Article: Greek figural mosaics could have been copied or adapted paintings, a far more prestigious artform, and the style was enthusiastically adopted by the Romans so that large floor mosaics enriched the floors of Hellenistic villas and Roman dwellings from Britain to Dura-Europos. Most recorded names of Roman mosaic workers are Greek, suggesting they dominated high quality work across the empire; no doubt most ordinary craftsmen were slaves. Splendid mosaic floors are found in Roman villas across North Africa, in places such as Carthage, and can still be seen in the extensive collection in Bardo Museum in Tunis, Tunisia.

Question: What common artform is far more prestigious than mosaic?
Ans: paintings

Here is a question about this article: Islanders speak both English and a creole language known as Norfuk, a blend of 18th-century English and Tahitian. The Norfuk language is decreasing in popularity as more tourists travel to the island and more young people leave for work and study reasons; however, there are efforts to keep it alive via dictionaries and the renaming of some tourist attractions to their Norfuk equivalents. In 2004 an act of the Norfolk Island Assembly made it a co-official language of the island. The act is long-titled: "An Act to recognise the Norfolk Island Language (Norf'k) as an official language of Norfolk Island." The "language known as 'Norf'k'" is described as the language "that is spoken by descendants of the first free settlers of Norfolk Island who were descendants of the settlers of Pitcairn Island". The act recognises and protects use of the language but does not require it; in official use, it must be accompanied by an accurate translation into English. 32% of the total population reported speaking a language other than English in the 2011 census, and just under three-quarters of the ordinarily resident population could speak Norfuk.
What is the answer to this question: The Norfuk language of Norfolk Island was first spoken by whom?
****
So... descendants of the first free settlers of Norfolk Island who were descendants of the settlers of Pitcairn Island

Antibiotics are screened for any negative effects on humans or other mammals before approval for clinical use, and are usually considered safe and most are well tolerated. However, some antibiotics have been associated with a range of adverse side effects. Side-effects range from mild to very serious depending on the antibiotics used, the microbial organisms targeted, and the individual patient. Side effects may reflect the pharmacological or toxicological properties of the antibiotic or may involve hypersensitivity reactions or anaphylaxis. Safety profiles of newer drugs are often not as well established as for those that have a long history of use. Adverse effects range from fever and nausea to major allergic reactions, including photodermatitis and anaphylaxis. Common side-effects include diarrhea, resulting from disruption of the species composition in the intestinal flora, resulting, for example, in overgrowth of pathogenic bacteria, such as Clostridium difficile. Antibacterials can also affect the vaginal flora, and may lead to overgrowth of yeast species of the genus Candida in the vulvo-vaginal area. Additional side-effects can result from interaction with other drugs, such as elevated risk of tendon damage from administration of a quinolone antibiotic with a systemic corticosteroid. Some scientists have hypothesized that the indiscriminate use of antibiotics alter the host microbiota and this has been associated with chronic disease.
Name some adverse effects?
****
The answer: fever and nausea to major allergic reactions, including photodermatitis and anaphylaxis

Problem: Please answer a question about the following article about Light-emitting diode:
The vast majority of devices containing LEDs are "safe under all conditions of normal use", and so are classified as "Class 1 LED product"/"LED Klasse 1". At present, only a few LEDsextremely bright LEDs that also have a tightly focused viewing angle of 8 or lesscould, in theory, cause temporary blindness, and so are classified as "Class 2". The opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) of 2010, on the health issues concerning LEDs, suggested banning public use of lamps which were in the moderate Risk Group 2, especially those with a high blue component in places frequented by children. In general, laser safety regulationsand the "Class 1", "Class 2", etc. systemalso apply to LEDs.
What class are extremely bright LEDs listed as?
A: Class 2

Between the 5th and 8th centuries, new peoples and individuals filled the political void left by Roman centralised government. The Ostrogoths settled in Italy in the late 5th century under Theoderic (d. 526) and set up a kingdom marked by its co-operation between the Italians and the Ostrogoths, at least until the last years of Theodoric's reign. The Burgundians settled in Gaul, and after an earlier realm was destroyed by the Huns in 436 formed a new kingdom in the 440s. Between today's Geneva and Lyon, it grew to become the realm of Burgundy in the late 5th and early 6th centuries. In northern Gaul, the Franks and Britons set up small polities. The Frankish Kingdom was centred in north-eastern Gaul, and the first king of whom much is known is Childeric (d. 481).[G] Under Childeric's son Clovis (r. 509511), the Frankish kingdom expanded and converted to Christianity. Britons, related to the natives of Britannia modern-day Great Britain settled in what is now Brittany.[H] Other monarchies were established by the Visigoths in Iberia, the Suevi in north-western Iberia, and the Vandals in North Africa. In the 6th century, the Lombards settled in northern Italy, replacing the Ostrogothic kingdom with a grouping of duchies that occasionally selected a king to rule over them all. By the late 6th century this arrangement had been replaced by a permanent monarchy.

Who was the first notable king of the Franks?
Answer: Childeric

Since the early history of the United States, Amerindians, AfricanAmericans, and European Americans have been classified as belonging to different races. Efforts to track mixing between groups led to a proliferation of categories, such as mulatto and octoroon. The criteria for membership in these races diverged in the late 19th century. During Reconstruction, increasing numbers of Americans began to consider anyone with "one drop" of known "Black blood" to be Black, regardless of appearance.3 By the early 20th century, this notion was made statutory in many states.4 Amerindians continue to be defined by a certain percentage of "Indian blood" (called blood quantum). To be White one had to have perceived "pure" White ancestry. The one-drop rule or hypodescent rule refers to the convention of defining a person as racially black if he or she has any known African ancestry. This rule meant that those that were mixed race but with some discernible African ancestry were defined as black. The one-drop rule is specific to not only those with African ancestry but to the United States, making it a particularly African-American experience.
When did the criteria for membership in mixed race groups diverge?
in the late 19th century
