Input: Read this: In February 2014, Bloomberg reported that Microsoft would be lowering the price of Windows 8 licenses by 70% for devices that retail under US$250; alongside the announcement that an update to the operating system would allow OEMs to produce devices with as little as 1 GB of RAM and 16 GB of storage, critics felt that these changes would help Windows compete against Linux-based devices in the low-end market, particularly those running Chrome OS. Microsoft had similarly cut the price of Windows XP licenses to compete against the early waves of Linux-based netbooks. Reports also indicated that Microsoft was planning to offer cheaper Windows 8 licenses to OEMs in exchange for setting Internet Explorer's default search engine to Bing. Some media outlets falsely reported that the SKU associated with this plan, "Windows 8.1 with Bing", was a variant which would be a free or low-cost version of Windows 8 for consumers using older versions of Windows. On April 2, 2014, Microsoft ultimately announced that it would be removing license fees entirely for devices with screens smaller than 9 inches, and officially confirmed the rumored "Windows 8.1 with Bing" OEM SKU on May 23, 2014.
Question: When did Windows 8 decrease the price of Windows 8 for devices that cost less than $250?

Output: February 2014

QUES: The cloth or fiber material used, resin material, and the cloth to resin ratio determine the laminate's type designation (FR-4, CEM-1, G-10, etc.) and therefore the characteristics of the laminate produced. Important characteristics are the level to which the laminate is fire retardant, the dielectric constant (er), the loss factor (t), the tensile strength, the shear strength, the glass transition temperature (Tg), and the Z-axis expansion coefficient (how much the thickness changes with temperature).

What's the name for the measurement of a laminate's change in thickness as its temperature changes?
What is the answer?
ANS: Z-axis expansion coefficient

QUES: Timely's first publication, Marvel Comics #1 (cover dated Oct. 1939), included the first appearance of Carl Burgos' android superhero the Human Torch, and the first appearances of Bill Everett's anti-hero Namor the Sub-Mariner, among other features. The issue was a great success, with it and a second printing the following month selling, combined, nearly 900,000 copies. While its contents came from an outside packager, Funnies, Inc., Timely had its own staff in place by the following year. The company's first true editor, writer-artist Joe Simon, teamed with artist and emerging industry notable Jack Kirby to create one of the first patriotically themed superheroes, Captain America, in Captain America Comics #1 (March 1941). It, too, proved a hit, with sales of nearly one million. Goodman formed Timely Comics, Inc., beginning with comics cover-dated April 1941 or Spring 1941.
How many copies did the first printing of Marvel Comics #1 sell?

ANS: unanswerable

The Republic of the Congo also has large untapped base metal, gold, iron and phosphate deposits. The country is a member of the Organization for the Harmonization of Business Law in Africa (OHADA). The Congolese government signed an agreement in 2009 to lease 200,000 hectares of land to South African farmers to reduce its dependence on imports.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What country did the South African government lease land to?
Ah, so.. unanswerable

Question: George VI's coronation took place on 12 May 1937, the date previously intended for Edward's coronation. In a break with tradition, Queen Mary attended the ceremony in a show of support for her son. There was no Durbar held in Delhi for George VI, as had occurred for his father, as the cost would have been a burden to the government of India. Rising Indian nationalism made the welcome that the royal couple would have received likely to be muted at best, and a prolonged absence from Britain would have been undesirable in the tense period before the Second World War. Two overseas tours were undertaken, to France and to North America, both of which promised greater strategic advantages in the event of war.
Try to answer this question if possible: On what date did George VI begin his visit to France?
Answer: unanswerable

Input: Read this: In their attempt to ensure white supremacy decades after emancipation, in the early 20th century, most southern states created laws based on the one-drop rule, defining as black, persons with any known African ancestry. This was a stricter interpretation than what had prevailed in the 19th century; it ignored the many mixed families in the state and went against commonly accepted social rules of judging a person by appearance and association. Some courts called it "the traceable amount rule." Anthropologists called it an example of a hypodescent rule, meaning that racially mixed persons were assigned the status of the socially subordinate group.
Question: What was the rule in the 1800s called?

Output:
the traceable amount rule
