Problem: A UCLA research study published in the June 2006 issue of the American Journal of Geriatric Psychiatry found that people can improve cognitive function and brain efficiency through simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives. This study examined 17 subjects, (average age 53) with normal memory performance. Eight subjects were asked to follow a "brain healthy" diet, relaxation, physical, and mental exercise (brain teasers and verbal memory training techniques). After 14 days, they showed greater word fluency (not memory) compared to their baseline performance. No long term follow up was conducted, it is therefore unclear if this intervention has lasting effects on memory.
What can a person do to increase their brain efficiency?
The answer is the following: simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction


The Cherokee Nation instigated a 10-year language preservation plan that involved growing new fluent speakers of the Cherokee language from childhood on up through school immersion programs as well as a collaborative community effort to continue to use the language at home. This plan was part of an ambitious goal that in 50 years, 80% or more of the Cherokee people will be fluent in the language. The Cherokee Preservation Foundation has invested $3 million into opening schools, training teachers, and developing curricula for language education, as well as initiating community gatherings where the language can be actively used. There is a Cherokee language immersion school in Tahlequah, Oklahoma that educates students from pre-school through eighth grade. Graduates are fluent speakers of the language. Several universities offer Cherokee as a second language, including the University of Oklahoma and Northeastern State University.
How much has the Cherokee Preservation Foundation spent on schools?
$3 million


Input: Ashkenazi Jews
No evidence has yet been found of a Jewish presence in antiquity in Germany beyond its Roman border, nor in Eastern Europe. In Gaul and Germany itself, with the possible exception of Trier and Cologne, the archeological evidence suggests at most a fleeting presence of very few Jews, primarily itinerant traders or artisans. A substantial Jewish population emerged in northern Gaul by the Middle Ages, but Jewish communities existed in 465 CE in Brittany, in 524 CE in Valence, and in 533 CE in Orleans. Throughout this period and into the early Middle Ages, some Jews assimilated into the dominant Greek and Latin cultures, mostly through conversion to Christianity.[better source needed] King Dagobert I of the Franks expelled the Jews from his Merovingian kingdom in 629. Jews in former Roman territories faced new challenges as harsher anti-Jewish Church rulings were enforced.

In what year did Jewish communities exist in Brittany?
Output: 465 CE


Input: Article: The origins of the szlachta are shrouded in obscurity and mystery and have been the subject of a variety of theories.:207 Traditionally, its members were owners of landed property, often in the form of "manor farms" or so-called folwarks. The nobility negotiated substantial and increasing political and legal privileges for itself throughout its entire history until the decline of the Polish Commonwealth in the late 18th century.

Now answer this question: Around what time was the decline of the polish common wealth.

Output: late 18th century


Article: Burke was born in Dublin, Ireland. His mother Mary née Nagle (c. 1702 – 1770) was a Roman Catholic who hailed from a déclassé County Cork family (and a cousin of Nano Nagle), whereas his father, a successful solicitor, Richard (died 1761), was a member of the Church of Ireland; it remains unclear whether this is the same Richard Burke who converted from Catholicism. The Burke dynasty descends from an Anglo-Norman knight surnamed de Burgh (latinised as de Burgo) who arrived in Ireland in 1185 following Henry II of England's 1171 invasion of Ireland.

Question: What was Burke's mother's maiden name?
Ans: Nagle


Input: Pacific War
Thus, only in 1944 did the U.S. Navy begin to use its 150 submarines to maximum effect: installing effective shipboard radar, replacing commanders deemed lacking in aggression, and fixing the faults in the torpedoes. Japanese commerce protection was "shiftless beyond description,"[nb 14] and convoys were poorly organized and defended compared to Allied ones, a product of flawed IJN doctrine and training – errors concealed by American faults as much as Japanese overconfidence. The number of U.S. submarines patrols (and sinkings) rose steeply: 350 patrols (180 ships sunk) in 1942, 350 (335) in 1943, and 520 (603) in 1944. By 1945, sinkings of Japanese vessels had decreased because so few targets dared to venture out on the high seas. In all, Allied submarines destroyed 1,200 merchant ships – about five million tons of shipping. Most were small cargo-carriers, but 124 were tankers bringing desperately needed oil from the East Indies. Another 320 were passenger ships and troop transports. At critical stages of the Guadalcanal, Saipan, and Leyte campaigns, thousands of Japanese troops were killed or diverted from where they were needed. Over 200 warships were sunk, ranging from many auxiliaries and destroyers to one battleship and no fewer than eight carriers.

How many Japanese ships were sunk in 1942 by United States submarines?
Output:
180
