On 12 December, the Japanese Navy proposed that Guadalcanal be abandoned. At the same time, several army staff officers at the Imperial General Headquarters (IGH) also suggested that further efforts to retake Guadalcanal would be impossible. A delegation, led by IJA Colonel Joichiro Sanada, chief of the IGH's operations section, visited Rabaul on 19 December and consulted Imamura and his staff. Upon the delegation's return to Tokyo, Sanada recommended that Guadalcanal be abandoned. The IGH's top leaders agreed with Sanada's recommendation on 26 December and ordered their staffs to begin drafting plans for a withdrawal from Guadalcanal, establishment of a new defense line in the central Solomons, and a shifting of priorities and resources to the campaign in New Guinea.On 28 December, General Hajime Sugiyama and Admiral Osami Nagano personally informed Emperor Hirohito of the decision to withdraw from Guadalcanal. On 31 December, the Emperor formally endorsed the decision. The Japanese secretly began to prepare for the evacuation, called Operation Ke, scheduled to begin during the latter part of January 1943.

Question: What year did Operation Ke take place?
Answer: 1943
Surprised by the Allied offensive, the Japanese made several attempts between August and November to retake Henderson Field. Three major land battles, seven large naval battles (five nighttime surface actions and two carrier battles), and almost daily aerial battles culminated in the decisive Naval Battle of Guadalcanal in early November, with the defeat of the last Japanese attempt to bombard Henderson Field from the sea and to land with enough troops to retake it. In December, the Japanese abandoned their efforts to retake Guadalcanal, and evacuated their remaining forces by 7 February 1943, in the face of an offensive by the U.S. Army's XIV Corps.

Question: What airfield in Guadalcanal was the focus of intense fighting between Allied & Japanese troops?
Answer: Henderson Field
The 11,000 Marines on Guadalcanal initially concentrated on forming a loose defensive perimeter around Lunga Point and the airfield, moving the landed supplies within the perimeter and finishing the airfield. In four days of intense effort, the supplies were moved from the landing beach into dispersed dumps within the perimeter. Work began on the airfield immediately, mainly using captured Japanese equipment. On 12 August the airfield was named Henderson Field after Lofton R. Henderson, a Marine aviator who was killed during the Battle of Midway. By 18 August the airfield was ready for operation. Five days' worth of food had been landed from the transports, which, along with captured Japanese provisions, gave the Marines a total of 14 days' supply of food. To conserve supplies, the troops were limited to two meals per day.Allied troops encountered a severe strain of dysentery soon after the landings, with one in five Marines afflicted by mid-August. Although some of the Korean construction workers surrendered to the Marines, most of the remaining Japanese and Korean personnel gathered just west of the Lunga perimeter on the west bank of the Matanikau River and subsisted mainly on coconuts. A Japanese naval outpost was also located at Taivu Point, about 35 kilometers (22 mi) east of the Lunga perimeter. On 8 August, a Japanese destroyer from Rabaul delivered 113 naval reinforcement troops to the Matanikau position.

Question: What kind of equipment was used on the airfield?
Answer: captured Japanese equipment
Throughout August, small numbers of U.S. aircraft and their crews continued to arrive at Guadalcanal. By the end of August, 64 aircraft of various types were stationed at Henderson Field. On 3 September, the commander of the 1st Marine Aircraft Wing, U.S. Marine Brigadier General Roy S. Geiger, arrived with his staff and took command of all air operations at Henderson Field. Air battles between the Allied aircraft at Henderson and Japanese bombers and fighters from Rabaul continued almost daily. Between 26 August and 5 September, the U.S. lost about 15 aircraft to the Japanese's approximately 19 aircraft. More than half of the downed U.S. aircrews were rescued while the majority of the Japanese aircrews were never recovered. The eight-hour round-trip flight from Rabaul to Guadalcanal, about 1,120 miles (1,800 km) in total, seriously hampered Japanese efforts to establish air superiority over Henderson Field. Australian coastwatchers on Bougainville and New Georgia islands were often able to provide the Allied forces on Guadalcanal with advance notice of inbound Japanese air strikes, allowing the U.S. fighters time to take off and position themselves to attack the Japanese bombers and fighters as they approached the island. As such, the Japanese air forces were slowly losing a war of attrition in the skies above Guadalcanal.During this time, Vandegrift continued to direct efforts to strengthen and improve the defenses of the Lunga perimeter. Between 21 August and 3 September, he relocated three Marine battalions, including the 1st Raider Battalion, under Merritt A. Edson (Edson's Raiders), and the 1st Parachute Battalion from Tulagi and Gavutu to Guadalcanal. These units added about 1,500 troops to Vandegrift's original 11,000 men defending Henderson Field. The 1st Parachute Battalion, which had suffered heavy casualties in the Battle of Tulagi and Gavutu–Tanambogo in August, was placed under Edson's command.The other relocated battalion, the 1st Battalion, 5th Marine Regiment (1/5), was landed by boat west of the Matanikau near Kokumbuna village on 27 August with the mission of attacking Japanese units in the area, much as in the first Matanikau action of 19 August. In this case the Marines were impeded by difficult terrain, hot sun, and well-emplaced Japanese defenses. The next morning, the Marines found that the Japanese defenders had departed during the night, so the Marines returned to the Lunga perimeter by boat. These actions resulted in the loss of 20 Japanese and 3 Marines.Small Allied naval convoys arrived at Guadalcanal on 23 August, 29 August, 1 September, and 8 September to provide the Marines at Lunga with more food, ammunition, aircraft fuel, aircraft technicians, and other supplies. The convoy on 1 September also brought 392 Seabees to maintain and improve Henderson Field. In addition, on 3 September, Marine Aircraft Group 25 began airlifting high-priority cargo, including personnel, aviation gasoline, munitions, and other supplies, to Henderson Field.

Question: Why did the convoy need to bring 392 Seabees with them?
Answer: to maintain and improve Henderson Field
Throughout the last week of September and the first week of October, Tokyo Express runs delivered troops from the Japanese 2nd Infantry Division to Guadalcanal. The Japanese Navy promised to support the Army's planned offensive not only by delivering the necessary troops, equipment, and supplies to the island, but by stepping up air attacks on Henderson Field and sending warships to bombard the airfield.

Question: What did Tokyo Express run?
Answer: delivered troops from the Japanese 2nd Infantry Division to Guadalcanal.
It is believed that Vietnam Airlines, VASCO's parent company, wants to change the airline into a low-cost model, therefore changing VASCO's operational name to Viet Air. It is also believed that the airline would be serving domestic flights within Vietnam to destinations that are low-yielding as well as competing head on with Jetstar Pacific and VietJet Air. Vietnam Airlines would add more aircraft to VASCO's fleet if the plans are materialized.

Question: if Vasco company change its name, what would it be?
Answer: Viet Air

Hiroshima was the primary target of the first atomic bombing mission on August 6, with Kokura and Nagasaki as alternative targets. The 393d Bombardment Squadron B-29 Enola Gay, named after Tibbets' mother and piloted by Tibbets, took off from North Field, Tinian, about six hours' flight time from Japan. Enola Gay was accompanied by two other B-29s: The Great Artiste, commanded by Major Charles Sweeney, which carried instrumentation, and a then-nameless aircraft later called Necessary Evil, commanded by Captain George Marquardt, which served as the photography aircraft.

Question: When was the atomic bomb dropped on Hiroshima?
Answer: August 6
In contrast to Hiroshima, almost all of the buildings were of old-fashioned Japanese construction, consisting of timber or timber-framed buildings with timber walls (with or without plaster) and tile roofs. Many of the smaller industries and business establishments were also situated in buildings of timber or other materials not designed to withstand explosions. Nagasaki had been permitted to grow for many years without conforming to any definite city zoning plan; residences were erected adjacent to factory buildings and to each other almost as closely as possible throughout the entire industrial valley. On the day of the bombing, an estimated 263,000 people were in Nagasaki, including 240,000 Japanese residents, 10,000 Korean residents, 2,500 conscripted Korean workers, 9,000 Japanese soldiers, 600 conscripted Chinese workers, and 400 Allied prisoners of war in a camp to the north of Nagasaki.

Question: WHat sort of construction were the building mostly made?
Answer: old-fashioned Japanese
The 50,000-watt standard wave station on Saipan, the OWI radio station, broadcast a similar message to Japan every 15 minutes about Hiroshima, stating that more Japanese cities would face a similar fate in the absence of immediate acceptance of the terms of the Potsdam Declaration and emphatically urged civilians to evacuate major cities. Radio Japan, which continued to extoll victory for Japan by never surrendering, had informed the Japanese of the destruction of Hiroshima by a single bomb. Prime Minister Suzuki felt compelled to meet the Japanese press, to whom he reiterated his government's commitment to ignore the Allies' demands and fight on.Soviet Foreign Minister Vyacheslav Molotov informed Tokyo of the Soviet Union's unilateral abrogation of the Soviet–Japanese Neutrality Pact on August 5. At two minutes past midnight on August 9, Tokyo time, Soviet infantry, armor, and air forces had launched the Manchurian Strategic Offensive Operation. Four hours later, word reached Tokyo of the Soviet Union's official declaration of war. The senior leadership of the Japanese Army began preparations to impose martial law on the nation, with the support of Minister of War Korechika Anami, to stop anyone attempting to make peace.On August 7, a day after Hiroshima was destroyed, Dr. Yoshio Nishina and other atomic physicists arrived at the city, and carefully examined the damage. They then went back to Tokyo and told the cabinet that Hiroshima was indeed destroyed by a nuclear weapon. Admiral Soemu Toyoda, the Chief of the Naval General Staff, estimated that no more than one or two additional bombs could be readied, so they decided to endure the remaining attacks, acknowledging "there would be more destruction but the war would go on". American Magic codebreakers intercepted the cabinet's messages.Purnell, Parsons, Tibbets, Spaatz, and LeMay met on Guam that same day to discuss what should be done next. Since there was no indication of Japan surrendering, they decided to proceed with dropping another bomb. Parsons said that Project Alberta would have it ready by August 11, but Tibbets pointed to weather reports indicating poor flying conditions on that day due to a storm, and asked if the bomb could be readied by August 9. Parsons agreed to try to do so.

Question: What was the Solviet Operation that was launched?
Answer: Manchurian Strategic Offensive Operation
The city of Nagasaki had been one of the largest seaports in southern Japan, and was of great wartime importance because of its wide-ranging industrial activity, including the production of ordnance, ships, military equipment, and other war materials. The four largest companies in the city were Mitsubishi Shipyards, Electrical Shipyards, Arms Plant, and Steel and Arms Works, which employed about 90% of the city's labor force, and accounted for 90% of the city's industry. Although an important industrial city, Nagasaki had been spared from firebombing because its geography made it difficult to locate at night with AN/APQ-13 radar.Unlike the other target cities, Nagasaki had not been placed off limits to bombers by the Joint Chiefs of Staff's July 3 directive, and was bombed on a small scale five times. During one of these raids on August 1, a number of conventional high-explosive bombs were dropped on the city. A few hit the shipyards and dock areas in the southwest portion of the city, and several hit the Mitsubishi Steel and Arms Works. By early August, the city was defended by the 134th Anti-Aircraft Regiment of the 4th Anti-Aircraft Division with four batteries of 7 cm (2.8 in) anti-aircraft guns and two searchlight batteries.

Question: What was produced in Nagasaki that made the city strategically important from a military aspect?
Answer: ordnance, ships, military equipment, and other war materials
Many instruments used to perform medieval music still exist in the 21st century, but in different and typically more technologically developed forms. The flute was made of wood in the medieval era rather than silver or other metal, and could be made as a side-blown or end-blown instrument. While modern orchestral flutes are usually made of metal and have complex key mechanisms and airtight pads, medieval flutes had holes that the performer had to cover with the fingers (as with the recorder). The recorder was made of wood during the Medieval era, and despite the fact that in the 2000s, it may be made of synthetic materials, it has more or less retained its past form. The gemshorn is similar to the recorder as it has finger holes on its front, though it is actually a member of the ocarina family. One of the flute's predecessors, the pan flute, was popular in medieval times, and is possibly of Hellenic origin. This instrument's pipes were made of wood, and were graduated in length to produce different pitches.Medieval music used many plucked string instruments like the lute, a fretted instrument with a pear-shaped hollow body which is the predecessor to the modern guitar. Other plucked stringed instruments included the mandore, gittern, citole and psaltery. The dulcimers, similar in structure to the psaltery and zither, were originally plucked, but musicians began to strike the dulcimer with hammers in the 14th century after the arrival of new metal technology that made metal strings possible.The bowed lyra of the Byzantine Empire was the first recorded European bowed string instrument. Like the modern violin, a performer produced sound by moving a bow with tensioned hair over tensioned strings. The Persian geographer Ibn Khurradadhbih of the 9th century (d. 911) cited the Byzantine lyra, in his lexicographical discussion of instruments as a bowed instrument equivalent to the Arab rabāb and typical instrument of the Byzantines along with the urghun (organ), shilyani (probably a type of harp or lyre) and the salandj (probably a bagpipe). The hurdy-gurdy was (and still is) a mechanical violin using a rosined wooden wheel attached to a crank to "bow" its strings. Instruments without sound boxes like the jew's harp were also popular. Early versions of the pipe organ, fiddle (or vielle), and a precursor to the modern trombone (called the sackbut) were used.

Question: What musical instrument could be made with wood and blown side or end ways?
Answer: The flute
NBC momentarily broke into its East Coast feed of The Best of Carson for its bulletin of Lennon's death before returning in the middle of a comedy piece being performed by Johnny Carson. New York rock station WNEW-FM 102.7 immediately suspended all programming and opened its lines to calls from listeners. Stations throughout the country switched to special programming devoted to Lennon and/or Beatles music.The following day, Ono issued a statement: "There is no funeral for John. John loved and prayed for the human race. Please do the same for him. Love, Yoko and Sean."

Question: What is onos' message about John?
Answer: do the same for him
Photographer Annie Leibovitz went to the Lennons' apartment to do a photo shoot for Rolling Stone magazine. Leibovitz promised Lennon that a photo with Ono would make the front cover of the magazine, even though she initially tried to get a picture with Lennon by himself. Leibovitz said, "Nobody wanted [Ono] on the cover". Lennon insisted that both he and his wife be on the cover, and after taking the pictures, Leibovitz left their apartment at 3:30. After the photo shoot, Lennon gave what would be his last interview, to San Francisco DJ Dave Sholin, for a music show to be broadcast on the RKO Radio Network. At 5:40, Lennon and Ono, delayed by a late limousine, left their apartment to mix the song "Walking on Thin Ice" (an Ono song featuring Lennon on lead guitar) at the Record Plant Studio.

Question: at what time did John lennon and Yoko Ono delayed their limousine?
Answer: 5:40
Cortana can integrate with third-party apps on Windows 10 or directly through the service. Starting in late 2016, Cortana integrated with Microsoft's Wunderlist service, allowing Cortana to add and act on reminders.

Question: When was Cortana integraded into microsoft ?
Answer: 2016
Cortana has a "do-not-disturb" mode in which users can specify "quiet hours", as was available for Windows Phone 8.1 users. Users can change the settings so that Cortana calls users by their names or nicknames. It also has a library of "Easter Eggs", pre-determined remarks.When asked for a prediction, Cortana correctly predicted the winners of the first 14 matches of the football 2014 FIFA World Cup knockout stage, including the semi-finals, before it incorrectly picked Brazil over the Netherlands in the third place play-off match; this streak topped Paul the Octopus who correctly predicted all 7 of Germany's 2010 FIFA World Cup matches as well as the Final. Cortana can forecast results in various other sports such as the NBA, the NFL, the Super Bowl, the ICC Cricket World Cup and various European football leagues. Cortana can solve mathematical equations, convert units of measurement, and determine the exchange rates between currencies including Bitcoin.

Question: What is used to determine Bitcoin exchange rates?
Answer: Cortana
Cortana has a built in system of reminders which for example can be associated with a specific contact; it will then remind the user when in communication with that contact, possibly at a specific time or when the phone is in a specific location. Originally these reminders were specific to the device Cortana was installed on, but since Windows 10 Microsoft synchronizes reminders across devices.

Question: What personal assistant is associated with Windows 10?
Answer: Cortana
The development of Cortana started in 2009 in the Microsoft Speech products team with general manager Zig Serafin and Chief Scientist Larry Heck. Heck and Serafin established the vision, mission, and long-range plan for Microsoft's digital-personal-assistant and they built a team with the expertise to create the initial prototypes for Cortana. Some of the key researchers in these early efforts included Microsoft Research researchers Dilek Hakkani-Tür, Gokhan Tur, Andreas Stolcke, and Malcolm Slaney. research software developer Madhu Chinthakunta, and user-experience designer Lisa Stifelman. To develop the Cortana digital assistant, the team interviewed human personal assistants. These interviews inspired a number of unique features in Cortana, including the assistant's "notebook" feature. Originally Cortana was only meant to be a codename, but a petition on Windows Phone's UserVoice site that proved to be popular made the codename official.

Question: What action led to Cortana being the official name?
Answer: a petition
As the Americans converged on Manila from different directions, they found that most of the Imperial Japanese Army troops defending the city had been withdrawn to Baguio City, on the orders of General Tomoyuki Yamashita, commander in chief of Japanese Army forces in the Philippines. Yamashita planned to engage Filipino and U.S. forces in northern Luzon in a co-ordinated campaign, with the aim of buying time for the build-up of defences against the pending Allied invasion of the Japanese home islands. He had three main groups under his command: 80,000 men of the Shimbu Group in the mountains east of Manila, 30,000 of the Kembu Group in the hills north of Manila, and 152,000 in the Shobu Group in northeastern Luzon.General Yamashita did not declare Manila an open city, although General Douglas MacArthur had done so before its capture in 1941. Yamashita had not intended to defend Manila; he did not think that he could feed the city's one million residents and defend a large area with vast tracts of flammable wooden buildings.

Question: Which Japanese army force was led by Tomoyuki Yamashita?
Answer: Japanese Army forces in the Philippines
In a May 2016 conference call to analysts, Lionsgate CEO Jon Feltheimer stated, "We could see doing five or six or seven." On March 22, 2017, Haim Saban said that he and Lionsgate already have a six-film story arc. However, in May 2017, Forbes noted that due to the underwhelming performance of the film in most markets, it was unlikely any sequels would be made. Later that same month, it was reported that the sequels could still be made thanks to record-breaking merchandise sales. Prior to the home release of the movie, Israelite confirmed that talks were taking place regarding a sequel and that he would like to include Lord Zedd in it. The possibility of a sequel increased once more in early July 2017 when it was reported that the film held the number one spot in home media sales and rentals in its first week. In August 2017, Saban abandoned its trademark for the film's logo. A Saban Brands representative stated in October 2017 that "Power Rangers continues to own and renew hundreds of trademark registrations worldwide, including for the 2017 movie logo. The trademark registration process is very nuanced, and the status of the single application has no bearing on our ownership of or the future plans for Power Rangers. The franchise remains as strong and enthusiastic about its future as ever." On May 1, 2018, Saban Brands agreed to sell Power Rangers and other entertainment assets to Hasbro for US$522 million in cash and stock with the sale expect to closed in the second quarter.On August 8, 2018, Hasbro announced they would be working with a film studio to develop a follow-up to Power Rangers. In February 2019, Hasbro CEO Brian Goldner announced in a financial call that Hasbro was in talks with Paramount Pictures to produce the sequel.

Question: When did Haim Saban say he and Lionsgate had an agreement?
Answer: March 22, 2017
