Problem: Please answer a question about the following article about BeiDou Navigation Satellite System:
There are two levels of service provided — a free service to civilians and licensed service to the Chinese government and military. The free civilian service has a 10-meter location-tracking accuracy, synchronizes clocks with an accuracy of 10 nanoseconds, and measures speeds to within 0.2 m/s. The restricted military service has a location accuracy of 10 centimetres, can be used for communication, and will supply information about the system status to the user. To date, the military service has been granted only to the People's Liberation Army and to the Military of Pakistan.
What is something the licensed military service can be used for?
A: communication

Problem: Addition of lead(II) oxide lowers melting point, lowers viscosity of the melt, and increases refractive index. Lead oxide also facilitates solubility of other metal oxides and is used in colored glasses. The viscosity decrease of lead glass melt is very significant (roughly 100 times in comparison with soda glasses); this allows easier removal of bubbles and working at lower temperatures, hence its frequent use as an additive in vitreous enamels and glass solders. The high ionic radius of the Pb2+ ion renders it highly immobile in the matrix and hinders the movement of other ions; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda-lime glass (108.5 vs 106.5 Ohm·cm, DC at 250 °C). For more details, see lead glass.
What makes glass melt at a lower temperature?
The answer is the following: lead(II) oxide


The use of time is an important issue in understanding human behavior, education, and travel behavior. Time-use research is a developing field of study. The question concerns how time is allocated across a number of activities (such as time spent at home, at work, shopping, etc.). Time use changes with technology, as the television or the Internet created new opportunities to use time in different ways. However, some aspects of time use are relatively stable over long periods of time, such as the amount of time spent traveling to work, which despite major changes in transport, has been observed to be about 20–30 minutes one-way for a large number of cities over a long period.
Travelling to work has been observed to be about how long for a large number of cities over a long period?
20–30 minutes one-way


Input: Federal Bureau of Investigation
J. Edgar Hoover served as Director from 1924 to 1972, a combined 48 years with the BOI, DOI, and FBI. He was chiefly responsible for creating the Scientific Crime Detection Laboratory, or the FBI Laboratory, which officially opened in 1932, as part of his work to professionalize investigations by the government. Hoover was substantially involved in most major cases and projects that the FBI handled during his tenure. After Hoover's death, Congress passed legislation that limited the tenure of future FBI Directors to ten years.

Who was Director from 1924 to 1972?
Output: J. Edgar Hoover


Problem: Please answer a question about the following article about Apollo:
Though the proportions were always important in Greek art, the appeal of the Greek sculptures eludes any explanation by proportion alone. The statues of Apollo were thought to incarnate his living presence, and these representations of illusive imaginative reality had deep roots in the Minoan period, and in the beliefs of the first Greek speaking people who entered the region during the bronze-age. Just as the Greeks saw the mountains, forests, sea and rivers as inhabited by concrete beings, so nature in all of its manifestations possesses clear form, and the form of a work of art. Spiritual life is incorporated in matter, when it is given artistic form. Just as in the arts the Greeks sought some reality behind appearances, so in mathematics they sought permanent principles which could be applied wherever the conditions were the same. Artists and sculptors tried to find this ideal order in relation with mathematics, but they believed that this ideal order revealed itself not so much to the dispassionate intellect, as to the whole sentient self. Things as we see them, and as they really are, are one, that each stresses the nature of the other in a single unity.
The statues of who were thought to incarnate his living presence?
A:
Apollo
