Problem: Plymouth:

The city is home to 261,546 (mid-2014 est.) people, making it the 30th most populous built-up area in the United Kingdom. It is governed locally by Plymouth City Council and is represented nationally by three MPs. Plymouth's economy remains strongly influenced by shipbuilding and seafaring including ferry links to Brittany (Roscoff and St Malo) and Spain (Santander), but has tended toward a service-based economy since the 1990s. It has the largest operational naval base in Western Europe – HMNB Devonport and is home to Plymouth University.

Problem: One way to decrease stigma may be through the promotion of "TB clubs", where those infected may share experiences and offer support, or through counseling. Some studies have shown TB education programs to be effective in decreasing stigma, and may thus be effective in increasing treatment adherence. Despite this, studies on relationship between reduced stigma and mortality are lacking as of 2010, and similar efforts to decrease stigma surrounding AIDS have been minimally effective. Some have claimed the stigma to be worse than the disease, and healthcare providers may unintentionally reinforce stigma, as those with TB are often perceived as difficult or otherwise undesirable. A greater understanding of the social and cultural dimensions of tuberculosis may also help with stigma reduction.
Who have been performing studies on the relationship between stigma and mortality?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The terms used to define Greekness have varied throughout history but were never limited or completely identified with membership to a Greek state. By Western standards, the term Greeks has traditionally referred to any native speakers of the Greek language, whether Mycenaean, Byzantine or modern Greek. Byzantine Greeks called themselves Romioi and considered themselves the political heirs of Rome, but at least by the 12th century a growing number of those educated, deemed themselves the heirs of ancient Greece as well, although for most of the Greek speakers, "Hellene" still meant pagan. On the eve of the Fall of Constantinople the Last Emperor urged his soldiers to remember that they were the descendants of Greeks and Romans.
 What other cultures do the Romioi clam to not be their birthright
A: unanswerable


Context and question: Communications in Somalia encompasses the communications services and capacity of Somalia. Telecommunications, internet, radio, print, television and postal services in the nation are largely concentrated in the private sector. Several of the telecom firms have begun expanding their activities abroad. The Federal government operates two official radio and television networks, which exist alongside a number of private and foreign stations. Print media in the country is also progressively giving way to news radio stations and online portals, as internet connectivity and access increases. Additionally, the national postal service is slated to be officially relaunched in 2013 after a long absence. In 2012, a National Communications Act was also approved by Cabinet members, which lays the foundation for the establishment of a National Communications regulator in the broadcasting and telecommunications sectors.
What type of media decreases and internet connectivity increases?
Answer: Print media

The largest university in Portugal is the University of Lisbon.

Many minerals provide pigments which have been used in green paints and dyes over the centuries. Pigments, in this case, are minerals which reflect the color green, rather that emitting it through luminescent or phosphorescent qualities. The large number of green pigments makes it impossible to mention them all. Among the more notable green minerals, however is the emerald, which is colored green by trace amounts of chromium and sometimes vanadium. Chromium(III) oxide (Cr2O3), is called chrome green, also called viridian or institutional green when used as a pigment. For many years, the source of amazonite's color was a mystery. Widely thought to have been due to copper because copper compounds often have blue and green colors, the blue-green color is likely to be derived from small quantities of lead and water in the feldspar. Copper is the source of the green color in malachite pigments, chemically known as basic copper(II) carbonate.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the symbol for Copper?
Ah, so..
