Problem: Every year a "Brotherhood and Unity" relay race is organized in Montenegro, Macedonia and Serbia which ends at the "House of Flowers" in Belgrade on May 25 the final resting place of Tito. At the same time, runners in Slovenia, Croatia and Bosnia and Herzegovina set off for Kumrovec, Tito's birthplace in northern Croatia. The relay is a left-over from Yugoslav times, when young people made a similar yearly trek on foot through Yugoslavia that ended in Belgrade with a massive celebration.
On what day in May does the "Brotherhood and Unity" relay race end?
The answer is the following: 25

The most recognizable icon of Mexico City is the golden Angel of Independence on the wide, elegant avenue Paseo de la Reforma, modeled by the order of the Emperor Maximilian of Mexico after the Champs-Elysees in Paris. This avenue was designed over the Americas' oldest known major roadway in the 19th century to connect the National Palace (seat of government) with the Castle of Chapultepec, the imperial residence. Today, this avenue is an important financial district in which the Mexican Stock Exchange and several corporate headquarters are located. Another important avenue is the Avenida de los Insurgentes, which extends 28.8 km (17.9 mi) and is one of the longest single avenues in the world.
What is the most popular icon of Mexico City?
golden Angel of Independence

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's the common name of polytetrafluoroethylene?
Output: Teflon

Input: Article: The Taragaon Museum presents the modern history of the Kathmandu Valley. It seeks to document 50 years of research and cultural heritage conservation of the Kathmandu Valley, documenting what artists photographers architects anthropologists from abroad had contributed in the second half of the 20th century. The actual structure of the Museum showcases restoration and rehabilitation efforts to preserve the built heritage of Kathmandu. It was designed by Carl Pruscha (master-planner of the Kathmandy Valley ) in 1970 and constructed in 1971. Restoration works began in 2010 to rehabilitate the Taragaon hostel into the Taragaon Museum. The design uses local brick along with modern architectural design elements, as well as the use of circle, triangles and squares. The Museum is within a short walk from the Boudhnath stupa, which itself can be seen from the Museum tower.

Now answer this question: What was the Taragaon Museum prior to being a museum?

Output: hostel

Article: The authors of the study also examined 77 college textbooks in biology and 69 in physical anthropology published between 1932 and 1989. Physical anthropology texts argued that biological races exist until the 1970s, when they began to argue that races do not exist. In contrast, biology textbooks did not undergo such a reversal but many instead dropped their discussion of race altogether. The authors attributed this to biologists trying to avoid discussing the political implications of racial classifications, instead of discussing them, and to the ongoing discussions in biology about the validity of the concept "subspecies". The authors also noted that some widely used textbooks in biology such as Douglas J. Futuyama's 1986 "Evolutionary Biology" had abandoned the race concept, "The concept of race, masking the overwhelming genetic similarity of all peoples and the mosaic patterns of variation that do not correspond to racial divisions, is not only socially dysfunctional but is biologically indefensible as well (pp. 5 18-5 19)." (Lieberman et al. 1992, pp. 31617)

Question: What were biologists trying to avoid discussing the political implications of?
Ans: racial classifications

Input: Bacteria
Carbon metabolism in bacteria is either heterotrophic, where organic carbon compounds are used as carbon sources, or autotrophic, meaning that cellular carbon is obtained by fixing carbon dioxide. Heterotrophic bacteria include parasitic types. Typical autotrophic bacteria are phototrophic cyanobacteria, green sulfur-bacteria and some purple bacteria, but also many chemolithotrophic species, such as nitrifying or sulfur-oxidising bacteria. Energy metabolism of bacteria is either based on phototrophy, the use of light through photosynthesis, or based on chemotrophy, the use of chemical substances for energy, which are mostly oxidised at the expense of oxygen or alternative electron acceptors (aerobic/anaerobic respiration).

Green sulfur-bacteria is typical representative of what type of bacteria?
Output:
autotrophic bacteria
