Input: London
London is the world's most expensive office market for the last three years according to world property journal (2015) report. As of 2015[update] the residential property in London is worth $2.2 trillion - same value as that of Brazil annual GDP. The city has the highest property prices of any European city according to the Office for National Statistics and the European Office of Statistics. On average the price per square metre in central London is 24,252 (April 2014). This is higher than the property prices in other G8 European capital cities; Berlin 3,306, Rome 6,188 and Paris 11,229.

What is the average property price per square meter in Berlin as of April 2014?
Output: 3,306

Input: Article: The polarization of an antenna refers to the orientation of the electric field (E-plane) of the radio wave with respect to the Earth's surface and is determined by the physical structure of the antenna and by its orientation; note that this designation is totally distinct from the antenna's directionality. Thus, a simple straight wire antenna will have one polarization when mounted vertically, and a different polarization when mounted horizontally. As a transverse wave, the magnetic field of a radio wave is at right angles to that of the electric field, but by convention, talk of an antenna's "polarization" is understood to refer to the direction of the electric field.

Now answer this question: When is a magnetic fields right angles to a electrical field?

Output: transverse wave

Article: Trading in influence, or influence peddling, refers a person selling his/her influence over the decision making process to benefit a third party (person or institution). The difference with bribery is that this is a tri-lateral relation. From a legal point of view, the role of the third party (who is the target of the influence) does not really matter although he/she can be an accessory in some instances. It can be difficult to make a distinction between this form of corruption and some forms of extreme and loosely regulated lobbying where for instance law- or decision-makers can freely "sell" their vote, decision power or influence to those lobbyists who offer the highest compensation, including where for instance the latter act on behalf of powerful clients such as industrial groups who want to avoid the passing of specific environmental, social, or other regulations perceived as too stringent, etc. Where lobbying is (sufficiently) regulated, it becomes possible to provide for a distinctive criteria and to consider that trading in influence involves the use of "improper influence", as in article 12 of the Criminal Law Convention on Corruption (ETS 173) of the Council of Europe.

Question: Where lobbying is controlled, what does it provide for consideration to determine improper influencing?
Ans: distinctive criteria

Here is a question about this article: The greatest mosaic work of the Palaeologan renaissance in art is the decoration of the Chora Church in Constantinople. Although the mosaics of the naos have not survived except three panels, the decoration of the exonarthex and the esonarthex constitute the most important full-scale mosaic cycle in Constantinople after the Hagia Sophia. They were executed around 1320 by the command of Theodore Metochites. The esonarthex has two fluted domes, specially created to provide the ideal setting for the mosaic images of the ancestors of Christ. The southern one is called the Dome of the Pantokrator while the northern one is the Dome of the Theotokos. The most important panel of the esonarthex depicts Theodore Metochites wearing a huge turban, offering the model of the church to Christ. The walls of both narthexes are decorated with mosaic cycles from the life of the Virgin and the life of Christ. These panels show the influence of the Italian trecento on Byzantine art especially the more natural settings, landscapes, figures.
What is the answer to this question: Who commissioned the mosaics at naos?
****
So... Theodore Metochites

The trip to the Moon took just over three days. After achieving orbit, Armstrong and Aldrin transferred into the Lunar Module, named Eagle, and after a landing gear inspection by Collins remaining in the Command/Service Module Columbia, began their descent. After overcoming several computer overload alarms caused by an antenna switch left in the wrong position, and a slight downrange error, Armstrong took over manual flight control at about 180 meters (590 ft), and guided the Lunar Module to a safe landing spot at 20:18:04 UTC, July 20, 1969 (3:17:04 pm CDT). The first humans on the Moon would wait another six hours before they ventured out of their craft. At 02:56 UTC, July 21 (9:56 pm CDT July 20), Armstrong became the first human to set foot on the Moon.
Who was the first human to take a step on the Moon?
****
The answer: Armstrong

The duplication and transmission of genetic material from one generation of cells to the next is the basis for molecular inheritance, and the link between the classical and molecular pictures of genes. Organisms inherit the characteristics of their parents because the cells of the offspring contain copies of the genes in their parents' cells. In asexually reproducing organisms, the offspring will be a genetic copy or clone of the parent organism. In sexually reproducing organisms, a specialized form of cell division called meiosis produces cells called gametes or germ cells that are haploid, or contain only one copy of each gene.:20.2 The gametes produced by females are called eggs or ova, and those produced by males are called sperm. Two gametes fuse to form a diploid fertilized egg, a single cell that has two sets of genes, with one copy of each gene from the mother and one from the father.:20
In what type of organism will a specialized form of cell division called meiosis produce cells called gametes?
****
The answer:
In sexually reproducing organisms
