may contact nurses and physicians in emergency or routine situations; physicians and other paramedical professionals can discuss cases across large distances. Rural areas can use this technology for diagnostic purposes, thus saving lives and making more efficient use of health care money. For example, a rural medical center in Ohio, United States, used videoconferencing to successfully cut the number of transfers of sick infants to a hospital 70 miles (110 km) away. This had previously cost nearly $10,000 per transfer.
[EX A]: cut the number of transfers of sick infants to a hospital

[EX Q]: In the Estonian language, how is the research institute referred to?, Context: The Estonian Academy of Sciences is the national academy of science. The strongest public non-profit research institute that carries out fundamental and applied research is the National Institute of Chemical Physics and Biophysics (NICPB; Estonian KBFI). The first computer centres were established in the late 1950s in Tartu and Tallinn. Estonian specialists contributed in the development of software engineering standards for ministries of the Soviet Union during the 1980s. As of 2011[update], Estonia spends around 2.38% of its GDP on Research and Development, compared to an EU average of around 2.0%.
