Article: From the start of the 20th century through the 1970s, the American tuna fishing fleet and tuna canning industry were based in San Diego, "the tuna capital of the world". San Diego's first tuna cannery was founded in 1911, and by the mid-1930s the canneries employed more than 1,000 people. A large fishing fleet supported the canneries, mostly staffed by immigrant fishermen from Japan, and later from the Portuguese Azores and Italy whose influence is still felt in neighborhoods like Little Italy and Point Loma. Due to rising costs and foreign competition, the last of the canneries closed in the early 1980s.

Question: What nickname was San Diego given by the tuna canning industry in the 1970s?
Ans: the tuna capital of the world

Article: Others have rejected that the doctrine of Immaculate Conception exists in Islam, the Quranic account does not confirm the Immaculate Conception exclusively for Mary as in Islam every human child is born pure and immaculate, her sinless birth is thus independent of the Christian docrtrine of original sin as no such doctrine exists in Islam. Moreover, Hannah's prayer in the Quran for her child to remain protected from Satan (Shaytan) was said after it had already been born, not before and expresses a natural concern any righteous parent would have. The Muslim tradition or hadith, which states that the only children born without the "touch of Satan," were Mary and Jesus. should therefore not be taken in isolation from the Quran, and is to be interpreted within the specific context of exonerating Mary and her child from the charges that were made against them and is not a general statement. The specific mention of Mary and Jesus in this hadith may also be taken to represent a class of people, in keeping with the Arabic language and the Quranic verse [O Satan] surely thou shalt have no power over My servants, except such of the erring ones as choose to follow thee (15:42)

Question: Does everyone agree on the credit that should be given for the story of Mary's inception ?
Ans: Others have rejected that the doctrine of Immaculate Conception exists in Islam

Article: Guinea-Bissau is a republic. In the past, the government had been highly centralized. Multi-party governance was not established until mid-1991. The president is the head of state and the prime minister is the head of government. Since 1974, no president has successfully served a full five-year term.

Question: Who is the head of government?
Ans: prime minister

Article: Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. Green laser pointers outputting at 532 nm (563.5 THz) are relatively inexpensive compared to other wavelengths of the same power, and are very popular due to their good beam quality and very high apparent brightness. The most common green lasers use diode pumped solid state (DPSS) technology to create the green light. An infrared laser diode at 808 nm is used to pump a crystal of neodymium-doped yttrium vanadium oxide (Nd:YVO4) or neodymium-doped yttrium aluminium garnet (Nd:YAG) and induces it to emit 281.76 THz (1064 nm). This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus (KTP), whose non-linear properties generate light at a frequency that is twice that of the incident beam (563.5 THz); in this case corresponding to the wavelength of 532 nm ("green"). Other green wavelengths are also available using DPSS technology ranging from 501 nm to 543 nm. Green wavelengths are also available from gas lasers, including the heliumneon laser (543 nm), the Argon-ion laser (514 nm) and the Krypton-ion laser (521 nm and 531 nm), as well as liquid dye lasers. Green lasers have a wide variety of applications, including pointing, illumination, surgery, laser light shows, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons and bird control.

Question: Which color of lasers are widely available to the general public?
Ans:
green
