Immunology is strongly experimental in everyday practice but is also characterized by an ongoing theoretical attitude. Many theories have been suggested in immunology from the end of the nineteenth century up to the present time. The end of the 19th century and the beginning of the 20th century saw a battle between "cellular" and "humoral" theories of immunity. According to the cellular theory of immunity, represented in particular by Elie Metchnikoff, it was cells more precisely, phagocytes that were responsible for immune responses. In contrast, the humoral theory of immunity, held by Robert Koch and Emil von Behring, among others, stated that the active immune agents were soluble components (molecules) found in the organism's "humors" rather than its cells.

Cellular immunology expressed the theory that what cells caused immune responses?
Answer: phagocytes

Problem: Since the early 1990s, Estonia is involved in active trilateral Baltic states co-operation with Latvia and Lithuania, and Nordic-Baltic co-operation with the Nordic countries. The Baltic Council is the joint forum of the interparliamentary Baltic Assembly (BA) and the intergovernmental Baltic Council of Ministers (BCM). Nordic-Baltic Eight (NB-8) is the joint co-operation of the governments of Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, Norway and Sweden. Nordic-Baltic Six (NB-6), comprising Nordic-Baltic countries that are European Union member states, is a framework for meetings on EU related issues. Parliamentary co-operation between the Baltic Assembly and Nordic Council began in 1989. Annual summits take place, and in addition meetings are organised on all possible levels: speakers, presidiums, commissions, and individual members. The Nordic Council of Ministers has an office in Tallinn with a subsidiary in Tartu and information points in Narva, Valga and Parnu. Joint Nordic-Baltic projects include the education programme Nordplus and mobility programmes for business and industry and for public administration.
Which Baltic countries have cooperated with Estonia since the early 1990s?
The answer is the following: Latvia and Lithuania

The purpose of these instruments was to address the various forms of corruption (involving the public sector, the private sector, the financing of political activities, etc.) whether they had a strictly domestic or also a transnational dimension. To monitor the implementation at national level of the requirements and principles provided in those texts, a monitoring mechanism the Group of States Against Corruption (also known as GRECO) (French: Groupe d'Etats contre la corruption) was created.
The instruments used to point out the different corrupt forms looked to see if they were rigidly domestic or what?
transnational

Input: Solar energy
Development of a solar-powered car has been an engineering goal since the 1980s. The World Solar Challenge is a biannual solar-powered car race, where teams from universities and enterprises compete over 3,021 kilometres (1,877 mi) across central Australia from Darwin to Adelaide. In 1987, when it was founded, the winner's average speed was 67 kilometres per hour (42 mph) and by 2007 the winner's average speed had improved to 90.87 kilometres per hour (56.46 mph). The North American Solar Challenge and the planned South African Solar Challenge are comparable competitions that reflect an international interest in the engineering and development of solar powered vehicles.

What is the name of the solar powered car race held every two years?
Output: The World Solar Challenge

Input: Article: In ring-porous woods of good growth it is usually the latewood in which the thick-walled, strength-giving fibers are most abundant. As the breadth of ring diminishes, this latewood is reduced so that very slow growth produces comparatively light, porous wood composed of thin-walled vessels and wood parenchyma. In good oak these large vessels of the earlywood occupy from 6 to 10 percent of the volume of the log, while in inferior material they may make up 25% or more. The latewood of good oak is dark colored and firm, and consists mostly of thick-walled fibers which form one-half or more of the wood. In inferior oak, this latewood is much reduced both in quantity and quality. Such variation is very largely the result of rate of growth.

Now answer this question: Does slow or rapid growth make relatively porous, light wood?

Output: slow

Problem: Hard rock developed into a major form of popular music in the 1970s, with bands such as Led Zeppelin, The Who, Deep Purple, Aerosmith, AC/DC and Van Halen. During the 1980s, some hard rock bands moved away from their hard rock roots and more towards pop rock, while others began to return to a hard rock sound. Established bands made a comeback in the mid-1980s and it reached a commercial peak in the 1980s, with glam metal bands like Bon Jovi and Def Leppard and the rawer sounds of Guns N' Roses, which followed up with great success in the later part of that decade. Hard rock began losing popularity with the commercial success of grunge and later Britpop in the 1990s.
What style did some hard rock bands embrace in the 1980s?
The answer is the following:
pop rock
