Arsenal's financial results for the 2014–15 season show group revenue of £344.5m, with a profit before tax of £24.7m. The footballing core of the business showed a revenue of £329.3m. The Deloitte Football Money League is a publication that homogenizes and compares clubs' annual revenue. They put Arsenal's footballing revenue at £331.3m (€435.5m), ranking Arsenal seventh among world football clubs. Arsenal and Deloitte both list the match day revenue generated by the Emirates Stadium as £100.4m, more than any other football stadium in the world.
How much of Arsenal's profits come from their footballing core?
A: unanswerable

In most bacteria, a cell wall is present on the outside of the cell membrane. The cell membrane and cell wall comprise the cell envelope. A common bacterial cell wall material is peptidoglycan (called "murein" in older sources), which is made from polysaccharide chains cross-linked by peptides containing D-amino acids. Bacterial cell walls are different from the cell walls of plants and fungi, which are made of cellulose and chitin, respectively. The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan. The cell wall is essential to the survival of many bacteria, and the antibiotic penicillin is able to kill bacteria by inhibiting a step in the synthesis of peptidoglycan.
How can antibiotic penicillin destroy bacteria?
A: by inhibiting a step in the synthesis of peptidoglycan

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
