Problem: The first truth explains the nature of dukkha. Dukkha is commonly translated as "suffering", "anxiety", "unsatisfactoriness", "unease", etc., and it is said to have the following three aspects:
What does the first of the Four Noble Truths explain?
The answer is the following: the nature of dukkha

Problem: Under the direction of recording engineer C. Robert Fine, Mercury Records initiated a minimalist single microphone monaural recording technique in 1951. The first record, a Chicago Symphony Orchestra performance of Pictures at an Exhibition, conducted by Rafael Kubelik, was described as "being in the living presence of the orchestra" by The New York Times music critic. The series of records was then named Mercury Living Presence. In 1955, Mercury began three-channel stereo recordings, still based on the principle of the single microphone. The center (single) microphone was of paramount importance, with the two side mics adding depth and space. Record masters were cut directly from a three-track to two-track mixdown console, with all editing of the master tapes done on the original three-tracks. In 1961, Mercury enhanced this technique with three-microphone stereo recordings using 35 mm magnetic film instead of half-inch tape for recording. The greater thickness and width of 35 mm magnetic film prevented tape layer print-through and pre-echo and gained extended frequency range and transient response. The Mercury Living Presence recordings were remastered to CD in the 1990s by the original producer, Wilma Cozart Fine, using the same method of 3-to-2 mix directly to the master recorder.
In which year did Mercury begin 3 channel stereo recording?
The answer is the following: 1955

Problem: This is the passive, active, and dynamic employment of capabilities to respond to imminent or on-going actions against Air Force or Air Force-protected networks, the Air Force's portion of the Global Information Grid, or expeditionary communications assigned to the Air Force. Cyberspace defense incorporates CNE, computer network defense (CND), and CNA techniques and may be a contributor to influence operations. It is highly dependent upon ISR, fused all-source intelligence, automated indications and warning, sophisticated attribution/characterization, situational awareness, assessment, and responsive C2.
What is one of the things that Cyberspace defense highly dependent on?
The answer is the following: fused all-source intelligence

Problem: Electrochemical migration (ECM) is the growth of conductive metal filaments on or in a printed circuit board (PCB) under the influence of a DC voltage bias. Silver, zinc, and aluminum are known to grow whiskers under the influence of an electric field. Silver also grows conducting surface paths in the presence of halide and other ions, making it a poor choice for electronics use. Tin will grow "whiskers" due to tension in the plated surface. Tin-Lead or solder plating also grows whiskers, only reduced by the percentage Tin replaced. Reflow to melt solder or tin plate to relieve surface stress lowers whisker incidence. Another coating issue is tin pest, the transformation of tin to a powdery allotrope at low temperature.
Along with silver and aluminum, what metal grows metal filaments when exposed to an electric field?
The answer is the following:
zinc
