Problem: Please answer a question about the following article about United States Air Force:
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 nickname is given to Electronic warfare aircraft?
A: The Eye in the Sky
Problem: Please answer a question about the following article about Planck constant:
There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinumiridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems it is known that over such a timescale the many similar PtIr alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
Where is the base unit for the kilogram kept?
A: in a vault just outside Paris
Problem: Please answer a question about the following article about Police:
In Terry v. Ohio (1968) the court divided seizure into two parts, the investigatory stop and arrest. The court further held that during an investigatory stop a police officer's search " [is] confined to what [is] minimally necessary to determine whether [a suspect] is armed, and the intrusion, which [is] made for the sole purpose of protecting himself and others nearby, [is] confined to ascertaining the presence of weapons" (U.S. Supreme Court). Before Terry, every police encounter constituted an arrest, giving the police officer the full range of search authority. Search authority during a Terry stop (investigatory stop) is limited to weapons only.
What is an investigatory stop's search limited to?
A: what [is] minimally necessary to determine whether [a suspect] is armed
Problem: Please answer a question about the following article about Buddhism:
According to Tilmann Vetter, the core of earliest Buddhism is the practice of dhyana. Bronkhorst agrees that dhyana was a Buddhist invention, whereas Norman notes that "the Buddha's way to release [...] was by means of meditative practices." Discriminating insight into transiency as a separate path to liberation was a later development.
Buddha's way to release was by means of what type of practices?
A:
meditative
