Article: The risk of reactivation increases with immunosuppression, such as that caused by infection with HIV. In people coinfected with M. tuberculosis and HIV, the risk of reactivation increases to 10% per year. Studies using DNA fingerprinting of M. tuberculosis strains have shown reinfection contributes more substantially to recurrent TB than previously thought, with estimates that it might account for more than 50% of reactivated cases in areas where TB is common. The chance of death from a case of tuberculosis is about 4% as of 2008, down from 8% in 1995.

Question: What disease has a similar relationship as TB does between reactivation and immunosuppression?
Ans: HIV

Article: Genes are regulated so that they are expressed only when the product is needed, since expression draws on limited resources.:7 A cell regulates its gene expression depending on its external environment (e.g. available nutrients, temperature and other stresses), its internal environment (e.g. cell division cycle, metabolism, infection status), and its specific role if in a multicellular organism. Gene expression can be regulated at any step: from transcriptional initiation, to RNA processing, to post-translational modification of the protein. The regulation of lactose metabolism genes in E. coli (lac operon) was the first such mechanism to be described in 1961.

Question: What are examples of a cell's external environment?
Ans: available nutrients, temperature and other stresses

Article: While Dutch generally refers to the language as a whole, Belgian varieties are sometimes collectively referred to as Flemish. In both Belgium and the Netherlands, the native official name for Dutch is Nederlands, and its dialects have their own names, e.g. Hollands "Hollandish", West-Vlaams "Western Flemish", Brabants "Brabantian". The use of the word Vlaams ("Flemish") to describe Standard Dutch for the variations prevalent in Flanders and used there, however, is common in the Netherlands and Belgium.

Question: If "Vlaams" is "Flemish," what would English speakers call "West-Vlaams"?
Ans: Western Flemish

Article: In the Treaty of Fontainebleau, the Allies exiled him to Elba, an island of 12,000 inhabitants in the Mediterranean, 20 km (12 mi) off the Tuscan coast. They gave him sovereignty over the island and allowed him to retain the title of Emperor. Napoleon attempted suicide with a pill he had carried after nearly being captured by the Russians during the retreat from Moscow. Its potency had weakened with age, however, and he survived to be exiled while his wife and son took refuge in Austria. In the first few months on Elba he created a small navy and army, developed the iron mines, and issued decrees on modern agricultural methods.

Question: In what sea is Elba located?
Ans:
the Mediterranean
