Input: Read this: In boundary scan testing, test circuits integrated into various ICs on the board form temporary connections between the PCB traces to test that the ICs are mounted correctly. Boundary scan testing requires that all the ICs to be tested use a standard test configuration procedure, the most common one being the Joint Test Action Group (JTAG) standard. The JTAG test architecture provides a means to test interconnects between integrated circuits on a board without using physical test probes. JTAG tool vendors provide various types of stimulus and sophisticated algorithms, not only to detect the failing nets, but also to isolate the faults to specific nets, devices, and pins.
Question: What would you avoid by using the Joint Test Action Group standard?

Output: physical test probes


QUES: Predators are often another organism's prey, and likewise prey are often predators. Though blue jays prey on insects, they may in turn be prey for cats and snakes, and snakes may be the prey of hawks. One way of classifying predators is by trophic level. Organisms that feed on autotrophs, the producers of the trophic pyramid, are known as herbivores or primary consumers; those that feed on heterotrophs such as animals are known as secondary consumers. Secondary consumers are a type of carnivore, but there are also tertiary consumers eating these carnivores, quartary consumers eating them, and so forth. Because only a fraction of energy is passed on to the next level, this hierarchy of predation must end somewhere, and very seldom goes higher than five or six levels, and may go only as high as three trophic levels (for example, a lion that preys upon large herbivores such as wildebeest, which in turn eat grasses). A predator at the top of any food chain (that is, one that is preyed upon by no organism) is called an apex predator; examples include the orca, sperm whale, anaconda, Komodo dragon, tiger, lion, tiger shark, Nile crocodile, and most eagles and owls—and even omnivorous humans and grizzly bears. An apex predator in one environment may not retain this position as a top predator if introduced to another habitat, such as a dog among alligators, a skunk in the presence of the great horned owl immune to skunk spray, or a snapping turtle among jaguars; a predatory species introduced into an area where it faces no predators, such as a domestic cat or a dog in some insular environments, can become an apex predator by default.

What limits the size of a trophic pyramid? 
What is the answer?
ANS: energy


QUES: The impact of the post-election reforms has been observed in numerous areas, including ASEAN's approval of Myanmar's bid for the position of ASEAN chair in 2014; the visit by United States Secretary of State Hillary Clinton in December 2011 for the encouragement of further progress—it was the first visit by a Secretary of State in more than fifty years (Clinton met with the Burmese president and former military commander Thein Sein, as well as opposition leader Aung San Suu Kyi); and the participation of Aung San Suu Kyi's National League for Democracy (NLD) party in the 2012 by-elections, facilitated by the government's abolition of the laws that previously barred the NLD. As of July 2013, about 100 political prisoners remain imprisoned, while conflict between the Burmese Army and local insurgent groups continues.
How long was the interval between the visits from the United States Secretary of State officials ?

ANS: more than fifty years


Burke put forward that "We fear God, we look up with awe to kings; with affection to parliaments; with duty to magistrates; with reverence to priests; and with respect to nobility. Why? Because when such ideas are brought before our minds, it is natural to be so affected". Burke defended this prejudice on the grounds that it is "the general bank and capital of nations, and of ages" and superior to individual reason, which is small in comparison. "Prejudice", Burke claimed, "is of ready application in the emergency; it previously engages the mind in a steady course of wisdom and virtue, and does not leave the man hesitating in the moment of decision, skeptical, puzzled, and unresolved. Prejudice renders a man's virtue his habit". Burke criticised social contract theory by claiming that society is indeed, a contract, but "a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who did Burke say looks to us with reverence?
Ah, so.. unanswerable


Question: In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states. Parameters are chosen such that the "off" output is limited to leakage currents too small to affect connected circuitry; the resistance of the transistor in the "on" state is too small to affect circuitry; and the transition between the two states is fast enough not to have a detrimental effect.
Try to answer this question if possible: How are parameters chosen in a switching circuit?
Answer: the "off" output is limited to leakage currents too small to affect connected circuitry


Problem: In 2008, State Council established a counterpart support plan (《汶川地震灾后恢复重建对口支援方案》). The plan is to arrange 19 eastern and central province and municipalitie to help 18 counties, on "one province to one affected county" basis. The plan spanned 3 years, and cost no less than one percent of the province or municipality's budget.
What did the State Council establish in 2008?
---
Answer:
a counterpart support plan
