Problem: In April 1758, the British concluded the Anglo-Prussian Convention with Frederick in which they committed to pay him an annual subsidy of 670,000. Britain also dispatched 9,000 troops to reinforce Ferdinand's Hanoverian army, the first British troop commitment on the continent and a reversal in the policy of Pitt. Ferdinand had succeeded in driving the French from Hanover and Westphalia and re-captured the port of Emden in March 1758 before crossing the Rhine with his own forces, which caused alarm in France. Despite Ferdinand's victory over the French at the Battle of Krefeld and the brief occupation of Dusseldorf, he was compelled by the successful manoeuvering of larger French forces to withdraw across the Rhine.
What was the annual financial commitment by Britain to Frederick?
The answer is the following: an annual subsidy of 670,000

Problem: In the early Western Han, a wealthy salt or iron industrialist, whether a semi-autonomous king or wealthy merchant, could boast funds that rivaled the imperial treasury and amass a peasant workforce of over a thousand. This kept many peasants away from their farms and denied the government a significant portion of its land tax revenue. To eliminate the influence of such private entrepreneurs, Emperor Wu nationalized the salt and iron industries in 117 BC and allowed many of the former industrialists to become officials administering the monopolies. By Eastern Han times, the central government monopolies were repealed in favor of production by commandery and county administrations, as well as private businessmen.
In which year did Emperor Wu monopolize several industries?
The answer is the following: 117 BC

Problem: The purpose of electronic warfare is to deny the opponent an advantage in the EMS and ensure friendly, unimpeded access to the EM spectrum portion of the information environment. Electronic warfare aircraft are used to keep airspaces friendly, and send critical information to anyone who needs it. They are often called "The Eye in the Sky." The roles of the aircraft vary greatly among the different variants to include Electronic Warfare/Jamming (EC-130H), Psychological Operations/Communications (EC-130J), Airborne Early Warning and Control (E-3), Airborne Command Post (E-4B), ground targeting radar (E-8C), range control (E-9A), and communications relay (E-11A)
What is the purpose of electronic warfare?
The answer is the following: deny the opponent an advantage in the EMS

Problem: BYU has designated energy conservation, products and materials, recycling, site planning and building design, student involvement, transportation, water conservation, and zero waste events as top priority categories in which to further its efforts to be an environmentally sustainable campus. The university has stated that "we have a responsibility to be wise stewards of the earth and its resources." BYU is working to increase the energy efficiency of its buildings by installing various speed drives on all pumps and fans, replacing incandescent lighting with fluorescent lighting, retrofitting campus buildings with low-E reflective glass, and upgraded roof insulation to prevent heat loss. The student groups BYU Recycles, Eco-Response, and BYU Earth educate students, faculty, staff, and administrators about how the campus can decrease its environmental impact. BYU Recycles spearheaded the recent campaign to begin recycling plastics, which the university did after a year of student campaigning.
What is BYU working to increase by installing various speed drives on all pumps and fans?
The answer is the following:
energy efficiency of its buildings
