Input: Printed circuit board
There are quite a few different dielectrics that can be chosen to provide different insulating values depending on the requirements of the circuit. Some of these dielectrics are polytetrafluoroethylene (Teflon), FR-4, FR-1, CEM-1 or CEM-3. Well known pre-preg materials used in the PCB industry are FR-2 (phenolic cotton paper), FR-3 (cotton paper and epoxy), FR-4 (woven glass and epoxy), FR-5 (woven glass and epoxy), FR-6 (matte glass and polyester), G-10 (woven glass and epoxy), CEM-1 (cotton paper and epoxy), CEM-2 (cotton paper and epoxy), CEM-3 (non-woven glass and epoxy), CEM-4 (woven glass and epoxy), CEM-5 (woven glass and polyester). Thermal expansion is an important consideration especially with ball grid array (BGA) and naked die technologies, and glass fiber offers the best dimensional stability.

What pre-preg material is designated by "FR-2"?
Output: phenolic cotton paper


Input: Article: Congo-Brazzaville has had a multi-party political system since the early 1990s, although the system is heavily dominated by President Denis Sassou Nguesso; he has lacked serious competition in the presidential elections held under his rule. Sassou Nguesso is backed by his own Congolese Labour Party (French: Parti Congolais du Travail) as well as a range of smaller parties.

Output: Parti Congolais du Travail


Article: In 2010, 6.9% of the population (1,269,765) considered themselves to be of only American ancestry (regardless of race or ethnicity). Many of these were of English or Scotch-Irish descent; however, their families have lived in the state for so long, that they choose to identify as having "American" ancestry or do not know their ancestry. In the 1980 United States census the largest ancestry group reported in Florida was English with 2,232,514 Floridians claiming that they were of English or mostly English American ancestry. Some of their ancestry went back to the original thirteen colonies.

Question: In the 1980 census the largest ancestry group in Florida was 
Ans: largest ancestry group reported in Florida was English with 2,232,514 Floridians claiming that they were of English or mostly English American ancestry


Here is a question about this article: Animals that characterize the Appalachian forests include five species of tree squirrels. The most commonly seen is the low to moderate elevation eastern gray squirrel (Sciurus carolinensis). Occupying similar habitat is the slightly larger fox squirrel (Sciurus niger) and the much smaller southern flying squirrel (Glaucomys volans). More characteristic of cooler northern and high elevation habitat is the red squirrel (Tamiasciurus hudsonicus), whereas the Appalachian northern flying squirrel (Glaucomys sabrinus fuscus), which closely resembles the southern flying squirrel, is confined to northern hardwood and spruce-fir forests.
What is the answer to this question: What is the most commonly seen species?
****
So... gray squirrel


The problem: Answer a question about this article:
Works published since 1857 have received alternative catalogue designations instead of opus numbers. The present standard musicological reference for Chopin's works is the Kobylańska Catalogue (usually represented by the initials 'KK'), named for its compiler, the Polish musicologist Krystyna Kobylańska.
The Kobylańska Catalogue was named for who?
****
The answer: Krystyna Kobylańska


The problem: Answer a question about this article:
Following the fall of Wu and the turmoil of the Wu Hu uprising against the Jin dynasty (265–420), most of elite Chinese families had collaborated with the non-Chinese rulers and military conquerors in the north. Some may have lost social privilege, and took refugee in areas south to Yangtze River. Some of the Chinese refugees from north China might have resided in areas near Hangzhou. For example, the clan of Zhuge Liang (181–234), a chancellor of the state of Shu Han from Central Plain in north China during the Three Kingdoms period, gathered together at the suburb of Hangzhou, forming an exclusive, closed village Zhuge Village (Zhege Cun), consisting of villagers all with family name "Zhuge". The village has intentionally isolated itself from the surrounding communities for centuries to this day, and only recently came to be known in public. It suggests that a small number of powerful, elite Chinese refugees from the Central Plain might have taken refugee in south of the Yangtze River. However, considering the mountainous geography and relative lack of agrarian lands in Zhejiang, most of these refugees might have resided in some areas in south China beyond Zhejiang, where fertile agrarian lands and metropolitan resources were available, mainly north Jiangsu, west Fujian, Jiangxi, Hunan, Anhui,and provinces where less cohesive, organized regional governments had been in place. Metropolitan areas of Sichuan was another hub for refugees, given that the state of Shu had long been founded and ruled by political and military elites from the Central Plain and north China. Some refugees from the north China might have found residence in south China depending on their social status and military power in the north. The rump Jin state or the Southern Dynasties vied against some elite Chinese from the Central Plain and south of the Yangtze River.
When was the Jin Dynasty?
****
The answer:
265–420
