Article: However, it is important to understand that despite the presence of reception statutes, much of contemporary American common law has diverged significantly from English common law. The reason is that although the courts of the various Commonwealth nations are often influenced by each other's rulings, American courts rarely follow post-Revolution Commonwealth rulings unless there is no American ruling on point, the facts and law at issue are nearly identical, and the reasoning is strongly persuasive.

Question: When would American courts follow post-revolution commonwealth rulings?
Ans: there is no American ruling on point

Here is a question about this article: All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds. These two subdivisions are often given the rank of superorder, although Livezey and Zusi assigned them "cohort" rank. Depending on the taxonomic viewpoint, the number of known living bird species varies anywhere from 9,800 to 10,050.
What is the answer to this question: The two subdivisions of what group include Palaeognathae and Neognathae?
****
So... Aves

The problem: Answer a question about this article:
Parallel to the military developments emerged also a constantly more elaborate chivalric code of conduct for the warrior class. This new-found ethos can be seen as a response to the diminishing military role of the aristocracy, and gradually it became almost entirely detached from its military origin. The spirit of chivalry was given expression through the new (secular) type of chivalric orders; the first of these was the Order of St. George, founded by Charles I of Hungary in 1325, while the best known was probably the English Order of the Garter, founded by Edward III in 1348.
In what year was the Order of the Garter established?
****
The answer: 1348

Problem: Please answer a question about the following article about Database:
In this paper, he described a new system for storing and working with large databases. Instead of records being stored in some sort of linked list of free-form records as in CODASYL, Codd's idea was to use a "table" of fixed-length records, with each table used for a different type of entity. A linked-list system would be very inefficient when storing "sparse" databases where some of the data for any one record could be left empty. The relational model solved this by splitting the data into a series of normalized tables (or relations), with optional elements being moved out of the main table to where they would take up room only if needed. Data may be freely inserted, deleted and edited in these tables, with the DBMS doing whatever maintenance needed to present a table view to the application/user.
What system assists a user in seeing a table?
A: DBMS

Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.

What is the percentage of stoke shift loss in YAG phosphor?
Answer: less than 10%

In Lemon v. Kurtzman, 403 U.S. 602 (1971), the court determined that a Pennsylvania state policy of reimbursing the salaries and related costs of teachers of secular subjects in private religious schools violated the Establishment Clause. The court's decision argued that the separation of church and state could never be absolute: "Our prior holdings do not call for total separation between church and state; total separation is not possible in an absolute sense. Some relationship between government and religious organizations is inevitable," the court wrote. "Judicial caveats against entanglement must recognize that the line of separation, far from being a "wall," is a blurred, indistinct, and variable barrier depending on all the circumstances of a particular relationship."
What did the court's decision argue that the separation of church and state could never be?
absolute
