Problem: After the financial crisis of 2007–08, it was known in 2008–2009 that two Portuguese banks (Banco Português de Negócios (BPN) and Banco Privado Português (BPP)) had been accumulating losses for years due to bad investments, embezzlement and accounting fraud. The case of BPN was particularly serious because of its size, market share, and the political implications - Portugal's then current President, Cavaco Silva, and some of his political allies, maintained personal and business relationships with the bank and its CEO, who was eventually charged and arrested for fraud and other crimes. In the grounds of avoiding a potentially serious financial crisis in the Portuguese economy, the Portuguese government decided to give them a bailout, eventually at a future loss to taxpayers and to the Portuguese people in general.
Which two Portuguese banks had been accumulating losses for years?
The answer is the following: Banco Português de Negócios (BPN) and Banco Privado Português (BPP)

Problem: Three of Europe's major languages are official in Switzerland. Swiss culture is characterised by diversity, which is reflected in a wide range of traditional customs. A region may be in some ways strongly culturally connected to the neighbouring country that shares its language, the country itself being rooted in western European culture. The linguistically isolated Romansh culture in Graubünden in eastern Switzerland constitutes an exception, it survives only in the upper valleys of the Rhine and the Inn and strives to maintain its rare linguistic tradition.
Where is the Romansh culture located?
The answer is the following: in Graubünden in eastern Switzerland

Problem: Tucson was probably first visited by Paleo-Indians, known to have been in southern Arizona about 12,000 years ago. Recent archaeological excavations near the Santa Cruz River have located a village site dating from 2100 BC.[citation needed] The floodplain of the Santa Cruz River was extensively farmed during the Early Agricultural period, circa 1200 BC to AD 150. These people constructed irrigation canals and grew corn, beans, and other crops while gathering wild plants and hunting. The Early Ceramic period occupation of Tucson saw the first extensive use of pottery vessels for cooking and storage. The groups designated as the Hohokam lived in the area from AD 600 to 1450 and are known for their vast irrigation canal systems and their red-on-brown pottery.[citation needed]
When did the Hohokam live in the Tucson area?
The answer is the following:
from AD 600 to 1450
