Input: Consider Input: Context_1 : The All India Forward Bloc (AIFB) is a left-wing nationalist political party in India. It emerged as a faction within the Indian National Congress in 1939, led by Subhas Chandra Bose. The party re-established as an independent political party after the independence of India. It has its main stronghold in West Bengal. The party's current Secretary-General is Debabrata Biswas. Veteran Indian politicians Sarat Chandra Bose (brother of Subhas Chandra Bose) and Chitta Basu had been the stalwarts of the party in independent India. Context_2 : The Islamic Dawa Party – Iraq Organisation (Arabic: "Ḥizb al Daʿwa al-Islāmiyya - Tanzim al-Iraq") is a political party in Iraq which is a component of the United Iraqi Alliance. It split from the Islamic Dawa Party during the regime of Saddam Hussein when most of the leaders of Dawa were in exile. It was allocated 12 seats by the Alliance after the elections in December 2005. It is led by Hashim Al-Mosawy, who is its Secretary-General. The head of the parliamentary bloc of the party is Kasim Muhammad Taqi al-Sahlani. Context_3 : The Skaff Bloc or Popular Bloc, led by Elias Skaff, was a 5-members bloc (including 1 Armenian Revolutionary Federation member) in the Lebanese Parliament that aligns with the Free Patriotic Movement from 2005 to 2009. It was part of the current Lebanese opposition Change and Reform bloc, headed by Michel Aoun.In 2009 the party lost all his deputy after the victory of the 14 March alliance in the district. Context_4 : Hussein el Moussawi is a Shia Lebanese member of parliament representing the Baalbeck/Hermil district. He is a part of Lebanon's Loyalty to the Resistance bloc in parliament. Context_5 : Ahmad Alhendawi (أحمد الهنداوي) (born 20 May 1984) currently serves as the Secretary-General of the World Organizations of the Scout Movement, the youngest in the history of the organization. Prior to this, he was the first-ever United Nations Secretary-General's Envoy on Youth, appointed by the Secretary-General of the United Nations on January 17, 2013 as the youngest senior official in the history of the United Nations. He supported UN Secretary-General Ban Ki-moon in addressing his thematic priority of working with and for young people as part of his current Five-Year Action Agenda. Context_6 : The Tripoli Bloc has been one of the political blocs present in the Lebanese Parliament. In 1961, the bloc had four members in the parliament. All members of the bloc are deputies from Tripoli (Lebanon). At the elections in June 2005, the bloc was part of the March 14 Alliance and the Rafik Hariri Martyr List that won the elections. It remained committed to the basic premises of the March 14 Alliance in 2008. Context_7 : Nawwaf el Moussawi is a Shia Lebanese member of parliament representing the Sour district. He is part of Hezbollah's bloc. Context_8 : Soyuz (Russian: Союз, translated as 'Union') was a faction in the Congress of People's Deputies of the USSR. The faction was critical of Perestroika and liberal reforms; it was opposed to de-centralization of the Soviet Union. The group was founded on 14 February 1990, and its leaders included Viktor Alksnis (from Latvian SSR), Yegor Ligachev, Nikolai Petrushenko, Yevgeny Kogan (Estonian SSR), and Anatoly Checkoyev (Georgian SSR, South Ossetian autonomous region). The faction claimed to have 500 members in the USSR Supreme Soviet. The group managed to oust Soviet foreign minister Eduard Shevardnadze for 'giving up' Eastern Europe, in February 1991, it asked for a 'state of emergency' to be introduced in the USSR. The Soyuz faction did not formally support the August coup of 1991, an event that had devastating consequences for the faction. Many of the group leaders joined Sergei Baburin's movement Russian All-People's Union and the related Rossiya faction in the RSFSR parliament (sometimes called the sister faction of the Soyuz group). An organization with the same name continued to exist as a political movement in the post-Soviet Russia, featuring communist/Neo-Stalinist views. That organisation took part in the 1995 legislative election within the bloc Power to the People, led by Baburin and Nikolai Ryzhkov. In the 1999 legislative election, the Soyuz movement, then led by Georgy Tikhonov, took part within the Stalin Bloc — For the USSR coalition.

Input: Consider Input: Context_1 : The Ship Canal Bridge is a double-deck steel truss bridge that carries Interstate 5 (I-5) over Seattle's Portage Bay (part of the Lake Washington Ship Canal, after which it is named) between Capitol Hill and the University District. The canal below connects Lake Union with Lake Washington. Construction was completed in 1961 and the bridge opened to traffic on December 18, 1962. It is 4,429 ft (1,350 meters) long, stands 182 feet above the canal and is 119 feet wide at the upper deck. It was the largest bridge of its kind in the Northwest when it first opened. The bridge is double-decked, with the upper deck carrying traffic in both directions and the lower deck (the express lanes) carrying traffic southbound in the morning and northbound in the afternoon. Context_2 : The San Diego Aqueduct, or San Diego Project, is a system of four aqueducts in the U.S. state of California, supplying about 90 percent of the water supply for the city of San Diego. The system comprises the First and Second San Diego Aqueducts, carrying water from the Colorado River west to reservoirs on the outskirts of San Diego. The 70 mi First Aqueduct consists of the pipelines 1 and 2, which run from the Colorado River Aqueduct near San Jacinto, California, to the San Vicente Reservoir, approximately 15 mi northeast of the city. Pipelines 3 and 4 make up the 94 mi Second Aqueduct. Together, these four pipelines have a capacity of 826 ft3/s . The smaller, 12.5 mi Fallbrook-Ocean Branch branches from the First Aqueduct into Morrow Reservoir. The La Mesa-Sweetwater Branch originates from the First Aqueduct, flowing into the Sweetwater Reservoir. Context_3 : The Black River is a tributary of the Duwamish River in King County in the U.S. state of Washington. It drained Lake Washington until 1916, when the opening of the Lake Washington Ship Canal lowered the lake, causing part of the Black River to dry up. It still exists as a dammed stream about 2 mi long. Context_4 : Lake Washington steamboats and ferries operated from about 1875 to 1951, transporting passengers, vehicles and freight across Lake Washington, a large lake to the east of Seattle, Washington. Before modern highways and bridges were built, the only means of crossing the lake, other than the traditional canoe, was by steamboat, and, later, by ferry. While there was no easily navigable connection to Puget Sound, the Lake Washington Ship Canal now connects Lake Washington to Lake Union, and from there Puget Sound is reached by way of the Hiram M. Chittenden Locks. Context_5 : The Lake Washington Ship Canal, which runs through the city of Seattle, connects the fresh water body of Lake Washington with the salt water inland sea of Puget Sound. The Hiram M. Chittenden Locks accommodate the approximately 20 ft difference in water level between Lake Washington and the sound. The canal runs east–west and connects Union Bay, the Montlake Cut, Portage Bay, Lake Union, the Fremont Cut, Salmon Bay, and Shilshole Bay, which is part of the sound. Context_6 : The Fremont Cut is a body of water that forms part of the Lake Washington Ship Canal, which passes through the U.S. city of Seattle and links Lake Washington to Puget Sound. The Fremont Cut connects Lake Union to the east with Salmon Bay to the west. It is 5800 ft long and 270 ft wide. The center channel is 100 ft wide and 30 ft deep. Context_7 : Salmon Bay is a portion of the Lake Washington Ship Canal—a canal which passes through the city of Seattle, linking Lake Washington to Puget Sound—that lies west of the Fremont Cut. It is the westernmost section of the canal, and empties into Puget Sound's Shilshole Bay. Because of the Hiram M. Chittenden Locks, the smaller, western half of the bay is salt water, and the eastern half is fresh water (though not without saline contamination—see Lake Union). Before construction of the Ship Canal, Salmon Bay was entirely salt water. Context_8 : The Conibear Shellhouse is a rowing training and support facility in Seattle, Washington, on the campus of the University of Washington. It is used by the men's and women's rowing teams of the Washington Huskies. The building was completed in 1949 and renovated in 2005. It is located on Lake Washington, near the Lake Washington Ship Canal. Context_9 : Lake Union is a freshwater lake entirely within the Seattle, Washington city limits and a major portion of the Lake Washington Ship Canal. Its easternmost point is the Ship Canal Bridge, which carries Interstate 5 over the eastern arm of the lake and separates Lake Union from Portage Bay. Lake Union is the namesake of the neighborhoods located on its east and west shores: Eastlake and Westlake, respectively. The northern shore of the lake is home to Gas Works Park. Notable features of the southern portion of the lake—collectively known as the South Lake Union district—include Lake Union Park, Museum of History & Industry (MOHAI), and the Center for Wooden Boats. Context_10 : The Colorado River Aqueduct, or CRA, is a 242 mi water conveyance in Southern California in the United States, operated by the Metropolitan Water District of Southern California (MWD). The aqueduct impounds water from the Colorado River at Lake Havasu on the California-Arizona border west across the Mojave and Colorado deserts to the east side of the Santa Ana Mountains. It is one of the primary sources of drinking water for Southern California. fact_1 : The Lake Washington Ship Canal, which runs through the city of Seattle, connects the fresh water body of Lake Washington with the salt water inland sea of Puget Sound. fact_2 : The Colorado River Aqueduct, or CRA, is a 242 mi water conveyance in Southern California in the United States, operated by the Metropolitan Water District of Southern California (MWD). Answer: The Colorado River Aqueduct

Output: Which is longer, the Lake Washington Ship Canal or the Colorado River Aqueduct?


Input: Consider Input: Context_1 : Compounds of nickel are chemical compounds containing the element nickel which is a member of the group 10 of the periodic table. Most compounds in the group have an oxidation state of +2. Nickel is classified as a transition metal with nickel(II) having much chemical behaviour in common with iron(II) and cobalt(II). Many salts of nickel(II) are isomorphous with salts of magnesium due to the ionic radii of the cations being almost the same. Nickel forms many coordination complexes. Nickel tetracarbonyl was the first pure metal carbonyl produced, and is unusual in its volatility. Metalloproteins containing nickel are found in biological systems. Context_2 : A rotary stage is a component of a motion system used to restrict an object to a single axis of rotation. The terms rotary table or rotation stage are often used interchangeably with rotary stage. All rotary stages consist of a platform and a base, joined by some form of guide in such a way that the platform is restricted to rotation about a single axis with respect to the base. In common usage, the term rotary stage may or may not also include the mechanism by which the angular position of the platform is controlled relative to the base. Context_3 : Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Context_4 : In metallurgy, melchior is an alloy of copper, mainly with nickel (5–30%). Its name originates from Italian: "melchior" , which in turn is distorted French: "maillechort" , honoring the French inventors of the alloy, Maillot and Chorier. The term melchior sometimes refers not only to the copper-nickel alloys, but also ternary alloys of copper with nickel and zinc ("nickel silver") and even a silvered brass. Melchior is easily deformable by application of pressure, both in the hot and cold state. After annealing, it has a tensile strength of about 40 kg/mm. The most valuable property of melchior is its high resistance to corrosion in air, freshwater and seawater. Increasing content of nickel iron or manganese improves corrosion and cavitation resistance, especially in sea water and atmospheric water vapor. The alloy of 30% Ni, 0.8% Fe, 1% Mn and 68.2% copper is used in maritime shipping, in particular for the manufacture of condenser tubes. Thanks to the nickel, melchior, unlike brass and bronze, has not a yellow but a silver color. Together with high corrosion resistance, this silvery color is preferred for the manufacture of household utensils. Context_5 : Nickel(II) precatalysts are a type of catalyst used in organic reactions. Many transformations are catalyzed by nickel in organometallic chemistry and in organic synthesis. Many of these transformations invoke a low valent (generally Ni(0)) species as the active catalyst. Unfortunately, unlike its counterpart, Pd(0), Ni(0) catalysts are predominantly confined to the glovebox due to their high instability to air and water, with the most common Ni(0) catalyst being Ni(cod). Additionally, Ni(cod) is more expensive than many Ni(II) salts and the quality varies significantly amongst suppliers. To make nickel catalysis more accessible and amenable to synthesis and industrial purposes, the use of air-stable Ni(II) precursors has emerged as an important development in this area of research. This page describes the more commonly employed nickel(II) precatalysts, their synthesis for those not commercially available, and the methods for their reduction to Ni(0) complexes. Context_6 : A nickel titanium (NiTi) rotary file is an engine-driven tapered and pointed endodontic instrument made of nickel titanium alloy with cutting edges used to mechanically shape and prepare the root canals during endodontic therapy or to remove the root canal obturating material while performing retreatment. The first NiTi file was introduced to the market in 1991. Superelasticity and shape memory are the properties that make Niti files very flexible. The high flexibility of Niti files makes them superior to stainless steel files for the purpose of rotary root canal preparation. The use of NiTi rotary files in dentistry is a common practice. Context_7 : Pulse dialing is a signaling technology in telecommunications in which a direct current local loop circuit is interrupted according to a defined coding system for each signal transmitted, usually a digit. This lends the method the often used name loop disconnect dialing. In the most common variant of pulse dialing, decadic dialing, each of the ten Arabic numerals are encoded in a sequence of up to ten pulses. The most common version decodes the digits 1 through 9, as one to nine pulses, respectively, and the digit 0 as ten pulses. Historically, the most common device to produce such pulse trains is the rotary dial of the telephone, lending the technology another name, rotary dialing. Context_8 : The Leonardo da Vinci Award was established in 1975 by the Rotary Club of Florence as an annual international prize named after Leonardo da Vinci, to be presented to young people involved in the study of the sciences, technology, literature and the arts. Among the disciplines recognised and rewarded so far have been painting, sculpture, music, geology, architecture, medicine and nuclear physics. The 21st Leonardo da Vinci Prize was recently presented to the brilliant young pianist Johan Schmidt. The prize giving event has been hosted by other European Rotary Clubs in cities such as Tours, Vienna, Athens, Madrid, Würzburg, Brussels and Amsterdam. This event was last held in London in 1987, when the prize was awarded to the internationally recognised percussionist Evelyn Glennie. In 1996 1/2 the Rotary Club of London will again be responsible for hosting the prize-giving ceremony. Context_9 : Rotary endodontic files use an engine to rotate the endodontic file during root canal treatment. The advantages of rotary endodontics are reduced instrumentation times and fewer files used during the procedure. Commonly Nickel-Titanium files are used because of their greater flexibility which permits increasingly curved roots to be treated. The use of Ni-ti files comes at a cost of at increased risk of fractured endodontic files, possibly necessitating endodontic retreatment. Context_10 : Rotary Youth Exchange (RYE) is a Rotary International student exchange program for students in secondary school. Since 1929, Rotary International has sent young people around the globe to experience new cultures. Currently, about 9,000 students are sponsored by Rotary clubs every year. Typically, students are sent to another country for a year-long stay, generally living with multiple host families during the year and being expected to perform daily tasks within the household as well as attend school in the host country. Short term exchange programs are also quite common. These typically involve direct student exchanges between two families arranged through Rotary to coincide with major school holiday periods. fact_1 :  Commonly Nickel-Titanium files are used because of their greater flexibility which permits increasingly curved roots to be treated. fact_2 :  Nickel belongs to the transition metals and is hard and ductile. Answer: flexibility


Output: What property does Rotary technology and Nickel have in common?
