Input: Read this: Some species of marine animals exist and rely, directly or indirectly, on the phytoplankton. Antarctic sea life includes penguins, blue whales, orcas, colossal squids and fur seals. The emperor penguin is the only penguin that breeds during the winter in Antarctica, while the Adélie penguin breeds farther south than any other penguin. The rockhopper penguin has distinctive feathers around the eyes, giving the appearance of elaborate eyelashes. King penguins, chinstrap penguins, and gentoo penguins also breed in the Antarctic.
Question: What do the phytolankton depend on?

Output: unanswerable


QUES: Generally, this pattern is a circuit consisting of five "legs" that form a rectangle (two legs and the runway form one side, with the remaining legs forming three more sides). Each leg is named (see diagram), and ATC directs pilots on how to join and leave the circuit. Traffic patterns are flown at one specific altitude, usually 800 or 1,000 ft (244 or 305 m) above ground level (AGL). Standard traffic patterns are left-handed, meaning all turns are made to the left. One of the main reason for this is that pilots sit on the left side of the airplane, and a Left-hand patterns improves their visibility of the airport and pattern. Right-handed patterns do exist, usually because of obstacles such as a mountain, or to reduce noise for local residents. The predetermined circuit helps traffic flow smoothly because all pilots know what to expect, and helps reduce the chance of a mid-air collision.

Traffic patterns are usually flown at what altitude above ground level?
What is the answer?
ANS: 800 or 1,000 ft


QUES: By the late 1990s, blue LEDs became widely available. They have an active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN, called cladding layers. By varying the relative In/Ga fraction in the InGaN quantum wells, the light emission can in theory be varied from violet to amber. Aluminium gallium nitride (AlGaN) of varying Al/Ga fraction can be used to manufacture the cladding and quantum well layers for ultraviolet LEDs, but these devices have not yet reached the level of efficiency and technological maturity of InGaN/GaN blue/green devices. If un-alloyed GaN is used in this case to form the active quantum well layers, the device will emit near-ultraviolet light with a peak wavelength centred around 365 nm. Green LEDs manufactured from the InGaN/GaN system are far more efficient and brighter than green LEDs produced with non-nitride material systems, but practical devices still exhibit efficiency too low for high-brightness applications.[citation needed]
What are cladding layers?

ANS: active region consisting of one or more InGaN quantum wells sandwiched between thicker layers of GaN


In 530 BC Cyrus the Great, King of the Persian Achaemenid Empire crossed the Hindu-Kush mountains to seek tribute from the tribes of Kamboja, Gandhara and the trans-India region (modern Afghanistan and Pakistan). By 520 BC, during the reign of Darius I of Persia, much of the northwestern subcontinent (present-day eastern Afghanistan and Pakistan) came under the rule of the Persian Achaemenid Empire, as part of the far easternmost territories. The area remained under Persian control for two centuries. During this time India supplied mercenaries to the Persian army then fighting in Greece.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): By 520 BC what empire ruled the northwestern Indian subcontinent?
Ah, so.. Persian Achaemenid Empire


Question: On March 23, 2011, the CRTC rejected an application by the CBC to install a digital transmitter serving Fredricton, New Brunswick in place of the analogue transmitter serving Fredericton and Saint John, New Brunswick, which would have served only 62.5% of the population served by the existing analogue transmitter. The CBC issued a press release stating "CBC/Radio-Canada intends to re-file its application with the CRTC to provide more detailed cost estimates that will allow the Commission to better understand the unfeasibility of replicating the Corporation’s current analogue coverage." The press release further added that the CBC suggests coverage could be maintained if the CRTC were to "allow CBC Television to continue providing the analogue service it offers today – much in the same way the Commission permitted recently in the case of Yellowknife, Whitehorse and Iqaluit."
Try to answer this question if possible: What did CBC say would allow broadcasting to continue?
Answer: if the CRTC were to "allow CBC Television to continue providing the analogue service it offers today


Input: Read this: The 9/11 Commission's final report on July 22, 2004 stated that the FBI and Central Intelligence Agency (CIA) were both partially to blame for not pursuing intelligence reports that could have prevented the September 11, 2001 attacks. In its most damning assessment, the report concluded that the country had "not been well served" by either agency and listed numerous recommendations for changes within the FBI. While the FBI has acceded to most of the recommendations, including oversight by the new Director of National Intelligence, some former members of the 9/11 Commission publicly criticized the FBI in October 2005, claiming it was resisting any meaningful changes.
Question: What agencies were to blame for 9/11?

Output:
FBI and Central Intelligence Agency
