Problem: Please answer a question about the following article about Pope Paul VI:
Paul VI revolutionized papal elections by ordering that only cardinals below the age of eighty might participate in future conclaves. In Ecclesiae Sanctae, his motu proprio of 6 August 1966, he further invited all bishops to offer their retirement to the pontiff no later than the completion of their 75th year of age. This requirement was extended to all Cardinals of the Catholic Church on 21 November 1970. With these two stipulations, the Pope filled several positions with younger bishops and cardinals, and further internationalized the Roman Curia in light of several resignations due to age.
When was Paul Vi's Ecclesiae Sanctae issued?
A: 1966


Question: Read this and answer the question

Apart from its use as a reactant, H
2 has wide applications in physics and engineering. It is used as a shielding gas in welding methods such as atomic hydrogen welding. H2 is used as the rotor coolant in electrical generators at power stations, because it has the highest thermal conductivity of any gas. Liquid H2 is used in cryogenic research, including superconductivity studies. Because H
2 is lighter than air, having a little more than 1⁄14 of the density of air, it was once widely used as a lifting gas in balloons and airships.

Why is it used as the rotor coolant?
Answer: it has the highest thermal conductivity of any gas


Problem: A further complication is that the measurement of γ′p involves the measurement of an electric current: this is invariably measured in conventional amperes rather than in SI amperes, so a conversion factor is required. The symbol Γ′p-90 is used for the measured gyromagnetic ratio using conventional electrical units. In addition, there are two methods of measuring the value, a "low-field" method and a "high-field" method, and the conversion factors are different in the two cases. Only the high-field value Γ′p-90(hi) is of interest in determining the Planck constant.
How do conversion factors compare in "low-field" and "high-field" methods of measuring the gyromagnetic ratio?
The answer is the following: the conversion factors are different in the two cases


Besides increased efficiency of power plants, there was an increase in efficiency (between 1950 and 1973) of the railway utilization of this electricity with energy-intensity dropping from 218 to 124 kwh/10,000 gross tonne-km (of both passenger and freight trains) or a 43% drop. Since energy-intensity is the inverse of energy-efficiency it drops as efficiency goes up. But most of this 43% decrease in energy-intensity also benefited diesel traction. The conversion of wheel bearings from plain to roller, increase of train weight, converting single track lines to double track (or partially double track), and the elimination of obsolete 2-axle freight cars increased the energy-efficiency of all types of traction: electric, diesel, and steam. However, there remained a 12–15% reduction of energy-intensity that only benefited electric traction (and not diesel). This was due to improvements in locomotives, more widespread use of regenerative braking (which in 1989 recycled 2.65% of the electric energy used for traction,) remote control of substations, better handling of the locomotive by the locomotive crew, and improvements in automation. Thus the overall efficiency of electric traction as compared to diesel more than doubled between 1950 and the mid-1970s in the Soviet Union. But after 1974 (thru 1980) there was no improvement in energy-intensity (wh/tonne-km) in part due to increasing speeds of passenger and freight trains.
Elimination of what helped the efficiency of diesel traction to go up?
2-axle freight cars


Input: Montana
Montana is home to the Rocky Mountain Elk Foundation and has a historic big game hunting tradition. There are fall bow and general hunting seasons for elk, pronghorn antelope, whitetail deer and mule deer. A random draw grants a limited number of permits for moose, mountain goats and bighorn sheep. There is a spring hunting season for black bear and in most years, limited hunting of bison that leave Yellowstone National Park is allowed. Current law allows both hunting and trapping of a specific number of wolves and mountain lions. Trapping of assorted fur bearing animals is allowed in certain seasons and many opportunities exist for migratory waterfowl and upland bird hunting.

What season is black bear hunting allowed?
Output: spring


Problem: Please answer a question about the following article about Insect:
Most insects, except some species of cave crickets, are able to perceive light and dark. Many species have acute vision capable of detecting minute movements. The eyes may include simple eyes or ocelli as well as compound eyes of varying sizes. Many species are able to detect light in the infrared, ultraviolet and the visible light wavelengths. Color vision has been demonstrated in many species and phylogenetic analysis suggests that UV-green-blue trichromacy existed from at least the Devonian period between 416 and 359 million years ago.
Most insects have what kind of vision?
A:
acute
