Problem: Please answer a question about the following article about Asphalt:
The world's largest deposit of natural bitumen, known as the Athabasca oil sands is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies attribute the oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands, to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta bitumen deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage.
Where are the Athabasca oil sands located?
A: Northern Alberta

The U.S. census race definitions says a "black" is a person having origins in any of the black (sub-Saharan) racial groups of Africa. It includes people who indicate their race as "Black, African Am., or Negro" or who provide written entries such as African American, Afro-American, Kenyan, Nigerian, or Haitian. The Census Bureau notes that these classifications are socio-political constructs and should not be interpreted as scientific or anthropological. Most African Americans also have European ancestry in varying amounts; a lesser proportion have some Native American ancestry. For instance, genetic studies of African Americans show an ancestry that is on average 1718% European.

What percentage of African Americans have European ancestry?
Answer: 1718%

Problem: Music was a major part of everyday life.[citation needed] The word itself derives from Greek (mousike), "(art) of the Muses". Many private and public events were accompanied by music, ranging from nightly dining to military parades and manoeuvres. In a discussion of any ancient music, however, non-specialists and even many musicians have to be reminded that much of what makes our modern music familiar to us is the result of developments only within the last 1,000 years; thus, our ideas of melody, scales, harmony, and even the instruments we use may not have been familiar to Romans who made and listened to music many centuries earlier.[citation needed]
What language does the word Music see it's origins in?
The answer is the following: Greek

In dominant-party systems, opposition parties are allowed, and there may be even a deeply established democratic tradition, but other parties are widely considered to have no real chance of gaining power. Sometimes, political, social and economic circumstances, and public opinion are the reason for others parties' failure. Sometimes, typically in countries with less of an established democratic tradition, it is possible the dominant party will remain in power by using patronage and sometimes by voting fraud. In the latter case, the definition between dominant and one-party system becomes rather blurred. Examples of dominant party systems include the People's Action Party in Singapore, the African National Congress in South Africa, the Cambodian People's Party in Cambodia, the Liberal Democratic Party in Japan, and the National Liberation Front in Algeria. One-party dominant system also existed in Mexico with the Institutional Revolutionary Party until the 1990s, in the southern United States with the Democratic Party from the late 19th century until the 1970s, in Indonesia with the Golkar from the early 1970s until 1998.
For how long did the dominant one-party system last in mexico?
1990s

Here is a question about this article: Immunization against the pathogens that cause diarrheal disease is a viable prevention strategy, however it does require targeting certain pathogens for vaccination. In the case of Rotavirus, which was responsible for around 6% of diarrheal episodes and 20% of diarrheal disease deaths in the children of developing countries, use of a Rotavirus vaccine in trials in 1985 yielded a slight (2-3%) decrease in total diarrheal disease incidence, while reducing overall mortality by 6-10%. Similarly, a Cholera vaccine showed a strong reduction in morbidity and mortality, though the overall impact of vaccination was minimal as Cholera is not one of the major causative pathogens of diarrheal disease. Since this time, more effective vaccines have been developed that have the potential to save many thousands of lives in developing nations, while reducing the overall cost of treatment, and the costs to society.
What is the answer to this question: What was the effect of the Rotavirus vaccine?
****
So...
(2-3%) decrease in total diarrheal disease incidence
