Problem: Beer:

Most beers are cleared of yeast by filtering when packaged in bottles and cans. However, bottle conditioned beers retain some yeasteither by being unfiltered, or by being filtered and then reseeded with fresh yeast. It is usually recommended that the beer be poured slowly, leaving any yeast sediment at the bottom of the bottle. However, some drinkers prefer to pour in the yeast; this practice is customary with wheat beers. Typically, when serving a hefeweizen wheat beer, 90% of the contents are poured, and the remainder is swirled to suspend the sediment before pouring it into the glass. Alternatively, the bottle may be inverted prior to opening. Glass bottles are always used for bottle conditioned beers.

What ingredient is filtered out of most beers when it is packaged in bottles and cans?

A: yeast

Problem: After the constitutional changes of 1974, Tito began reducing his role in the day-to-day running of the state.

Another effective way to decrease the transmission rate of infectious diseases is to recognize the effects of small-world networks. In epidemics, there are often extensive interactions within hubs or groups of infected individuals and other interactions within discrete hubs of susceptible individuals. Despite the low interaction between discrete hubs, the disease can jump to and spread in a susceptible hub via a single or few interactions with an infected hub. Thus, infection rates in small-world networks can be reduced somewhat if interactions between individuals within infected hubs are eliminated (Figure 1). However, infection rates can be drastically reduced if the main focus is on the prevention of transmission jumps between hubs. The use of needle exchange programs in areas with a high density of drug users with HIV is an example of the successful implementation of this treatment method. Another example is the use of ring culling or vaccination of potentially susceptible livestock in adjacent farms to prevent the spread of the foot-and-mouth virus in 2001.
What type of interactions happen within groups of infected individuals in epidemics?
A: extensive interactions

Context and question: During much of its history, and especially during the Francoist dictatorship (19391975), the Catalan language has often been degraded as a mere dialect of Spanish. This view, based on political and ideological considerations, has no linguistic validity. Spanish and Catalan have important differences in their sound systems, lexicon, and grammatical features, placing the language in a number of respects closer to Occitan (and French).
During what dictatorship was Catalan considered a dialect?
Answer: Francoist

Question: According to R. J. Rummel, genocide has 3 different meanings. The ordinary meaning is murder by government of people due to their national, ethnic, racial, or religious group membership. The legal meaning of genocide refers to the international treaty, the Convention on the Prevention and Punishment of the Crime of Genocide. This also includes non-killings that in the end eliminate the group, such as preventing births or forcibly transferring children out of the group to another group. A generalized meaning of genocide is similar to the ordinary meaning but also includes government killings of political opponents or otherwise intentional murder. It is to avoid confusion regarding what meaning is intended that Rummel created the term democide for the third meaning.
Is there an answer to this question: The legal meaning of genocide is contained in which international treaty?

Answer:
Convention on the Prevention and Punishment of the Crime of Genocide
