Domestication and pastoralism were key aspects in the development of the a) paleolithic era. b) hunter-gatherer age. c) agricultural revolution. d) classical civilizations of greece and rome.

The school board wants you to answer C) Agricultural Revolution, but that is incorrect.

The correct answer would be during the Neolithic Era, so none of the choices would be the right answer.

Explanation: During the Paleolithic Era, which corresponds to the old stone age, people were hunter-gatherers.  This means that they obtained food by hunting animals and by gathering fruits, vegetables, and nuts from local plants.  So options A and B are pretty much the same thing and incorrect.

Domestication and pastoralism developed during the Neolithic or new stone age when people discovered that, if they took care of certain plants, they would grow again and give them more food.  Domestication is not the same thing as agriculture (even though the school system continues to teach it this way).

The Agricultural Revolution actually refers to a much later period in history, during the 18th century in Britain, when traditional agriculture went through a process of transformation.  This is way after domestication and pastoralism.  

Finally, option D is also incorrect because classical civilizations like Greece and Rome already had full-scale agriculture and had already gone through the process of domestication and pastoralism.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
