Question: Infection begins when an organism successfully enters the body, grows and multiplies. This is referred to as colonization. Most humans are not easily infected. Those who are weak, sick, malnourished, have cancer or are diabetic have increased susceptibility to chronic or persistent infections. Individuals who have a suppressed immune system are particularly susceptible to opportunistic infections. Entrance to the host at host-pathogen interface, generally occurs through the mucosa in orifices like the oral cavity, nose, eyes, genitalia, anus, or the microbe can enter through open wounds. While a few organisms can grow at the initial site of entry, many migrate and cause systemic infection in different organs. Some pathogens grow within the host cells (intracellular) whereas others grow freely in bodily fluids.
Is there an answer to this question: What individuals are particularly safe to opportunistic infections?

Answer: unanswerable

Question: An important idea in the definition of a university is the notion of academic freedom. The first documentary evidence of this comes from early in the life of the first university. The University of Bologna adopted an academic charter, the Constitutio Habita, in 1158 or 1155, which guaranteed the right of a traveling scholar to unhindered passage in the interests of education. Today this is claimed as the origin of "academic freedom". This is now widely recognised internationally - on 18 September 1988, 430 university rectors signed the Magna Charta Universitatum, marking the 900th anniversary of Bologna's foundation. The number of universities signing the Magna Charta Universitatum continues to grow, drawing from all parts of the world.
Is there an answer to this question: What did the Constitution Habita guarantee to all travelers?

Answer: unanswerable

Question: In the 20th century, the Paris literary community was dominated by Colette, Andre Gide, Francois Mauriac, Andre Malraux, Albert Camus, and, after World War II, by Simone de Beauvoir and Jean-Paul Sartre; Between the wars it was the home of many important expatriate writers, including Ernest Hemingway, Samuel Beckett, and, in the 1970s, Milan Kundera.

Is there an answer to this question: During what war did Modiano base most of his work off of?

Answer: World War II

Question: The current US fleet of Nimitz-class carriers will be followed into service (and in some cases replaced) by the ten-ship Gerald R. Ford class. It is expected that the ships will be more automated in an effort to reduce the amount of funding required to staff, maintain and operate its supercarriers. The main new features are implementation of Electromagnetic Aircraft Launch System (EMALS) (which replace the old steam catapults) and unmanned aerial vehicles. With the deactivation of USS Enterprise in December 2012 (decommissioning scheduled for 2016), the U.S. fleet comprises 10 active supercarriers. On 24 July 2007, the House Armed Services Seapower subcommittee recommended seven or eight new carriers (one every four years). However, the debate has deepened over budgeting for the $1214.5 billion (plus $12 billion for development and research) for the 100,000 ton Gerald R. Ford-class carrier (estimated service 2016) compared to the smaller $2 billion 45,000 ton America-class amphibious assault ships able to deploy squadrons of F-35B of which one is already active, another is under construction and nine more are planned.
Is there an answer to this question: When is the USS Enterprise scheduled to be commissioned?
