Problem: Imperial submitted a total of 1,257 staff across 14 units of assessment to the 2014 Research Excellence Framework (REF) assessment. In the REF results 46% of Imperial's submitted research was classified as 4*, 44% as 3*, 9% as 2* and 1% as 1*, giving an overall GPA of 3.36. In rankings produced by Times Higher Education based upon the REF results Imperial was ranked 2nd overall for GPA and 8th for "research power" (compared to 6th and 7th respectively in the equivalent rankings for the RAE 2008).

Problem: In the late nineteenth century, two black Congressmen were elected from North Carolina's 2nd district, the last in 1898. George Henry White sought to promote civil rights for blacks and to challenge efforts by white Democrats to reduce black voting by new discriminatory laws. They were unsuccessful. In 1900, the state legislature passed a new constitution, with voter registration rules that disfranchised most blacks and many poor whites. The state succeeded in reducing black voting to zero by 1908. Loss of the ability to vote disqualified black men (and later women) from sitting on juries and serving in any office, local, state or federal. The rising black middle-class in Raleigh and other areas was politically silenced and shut out of local governance, and the Republican Party was no longer competitive. It was not until after federal civil rights legislation was passed in the mid-1960s that the majority of blacks in North Carolina would again be able to vote, sit on juries and serve in local offices. No African American was elected to Congress until 1992.
When did blacks lose the right to vote?

Problem: Estonia produces about 75% of its consumed electricity. In 2011 about 85% of it was generated with locally mined oil shale. Alternative energy sources such as wood, peat, and biomass make up approximately 9% of primary energy production. Renewable wind energy was about 6% of total consumption in 2009. Estonia imports petroleum products from western Europe and Russia. Oil shale energy, telecommunications, textiles, chemical products, banking, services, food and fishing, timber, shipbuilding, electronics, and transportation are key sectors of the economy. The ice-free port of Muuga, near Tallinn, is a modern facility featuring good transshipment capability, a high-capacity grain elevator, chill/frozen storage, and new oil tanker off-loading capabilities.[citation needed] The railroad serves as a conduit between the West, Russia, and other points to the East.[citation needed]
What percentage of electricity was produced with local oil shale in 2011?
