input question: Question: "What can be said of what rain can cause problematically?"  Context: "Houston has mild winters in contrast to most areas of the United States. In January, the normal mean temperature at Intercontinental Airport is 53.1 °F (11.7 °C), while that station has an average of 13 days with a low at or below freezing. Snowfall is rare. Recent snow events in Houston include a storm on December 24, 2004 when one inch (2.5 cm) of snow accumulated in parts of the metro area. Falls of at least one inch on both December 10, 2008 and December 4, 2009 marked the first time measurable snowfall had occurred in two consecutive years in the city's recorded history. The coldest temperature officially recorded in Houston was 5 °F (−15 °C) on January 18, 1940. Houston has historically received an ample amount of rainfall, averaging about 49.8 in (1,260 mm) annually per 1981–2010 normals. Localized flooding often occurs, owing to the extremely flat topography and widespread typical clay-silt prairie soils, which do not drain quickly."  Answer:???
output answer: Localized flooding often occurs, owing to the extremely flat topography and widespread typical clay-silt prairie soils, which do not drain quickly

Question: "what is the last group mentioned?"  Context: "On 6 August 1940, Estonia was annexed by the Soviet Union as the Estonian SSR. The provisions in the Estonian constitution requiring a popular referendum to decide on joining a supra-national body were ignored. Instead the vote to join the Soviet Union was taken by those elected in the elections held the previous month. Additionally those who had failed to do their "political duty" of voting Estonia into the USSR, specifically those who had failed to have their passports stamped for voting, were condemned to death by Soviet tribunals. The repressions followed with the mass deportations carried out by the Soviets in Estonia on 14 June 1941. Many of the country's political and intellectual leaders were killed or deported to remote areas of the USSR by the Soviet authorities in 1940–1941. Repressive actions were also taken against thousands of ordinary people."  Answer:
----
Answer: thousands of ordinary people

Q: Question: "What is shown by the hypothesis?"  Context: "Recent molecular phylogenetic studies suggest that most placental orders diverged about 100 to 85 million years ago and that modern families appeared in the period from the late Eocene through the Miocene. But paleontologists object that no placental fossils have been found from before the end of the Cretaceous. The earliest undisputed fossils of placentals come from the early Paleocene, after the extinction of the dinosaurs. In particular, scientists have recently identified an early Paleocene animal named Protungulatum donnae as one of the first placental mammals. The earliest known ancestor of primates is Archicebus achilles from around 55 million years ago. This tiny primate weighed 20–30 grams (0.7–1.1 ounce) and could fit within a human palm."  Answer:
A: most placental orders diverged about 100 to 85 million years ago

Question: Question: "Where were the militias involved in quelling the Arab revolt of 1936-1939 from?"  Context: "The Third (1919–23) and Fourth Aliyahs (1924–29) brought an additional 100,000 Jews to Palestine. Finally, the rise of Nazism and the increasing persecution of Jews in 1930s Europe led to the Fifth Aliyah, with an influx of a quarter of a million Jews. This was a major cause of the Arab revolt of 1936–39 during which the British Mandate authorities alongside the Zionist militias of Haganah and Irgun killed 5,032 Arabs and wounded 14,760, resulting in over ten percent of the adult male Palestinian Arab population killed, wounded, imprisoned or exiled. The British introduced restrictions on Jewish immigration to Palestine with the White Paper of 1939. With countries around the world turning away Jewish refugees fleeing the Holocaust, a clandestine movement known as Aliyah Bet was organized to bring Jews to Palestine. By the end of World War II, the Jewish population of Palestine had increased to 33% of the total population. On July 22, 1946, Irgun attacked the British administrative headquarters for Palestine, which was housed in the southern wing of the King David Hotel in Jerusalem. 91 people of various nationalities were killed and 46 were injured. The hotel was the site of the central offices of the British Mandatory authorities of Palestine, principally the Secretariat of the Government of Palestine and the Headquarters of the British Armed Forces in Palestine and Transjordan. The attack initially had the approval of the Haganah (the principal Jewish paramilitary group in Palestine). It was conceived as a response to Operation Agatha (a series of widespread raids, including one on the Jewish Agency, conducted by the British authorities) and was the deadliest directed at the British during the Mandate era (1920–1948)."  Answer:
Answer: Haganah and Irgun

[Q]: Question: "what is the third word in the first paragraph ?"  Context: "Stepper motors are a type of motor frequently used when precise rotations are required. In a stepper motor an internal rotor containing PMs or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"—starts and then quickly stops again—from one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down arbitrarily at any time."  Answer:
****
[A]: are

Problem: Given the question: Question: "Which of the following is not a rating on the Fujita scale: F4, F5, or Oklahoma City?"  Context: "Oklahoma City has a very active severe weather season from March through June, especially during April and May. Being in the center of what is colloquially referred to as Tornado Alley, it is prone to especially frequent and severe tornadoes, as well as very severe hailstorms and occasional derechoes. Tornadoes have occurred in every month of the year and a secondary smaller peak also occurs during autumn, especially October. The Oklahoma City metropolitan area is one of the most tornado-prone major cities in the world, with about 150 tornadoes striking within the city limits since 1890. Since the time weather records have been kept, Oklahoma City has been struck by thirteen violent tornadoes, eleven F/EF4s and two F/EF5. On May 3, 1999 parts of southern Oklahoma City and nearby suburban communities suffered from one of the most powerful tornadoes on record, an F5 on the Fujita scale, with wind speeds estimated by radar at 318 mph (510 km/h). On May 20, 2013, far southwest Oklahoma City, along with Newcastle and Moore, was hit again by a EF5 tornado; it was 0.5 to 1.3 miles (0.80 to 2.09 km) wide and killed 23 people. Less than two weeks later, on May 31, another outbreak affected the Oklahoma City area, including an EF1 and an EF0 within the city and a tornado several miles west of the city that was 2.6 miles (4.2 km) in width, the widest tornado ever recorded."  Answer:

The answer is:
Oklahoma City
