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.
Humoral immunology theorized that the origin of the immune system lay in what?
****
The answer: soluble components (molecules)

The problem: Answer a question about this article:
According to Der Spiegel, credits given to European governments were disguised as "swaps" and consequently did not get registered as debt because Eurostat at the time ignored statistics involving financial derivatives. A German derivatives dealer had commented to Der Spiegel that "The Maastricht rules can be circumvented quite legally through swaps," and "In previous years, Italy used a similar trick to mask its true debt with the help of a different US bank." These conditions had enabled Greek as well as many other European governments to spend beyond their means, while meeting the deficit targets of the European Union and the monetary union guidelines. In May 2010, the Greek government deficit was again revised and estimated to be 13.6% which was the second highest in the world relative to GDP with Iceland in first place at 15.7% and Great Britain third with 12.6%. Public debt was forecast, according to some estimates, to hit 120% of GDP during 2010.
Why weren't swaps registered as debts by Eurostat at the time?
****
The answer: ignored statistics involving financial derivatives

The problem: Answer a question about this article:
As the premiers did not come to an agreement on this question, the Parliamentary Council was supposed to address this issue. Its provisions are reflected in Article 29. There was a binding provision for a new delimitation of the federal territory: the Federal Territory must be revised ... (paragraph 1). Moreover, in territories or parts of territories whose affiliation with a Land had changed after 8 May 1945 without a referendum, people were allowed to petition for a revision of the current status within a year after the promulgation of the Basic Law (paragraph 2). If at least one tenth of those entitled to vote in Bundestag elections were in favour of a revision, the federal government had to include the proposal into its legislation. Then a referendum was required in each territory or part of a territory whose affiliation was to be changed (paragraph 3). The proposal should not take effect if within any of the affected territories a majority rejected the change. In this case, the bill had to be introduced again and after passing had to be confirmed by referendum in the Federal Republic as a whole (paragraph 4). The reorganization should be completed within three years after the Basic Law had come into force (paragraph 6).
In the revision of Article 29, what was a binding provision for a new delimitation of the federal territory?
****
The answer:
the Federal Territory must be revised
