Passage: On 21 September, 2015, Canadians Robert Hall and John Ridsdel, as well as Norwegian Kjartan Sekkingstad, and Marites Flor; a Filipino woman, were abducted on Samai island near Davao. Ridsdel was beheaded by Abu Sayyaf on 25 April 2016 following a ransom deadline. ASG reportedly demanded more than $8.1 million for Ridsdel and the others. On 3 May, 2016, a video of the Ridsdel execution was released, along with new demands for the remaining hostages. A masked captor said, "Note to the Philippine government and to the Canadian government: The lesson is clear. John Ridsdel has been beheaded. Now there are three remaining captives here. If you procrastinate once again the negotiations, we will behead this all anytime". On 15 May, Hall appeared in a new video, announcing that he and Norwegian Kjartan Sekkingstad would be decapitated at 3pm on Monday 13 June absent a ransom of $16 million. Both hostages wore orange coveralls, similar to hostages in videos produced by ISIL, to which Abu Sayyaf had previously pledged allegiance. The deadline passed. Hall was beheaded. On 24 June, Abu Sayyaf released Filipina Marites Flor. She was subsequently flown to Davao to meet President-elect Rodrigo Duterte. Duterte said he directed negotiations with the Abu Sayyaf. He did not elaborate. On 17 September, 2016, remaining hostage Norwegian Kjartan Sekkingstad was released on Jolo island. Abu Ramie, an ASG spokesman, claimed $638,000 was paid as ransom.

Passage: Prague employs almost a fifth of the entire Czech workforce, and its wages are significantly above average (~+25%). In December 2015, average salaries available in Prague reached 35,853 CZK, an annual increase of 3.4%, which was nevertheless lower than national increase of 3.9% both in nominal and real terms. (Inflation in Prague was 0.5% in December, compared with 0.1% nationally.) Since 1990, the citys economic structure has shifted from industrial to service-oriented. Industry is present in sectors such as pharmaceuticals, printing, food processing, manufacture of transport equipment, computer technology and electrical engineering. In the service sector, financial and commercial services, trade, restaurants, hospitality and public administration are the most significant. Service (economics) account for around 80 percent of employment. There are 800,000 employees in Prague, including 120,000 commuters. The number of (legally registered) foreign residents in Prague has been increasing in spite of the countrys economic downturn. As of March 2010, 148,035 foreign workers were reported to be living in the city making up about 18 percent of the workforce, up from 131,132 in 2008. Approximately one-fifth of all investment in the Czech Republic takes place in the city.
Question: Which year were there more foreign workers reported living in Prague, 2008 or 2010?

Passage: Melgares's successor, Governor Jose Antonio Vizcarra met Navajo leaders at Paguate on 12 February 1823. His terms essentially stated that the Spanish would settle the Navajo in pueblos and energetically convert them to the Catholic religion. The Navajo were not interested in either of these proposals. They rejected the treaty and renewed the fight. Six New Mexicans were killed at Socorro in April and eight more at Sabinal in May. On 18 June 1823, Vizcarra led 1,500 troops in a 74-day expedition against the Navajo of western New Mexico. His route took him through the Chuska Mountains to the Hopi mesas in what is now Arizona, then north towards Utah, reaching Oljeto Creek in what is now San Juan County, Utah. Thirty-three Navajo were killed, of whom eight were women, and about 30 were captured. The expedition reached Canyon de Chelly in what is now eastern Arizona. In retaliation for Vizcarra's expedition, the Navajo raided Socorro again, and attacked Tome, Albuquerque and reached the outskirts of Santa Fe. The 1823 raid marked the start of a long period of raids and counter raids lasting until 1848 as New Mexicans took Navajo captive to work as slaves, and as Navajo raided to recover their people and to obtain livestock.
Question: When did the Expedition against the Navajo of western Mexico end?
