the correct option is d

in the generalized crisis environment that the united states was experiencing in the 2000s, one of the most serious problems was the crisis of the public education system. the low rates of academic achievement and the failure of standardized tests by tens of thousands of students in poor and marginalized communities are combined with constant budget cuts and privatization currents in the public education sector. to all this is added a fundamental problem. education in the united states responds to an educational model that functions as a commodity; that is, something that can be sold or bought. however, there is no serious reference to the development of the student body as integral human beings that respond to a series of values such as honesty, cooperation and solidarity.

in all honesty, it really hasn't. except that hitler killed himself.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
