Problem: Incandescent light bulb:

In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.

What company invented the tantalum light filament?

A: Siemens

Problem: Downtown San Diego is located on San Diego Bay. Balboa Park encompasses several mesas and canyons to the northeast, surrounded by older, dense urban communities including Hillcrest and North Park. To the east and southeast lie City Heights, the College Area, and Southeast San Diego. To the north lies Mission Valley and Interstate 8. The communities north of the valley and freeway, and south of Marine Corps Air Station Miramar, include Clairemont, Kearny Mesa, Tierrasanta, and Navajo. Stretching north from Miramar are the northern suburbs of Mira Mesa, Scripps Ranch, Rancho Penasquitos, and Rancho Bernardo. The far northeast portion of the city encompasses Lake Hodges and the San Pasqual Valley, which holds an agricultural preserve. Carmel Valley and Del Mar Heights occupy the northwest corner of the city. To their south are Torrey Pines State Reserve and the business center of the Golden Triangle. Further south are the beach and coastal communities of La Jolla, Pacific Beach, Mission Beach, and Ocean Beach. Point Loma occupies the peninsula across San Diego Bay from downtown. The communities of South San Diego, such as San Ysidro and Otay Mesa, are located next to the MexicoUnited States border, and are physically separated from the rest of the city by the cities of National City and Chula Vista. A narrow strip of land at the bottom of San Diego Bay connects these southern neighborhoods with the rest of the city.
What is the only coastal community in San Diego with the word "beach" in its name?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The nation almost immediately fell into civil war that involved various factions fighting one another; these factions were often distinguished by clan loyalties. More than 500,000 residents fled during this time because of persecution, increased poverty and better economic opportunities in the West or in other former Soviet republics. Emomali Rahmon came to power in 1992, defeating former prime minister Abdumalik Abdullajanov in a November presidential election with 58% of the vote. The elections took place shortly after the end of the war, and Tajikistan was in a state of complete devastation. The estimated dead numbered over 100,000. Around 1.2 million people were refugees inside and outside of the country. In 1997, a ceasefire was reached between Rahmon and opposition parties under the guidance of Gerd D. Merrem, Special Representative to the Secretary General, a result widely praised as a successful United Nations peace keeping initiative. The ceasefire guaranteed 30% of ministerial positions would go to the opposition. Elections were held in 1999, though they were criticized by opposition parties and foreign observers as unfair and Rahmon was re-elected with 98% of the vote. Elections in 2006 were again won by Rahmon (with 79% of the vote) and he began his third term in office. Several opposition parties boycotted the 2006 election and the Organization for Security and Cooperation in Europe (OSCE) criticized it, although observers from the Commonwealth of Independent States claimed the elections were legal and transparent. Rahmon's administration came under further criticism from the OSCE in October 2010 for its censorship and repression of the media. The OSCE claimed that the Tajik Government censored Tajik and foreign websites and instituted tax inspections on independent printing houses that led to the cessation of printing activities for a number of independent newspapers.
How were the different factions distinguished from eachother?
A: by clan loyalties

Context and question: In 1996, Marvel had some of its titles participate in "Heroes Reborn", a crossover that allowed Marvel to relaunch some of its flagship characters such as the Avengers and the Fantastic Four, and outsource them to the studios of two of the former Marvel artists turned Image Comics founders, Jim Lee and Rob Liefeld. The relaunched titles, which saw the characters transported to a parallel universe with a history distinct from the mainstream Marvel Universe, were a solid success amidst a generally struggling industry, but Marvel discontinued the experiment after a one-year run and returned the characters to the Marvel Universe proper. In 1998, the company launched the imprint Marvel Knights, taking place within Marvel continuity; helmed by soon-to-become editor-in-chief Joe Quesada, it featured tough, gritty stories showcasing such characters as the Inhumans, Black Panther and Daredevil.
How long did the Image run of Marvel characters last?
Answer: a one-year run

Question: A species can be listed in two ways. The United States Fish and Wildlife Service (FWS) or NOAA Fisheries (also called the National Marine Fisheries Service) can directly list a species through its candidate assessment program, or an individual or organizational petition may request that the FWS or NMFS list a species. A "species" under the act can be a true taxonomic species, a subspecies, or in the case of vertebrates, a "distinct population segment." The procedures are the same for both types except with the person/organization petition, there is a 90-day screening period.
Is there an answer to this question: How many different ways can a species be added to the endangered list?

Answer: two ways

Athanasius is the first person to identify the same 27 books of the New Testament that are in use today. Up until then, various similar lists of works to be read in churches were in use. Athanasius compiled the list to resolve questions about such texts as The Epistle of Barnabas. Athanasius includes the Book of Baruch and the Letter of Jeremiah and places the Book of Esther among the "7 books not in the canon but to be read" along with the Wisdom of Solomon, Sirach (Ecclesiasticus), Judith, Tobit, the Didache, and the Shepherd of Hermas.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who standardized the books of the New Testament?
Ah, so..
Athanasius
