Problem: Myocardial infarction:

Thrombolysis involves the administration of medication that activates the enzymes that normally destroy blood clots. Thrombolysis agents include streptokinase, reteplase, alteplase, and tenecteplase. If no contraindications are present (such as a high risk of bleeding), thrombolysis can be given in the pre-hospital or in-hospital setting. When given to people suspected of having a STEMI within 6 hours of the onset of symptoms, thrombolytic drugs save the life of 1 in 43 who received them. The risks were major bleeding (1 in 143) and brain bleeding (1 in 250). It is unclear whether pre-hospital thrombolysis reduces death in people with STEMI compared to in-hospital thrombolysis. Pre-hospital thrombolysis reduces time to thrombolytic treatment, based on studies conducted in higher income countries.

If thrombolytic drugs are given after 6 hours of onset, what are the odds of bleeding?

Problem: Financial crisis of 2007%E2%80%9308:

Market strategist Phil Dow believes distinctions exist "between the current market malaise" and the Great Depression. He says the Dow Jones average's fall of more than 50% over a period of 17 months is similar to a 54.7% fall in the Great Depression, followed by a total drop of 89% over the following 16 months. "It's very troubling if you have a mirror image," said Dow. Floyd Norris, the chief financial correspondent of The New York Times, wrote in a blog entry in March 2009 that the decline has not been a mirror image of the Great Depression, explaining that although the decline amounts were nearly the same at the time, the rates of decline had started much faster in 2007, and that the past year had only ranked eighth among the worst recorded years of percentage drops in the Dow. The past two years ranked third, however.

How much did the Dow Jones average fall during a period of 17 months?

A: 50%

Problem: Slavs:

Throughout their history, Slavs came into contact with non-Slavic groups. In the postulated homeland region (present-day Ukraine), they had contacts with the Iranic Sarmatians and the Germanic Goths. After their subsequent spread, they began assimilating non-Slavic peoples. For example, in the Balkans, there were Paleo-Balkan peoples, such as Romanized and Hellenized (Jirecek Line) Illyrians, Thracians and Dacians, as well as Greeks and Celtic Scordisci. Over time, due to the larger number of Slavs, most descendants of the indigenous populations of the Balkans were Slavicized. The Thracians and Illyrians vanished from the population during this period although the modern Albanian nation claims descent from the Illyrians. Exceptions are Greece, where the lesser numbered Slavs scattered there came to be Hellenized (aided in time by more Greeks returning to Greece in the 9th century and the role of the church and administration) and Romania where Slavic people settled en route for present-day Greece, Republic of Macedonia, Bulgaria and East Thrace whereby the Slavic population had come to assimilate. Bulgars were also assimilated by local Slavs but their ruling status and subsequent land cast the nominal legacy of Bulgarian country and people onto all future generations. The Romance speakers within the fortified Dalmatian cities managed to retain their culture and language for a long time, as Dalmatian Romance was spoken until the high Middle Ages. However, they too were eventually assimilated into the body of Slavs.

When did Dalmatian Romance assimilate the Slavs?

Problem: Germans:

The Nazis, led by Adolf Hitler, attempted to unite all the people they claimed were "Germans" (Volksdeutsche) into one realm, including ethnic Germans in eastern Europe, many of whom had emigrated more than one hundred fifty years before and developed separate cultures in their new lands. This idea was initially welcomed by many ethnic Germans in Sudetenland, Austria, Poland, Danzig and western Lithuania, particularly the Germans from Klaipeda (Memel). The Swiss resisted the idea. They had viewed themselves as a distinctly separate nation since the Peace of Westphalia of 1648.

Who welcomed the idea in area such as Sudetenland and Poland?
---
A:
ethnic Germans
