Since the canons of criticism are highly susceptible to interpretation, and at times even contradict each other, they may be employed to justify a result that fits the textual critic's aesthetic or theological agenda. Starting in the 19th century, scholars sought more rigorous methods to guide editorial judgment. Best-text editing (a complete rejection of eclecticism) became one extreme. Stemmatics and copy-text editing while both eclectic, in that they permit the editor to select readings from multiple sources sought to reduce subjectivity by establishing one or a few witnesses presumably as being favored by "objective" criteria.[citation needed] The citing of sources used, and alternate readings, and the use of original text and images helps readers and other critics determine to an extent the depth of research of the critic, and to independently verify their work.

Notably, a statute does not disappear automatically merely because it has been found unconstitutional; it must be deleted by a subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis, no sensible lower court will enforce an unconstitutional statute, and any court that does so will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute (where such constitutionality has been expressly established in prior cases) will risk reversal by the Supreme Court.
What is the name of the principle that demands that unconstitutional laws must be removed via subsequent rulings?
A: unanswerable

Believed to be a stowaway on a U.S. military transport near the end of World War II, the brown tree snake (Boiga irregularis) was accidentally introduced to Guam, that previously had no native species of snake. It nearly eliminated the native bird population. The problem was exacerbated because the reptile has no natural predators on the island. The brown tree snake, known locally as the kulebla, is native to northern and eastern coasts of Australia, Papua New Guinea, and the Solomon Islands. While slightly venomous, the snake is relatively harmless to human beings. Although some studies have suggested a high density of these serpents on Guam, residents rarely see the nocturnal creatures. The United States Department of Agriculture has trained detector dogs to keep the snakes out of the island's cargo flow. The United States Geological Survey also has dogs capable of detecting snakes in forested environments around the region's islands.
How many native species of birds did Guam have prior to World War II?
A: unanswerable

By the 1860s the Kingdom of Prussia and the Austrian Empire were the two most powerful nations dominated by German-speaking elites. Both sought to expand their influence and territory. The Austrian Empire like the Holy Roman Empire was a multi-ethnic state, but German-speaking people there did not have an absolute numerical majority; the creation of the Austro-Hungarian Empire was one result of the growing nationalism of other ethnicities especially the Hungarians. Prussia under Otto von Bismarck would ride on the coat-tails of nationalism to unite all of modern-day Germany. The German Empire ("Second Reich") was created in 1871 following the proclamation of Wilhelm I as head of a union of German-speaking states, while disregarding millions of its non-German subjects who desired self-determination from German rule.
What empire was created in the late 18th century?
A:
unanswerable
