Problem: Portugal:

Despite the fact that humans have occupied the territory of Portugal for thousands of years, something still remains of the original vegetation. In Geres both deciduous and coniferous forests can be found, an extremely rare worldwide mature mediterranean forest remain in some parts of the Arrabida mountain and a subtropical laurissilva forest, dating back to the Tertiary period, covers its largest continuous area in the world in the Madeira main island. Due to the human population decrease and rural exodus, Pyrenean oak and other local native trees are colonizing many abandoned areas. Boar, Iberian red deer, roe deer, Iberian wild goat, for example, are reported to be expanding greatly, during the last decades. Boars were found recently roaming at night inside large urban areas, like in Setubal. Protected areas of Portugal include one national park (Portuguese: Parque Nacional), 12 natural parks (Portuguese: Parque Natural), nine natural reserves (Portuguese: Reserva Natural), five natural monuments (Portuguese: Monumento Natural), and seven protected landscapes (Portuguese: Paisagem Protegida), which include the Parque Nacional da Peneda-Geres, the Parque Natural da Serra da Estrela and the Paul d'Arzila.

The printed circuit board industry defines heavy copper as layers exceeding three ounces of copper, or approximately 0.0042 inches (4.2 mils, 105 m) thick. PCB designers and fabricators often use heavy copper when design and manufacturing circuit boards in order to increase current-carrying capacity as well as resistance to thermal strains. Heavy copper plated vias transfer heat to external heat sinks. IPC 2152 is a standard for determining current-carrying capacity of printed circuit board traces.
What would a PCB designer use heavy copper to make their circuit board resist?
A: thermal strains

Context and question: Following the purchase of an offshore lease in 2005, Shell initiated its US$4.5 billion Arctic drilling program in 2006, after the corporation purchased the "Kulluk" oil rig and leased the Noble Discoverer drillship. At inception, the project was led by Pete Slaiby, a Shell executive who had previously worked in the North Sea. However, after the purchase of a second offshore lease in 2008, Shell only commenced drilling work in 2012, due to the refurbishment of rigs, permit delays from the relevant authorities and lawsuits. The plans to drill in the Arctic led to protests from environmental groups, particularly Greenpeace; furthermore, analysts in the energy field, as well as related industries, also expressed skepticism due to perceptions that drilling in the region is "too dangerous because of harsh conditions and remote locations".
What caused the delay in drilling after Shell's 2008 purchase?
Answer: the refurbishment of rigs, permit delays from the relevant authorities and lawsuits

In 2008, Forbes magazine named Oklahoma City the most "recession proof city in America". The magazine reported that the city had falling unemployment, one of the strongest housing markets in the country and solid growth in energy, agriculture and manufacturing. However, during the early 1980s, Oklahoma City had one of the worst job and housing markets due to the bankruptcy of Penn Square Bank in 1982 and then the post-1985 crash in oil prices.[citation needed]
What year did forbes list Oklahoma city as "recession proof".
A:
2008
