So the question that we had is: How can bacteria, these primitive organisms, tell the difference from times when they're alone and times when they're in a community, and then all do something together?
Soalannya, bagaimana bakteria, organisma primitif ini, mengetahui perbezaaan masa ia bersendirian dan masa ia berada  dalam komuniti, dan kemudiannya  melakukan sesuatu bersama.
