Problem: Bacteria:

In ordinary circumstances, transduction, conjugation, and transformation involve transfer of DNA between individual bacteria of the same species, but occasionally transfer may occur between individuals of different bacterial species and this may have significant consequences, such as the transfer of antibiotic resistance. In such cases, gene acquisition from other bacteria or the environment is called horizontal gene transfer and may be common under natural conditions. Gene transfer is particularly important in antibiotic resistance as it allows the rapid transfer of resistance genes between different pathogens.

What is horizontal gene transfer?
---
A: gene acquisition from other bacteria or the environment


Problem: The Bronx:

Starting in the 1970s, the Bronx often symbolized violence, decay, and urban ruin. The wave of arson in the South Bronx in the 1960s and 1970s inspired the observation that "The Bronx is burning": in 1974 it was the title of both a New York Times editorial and a BBC documentary film. The line entered the pop-consciousness with Game Two of the 1977 World Series, when a fire broke out near Yankee Stadium as the team was playing the Los Angeles Dodgers. Numerous fires had previously broken out in the Bronx prior to this fire. As the fire was captured on live television, announcer Howard Cosell is wrongly remembered to have said something like, "There it is, ladies and gentlemen: the Bronx is burning". Historians of New York City frequently point to Cosell's remark as an acknowledgement of both the city and the borough's decline. A new feature-length documentary film by Edwin Pagan called Bronx Burning is in production in 2006, chronicling what led up to the numerous arson-for-insurance fraud fires of the 1970s in the borough.
