Article: The Gregorian calendar improves the approximation made by the Julian calendar by skipping three Julian leap days in every 400 years, giving an average year of 365.2425 mean solar days long. This approximation has an error of about one day per 3,300 years with respect to the mean tropical year. However, because of the precession of the equinoxes, the error with respect to the vernal equinox (which occurs, on average, 365.24237 days apart near 2000) is 1 day every 7,700 years, assuming a constant time interval between vernal equinoxes, which is not true. By any criterion, the Gregorian calendar is substantially more accurate than the 1 day in 128 years error of the Julian calendar (average year 365.25 days).

Question: The Gregorian calendar is an improvement over what other calendar?
Ans: Julian

Here is a question about this article: The Most Excellent Order of the British Empire is the "order of chivalry of British constitutional monarchy", rewarding contributions to the arts and sciences, work with charitable and welfare organisations and public service outside the Civil Service. It was established on 4 June 1917 by King George V, and comprises five classes, in civil and military divisions, the most senior two of which make the recipient either a knight if male, or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order.
What is the answer to this question: Who established the chivalry of british constiutional monarchy?
****
So... King George V

The problem: Answer a question about this article:
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.
If a statute is unconstitutional, how is it removed?
****
The answer: deleted by a subsequent statute

USB 2.0 devices use a special protocol during reset, called chirping, to negotiate the high bandwidth mode with the host/hub. A device that is HS capable first connects as an FS device (D+ pulled high), but upon receiving a USB RESET (both D+ and D driven LOW by host for 10 to 20 ms) it pulls the D line high, known as chirp K. This indicates to the host that the device is high bandwidth. If the host/hub is also HS capable, it chirps (returns alternating J and K states on D and D+ lines) letting the device know that the hub operates at high bandwidth. The device has to receive at least three sets of KJ chirps before it changes to high bandwidth terminations and begins high bandwidth signaling. Because USB 3.0 uses wiring separate and additional to that used by USB 2.0 and USB 1.x, such bandwidth negotiation is not required.

What type of protocol is used for USB 2.0 devices during a reset?
Answer: a special protocol

One language, Interlingua, was developed so that the languages of Western civilization would act as its dialects. Drawing from such concepts as the international scientific vocabulary and Standard Average European, linguists[who?] developed a theory that the modern Western languages were actually dialects of a hidden or latent language.[citation needed] Researchers at the International Auxiliary Language Association extracted words and affixes that they considered to be part of Interlingua's vocabulary. In theory, speakers of the Western languages would understand written or spoken Interlingua immediately, without prior study, since their own languages were its dialects. This has often turned out to be true, especially, but not solely, for speakers of the Romance languages and educated speakers of English. Interlingua has also been found to assist in the learning of other languages. In one study, Swedish high school students learning Interlingua were able to translate passages from Spanish, Portuguese, and Italian that students of those languages found too difficult to understand. It should be noted, however, that the vocabulary of Interlingua extends beyond the Western language families.
Along with Standard Average European, from what concept was Interlingua derived?
the international scientific vocabulary
