Problem: Karl Popper:

Instead, he formulated the spearhead model of evolution, a version of genetic pluralism. According to this model, living organisms themselves have goals, and act according to these goals, each guided by a central control. In its most sophisticated form, this is the brain of humans, but controls also exist in much less sophisticated ways for species of lower complexity, such as the amoeba. This control organ plays a special role in evolution—it is the "spearhead of evolution". The goals bring the purpose into the world. Mutations in the genes that determine the structure of the control may then cause drastic changes in behaviour, preferences and goals, without having an impact on the organism's phenotype. Popper postulates that such purely behavioural changes are less likely to be lethal for the organism compared to drastic changes of the phenotype.

What is a species of higher complexity than the human brain?

A: unanswerable


Problem: In addition to the above, Greece is also to start oil and gas exploration in other locations in the Ionian Sea, as well as the Libyan Sea, within the Greek exclusive economic zone, south of Crete. The Ministry of the Environment, Energy and Climate Change announced that there was interest from various countries (including Norway and the United States) in exploration, and the first results regarding the amount of oil and gas in these locations were expected in the summer of 2012. In November 2012, a report published by Deutsche Bank estimated the value of natural gas reserves south of Crete at €427 billion.
What is Greece set to start exploring the Ionian Sea for?

Answer: oil and gas


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Articles 46–53 of the Vienna Convention on the Law of Treaties set out the only ways that treaties can be invalidated—considered unenforceable and void under international law. A treaty will be invalidated due to either the circumstances by which a state party joined the treaty, or due to the content of the treaty itself. Invalidation is separate from withdrawal, suspension, or termination (addressed above), which all involve an alteration in the consent of the parties of a previously valid treaty rather than the invalidation of that consent in the first place.
Which processes simply alter the consent given by parties to a previously valid treaty rather than invalidating the consent completely?
A: withdrawal, suspension, or termination


Context and question: Utrecht is the centre of a densely populated area, which makes concise definitions of its agglomeration difficult, and somewhat arbitrary. The smaller Utrecht agglomeration of continuously built up areas counts some 420,000 inhabitants and includes Nieuwegein, IJsselstein and Maarssen. It is sometimes argued that the close by municipalities De Bilt, Zeist, Houten, Vianen, Driebergen-Rijsenburg (Utrechtse Heuvelrug), and Bunnik should also be counted towards the Utrecht agglomeration, bringing the total to 640,000 inhabitants. The larger region, including slightly more remote towns such as Woerden and Amersfoort counts up to 820,000 inhabitants.
More populated areas include 
Answer: The larger region, including slightly more remote towns such as Woerden and Amersfoort counts up to 820,000 inhabitants


Question: Himachal is extremely rich in hydro electric resources. The state has about 25% of the national potential in this respect. It has been estimated that about 20,300MW of hydro electric power can be generated in the State by constructing various major, medium, small and mini/micro hydel projects on the five river basins. The state is also the first state in India to achieve the goal of having a bank account for every family.[citation needed] As per the current prices, the total GDP was estimated at ₹ 254 billion as against ₹ 230 billion in the year 2004–05, showing an increase of 10.5%. The recent years witnessed quick establishment of International Entrepreneurship. Luxury hotels, food and franchisees of recognised brands e.g. Mc Donalds, KFC and Pizza hut have rapidly spread.
Is there an answer to this question: How much hydroelectric power can be generated?

Answer: 20,300MW


Problem: Liberia:

On April 12, 1980, a military coup led by Master Sergeant Samuel Doe of the Krahn ethnic group overthrew and killed President William R. Tolbert, Jr..
