Problem: Royal Dutch Shell:

In 2010, a leaked cable revealed that Shell claims to have inserted staff into all the main ministries of the Nigerian government and know "everything that was being done in those ministries", according to Shell's top executive in Nigeria. The same executive also boasted that the Nigerian government had forgotten about the extent of Shell's infiltration. Documents released in 2009 (but not used in the court case) reveal that Shell regularly made payments to the Nigerian military in order to prevent protests.

Problem: Estonia:

Estonia is situated in the northern part of the temperate climate zone and in the transition zone between maritime and continental climate. Estonia has four seasons of near-equal length. Average temperatures range from 16.3 C (61.3 F) on the Baltic islands to 18.1 C (64.6 F) inland in July, the warmest month, and from 3.5 C (25.7 F) on the Baltic islands to 7.6 C (18.3 F) inland in February, the coldest month. The average annual temperature in Estonia is 5.2 C (41.4 F). The average precipitation in 19611990 ranged from 535 to 727 mm (21.1 to 28.6 in) per year.

What is the warmest month in Estonia?

Problem: Insect:

The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo 4-stage metamorphosis (see holometabolism). Insects that undergo 3-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the Hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (2228 in). The most diverse insect groups appear to have coevolved with flowering plants.

How does the lifecycle of most insects typically begin?

A: hatch from eggs

Problem: Hanover:

As an important railroad and road junction and production center, Hanover was a major target for strategic bombing during World War II, including the Oil Campaign. Targets included the AFA (Stocken), the Deurag-Nerag refinery (Misburg), the Continental plants (Vahrenwald and Limmer), the United light metal works (VLW) in Ricklingen and Laatzen (today Hanover fairground), the Hanover/Limmer rubber reclamation plant, the Hanomag factory (Linden) and the tank factory M.N.H. Maschinenfabrik Niedersachsen (Badenstedt). Forced labourers were sometimes used from the Hannover-Misburg subcamp of the Neuengamme concentration camp. Residential areas were also targeted, and more than 6,000 civilians were killed by the Allied bombing raids. More than 90% of the city center was destroyed in a total of 88 bombing raids. After the war, the Aegidienkirche was not rebuilt and its ruins were left as a war memorial.
