Problem: Estonia:

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 from renewable energy in 2009?
---
A: 6%


Problem: When Pasternak stopped producing Durbin's pictures, and she outgrew her screen persona and pursued more dramatic roles, the studio signed 13-year-old Gloria Jean for her own series of Pasternak musicals from 1939; she went on to star with Bing Crosby, W. C. Fields, and Donald O'Connor. A popular Universal film of the late 1930s was Destry Rides Again (1939), starring James Stewart as Destry and Marlene Dietrich in her comeback role after leaving Paramount Studios.
What woman starred in the 1930 film Destry Rides Again?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Nasser remains an iconic figure in the Arab world, particularly for his strides towards social justice and Arab unity, modernization policies, and anti-imperialist efforts. His presidency also encouraged and coincided with an Egyptian cultural boom, and launched large industrial projects, including the Aswan Dam and Helwan City. Nasser's detractors criticize his authoritarianism, his government's human rights violations, his populist relationship with the citizenry, and his failure to establish civil institutions, blaming his legacy for future dictatorial governance in Egypt. Historians describe Nasser as a towering political figure of the Middle East in the 20th century.
Name two infrastructure projects Nasser spearheaded.
A: Aswan Dam and Helwan City


Context and question: In abstract algebra, more general structures are defined by relaxing some of the axioms defining a group. For example, if the requirement that every element has an inverse is eliminated, the resulting algebraic structure is called a monoid. The natural numbers N (including 0) under addition form a monoid, as do the nonzero integers under multiplication (Z ∖ {0}, ·), see above. There is a general method to formally add inverses to elements to any (abelian) monoid, much the same way as (Q ∖ {0}, ·) is derived from (Z ∖ {0}, ·), known as the Grothendieck group. Groupoids are similar to groups except that the composition a • b need not be defined for all a and b. They arise in the study of more complicated forms of symmetry, often in topological and analytical structures, such as the fundamental groupoid or stacks. Finally, it is possible to generalize any of these concepts by replacing the binary operation with an arbitrary n-ary one (i.e. an operation taking n arguments). With the proper generalization of the group axioms this gives rise to an n-ary group. The table gives a list of several structures generalizing groups.
What can be replaced to simplify abstract algebra concepts?
Answer: the binary operation


Question: Asthma is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate. Asthma may also be classified as atopic (extrinsic) or non-atopic (intrinsic), based on whether symptoms are precipitated by allergens (atopic) or not (non-atopic). While asthma is classified based on severity, at the moment there is no clear method for classifying different subgroups of asthma beyond this system. Finding ways to identify subgroups that respond well to different types of treatments is a current critical goal of asthma research.
Is there an answer to this question: Is there a method for classifying allergen subgroups beyond the existing system?

Answer: unanswerable


Darwin and Wallace unveiled evolution in the late 1850s. There was an immediate rush to bring it into the social sciences. Paul Broca in Paris was in the process of breaking away from the Société de biologie to form the first of the explicitly anthropological societies, the Société d'Anthropologie de Paris, meeting for the first time in Paris in 1859.[n 4] When he read Darwin he became an immediate convert to Transformisme, as the French called evolutionism. His definition now became "the study of the human group, considered as a whole, in its details, and in relation to the rest of nature".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did Broca redefine Transformisme to?
Ah, so..
