Q: The desert comprises much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and Sudan. It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south, it is bounded by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and the Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions including: the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Air Mountains, the Tenere desert, and the Libyan Desert.
Can we conclude that does the sahara desert stretch across the northern half of africa?

Answer: no
In 1937, Warner introduced its Alphabet Bra with four cup sizes (A, B, C, and D) to its product descriptions. Before long, these cup sizes got nicknames: egg cup, tea cup, coffee cup, and challenge cup, respectively. Two other companies, Model and Fay-Miss (renamed in 1935 as the Bali Brassiere Company), followed, offering A, B, C, and D cup sizes in the late 1930s. Catalog companies continued to use the designations Small, Medium, and Large through the 1940s. Britain did not adopt the American cups in 1933, and resisted using cup sizes for its products until 1948. The Sears Company finally applied cup sizes to bras in its catalog in the 1950s.

Problem: Text: The chemical elements can be broadly divided into metals, metalloids and nonmetals according to their shared physical and chemical properties. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide. Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise extraordinary.

Question: is low conductivity used to tell metals from nonmetals?

- no

IN: Is it true that has anyone ever gone over niagara falls in a barrel?

Numerous objects, both natural and artificial, have gone over the Niagara Falls. These events have been the result of both stunts and accidents, some of which have resulted in fatalities. The first recorded person to survive going over the falls was Annie Edson Taylor, who went over the falls in a barrel in 1901. 72 years previously, however, Sam Patch had jumped from a platform adjacent to Goat Island.

While traveling through the Southern United States in around 1998, Martin McDonagh came across a couple of accusatory billboards about an unsolved crime, which he described as ''raging and painful and tragic (sic)''. The billboards highlighted the incompetence of police work and deeply affected McDonagh; he said that the image ''stayed in my mind (...) kept gnawing at me'' and presumed that they were put up by the victim's mother. This incident, combined with his desire to create strong female characters, inspired him to write the story for Three Billboards Outside Ebbing, Missouri. McDonagh discussed the creative process, saying that it took him about ten years to ''(decide) that it was a mother who had taken these things out. It all became fiction (...) based on a couple of actual billboards''.

OPTIONS:
- no

three billboards outside ebbing missouri is a real story?
