Problem: Please answer a question about the following article about Aircraft carrier:
On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-WWII Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.
Why do almost all carriers using conventional aircraft have arrested-recovery systems?
A: conventional aircraft cannot decelerate on their own
Problem: Please answer a question about the following article about The Bronx:
The Bronx is named after Jonas Bronck who created the first settlement as part of the New Netherland colony in 1639. The native Lenape were displaced after 1643 by settlers. In the 19th and 20th centuries, the Bronx received many immigrant groups as it was transformed into an urban community, first from various European countries (particularly Ireland, Germany and Italy) and later from the Caribbean region (particularly Puerto Rico, Jamaica and the Dominican Republic), as well as African American migrants from the American South. This cultural mix has made the Bronx a wellspring of both Latin music and hip hop.
When did Bronck settle in the New York area?
A: 1639
Problem: Please answer a question about the following article about Modern history:
Around the end of the 19th century and into the 20th century, the Meiji era was marked by the reign of the Meiji Emperor. During this time, Japan started its modernization and rose to world power status. This era name means "Enlightened Rule". In Japan, the Meiji Restoration started in the 1860s, marking the rapid modernization by the Japanese themselves along European lines. Much research has focused on the issues of discontinuity versus continuity with the previous Tokugawa Period. In the 1960s younger Japanese scholars led by Irokawa Daikichi, reacted against the bureaucratic superstate, and began searching for the historic role of the common people . They avoided the elite, and focused not on political events but on social forces and attitudes. They rejected both Marxism and modernization theory as alien and confining. They stressed the importance of popular energies in the development of modern Japan. They enlarged history by using the methods of social history. It was not until the beginning of the Meiji Era that the Japanese government began taking modernization seriously. Japan expanded its military production base by opening arsenals in various locations. The hyobusho (war office) was replaced with a War Department and a Naval Department. The samurai class suffered great disappointment the following years.
What does "Meija era"
A: Enlightened Rule
Problem: Please answer a question about the following article about Alps:
The Alps are a source of minerals that have been mined for thousands of years. In the 8th to 6th centuries BC during the Hallstatt culture, Celtic tribes mined copper; later the Romans mined gold for coins in the Bad Gastein area. Erzberg in Styria furnishes high-quality iron ore for the steel industry. Crystals are found throughout much of the Alpine region such as cinnabar, amethyst, and quartz. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments.
The cinnabar deposits are found in what area?
A:
Slovenia
