12. Explain how historians, archaeologists, anthropologists, and geologists collaborate (work together) to recreate events in history.
What does each do and how do they collaborate?

Archaeologists use written sources to help them find sites where they will find arti- facts. Similarly, historians examine material culture to help them understand what they read.  Anthropologists study the characteristics of past and present human communities through a variety of techniques. In doing so, they investigate and describe how different peoples of our world lived throughout history. To establish a relative time frame, geologists have arranged the rocks in a continuous sequence of chronostratigraphic units on a planetary scale, divided into eonothems, erathemes, systems, series and floors, based on stratigraphy, that is, on the study and interpretation of the strata, supported by major biological and geological events.

the correct answer is: (1) affected by gerrymandering; (2) not affected by gerrymandering.

gerrymandering is known as a practice that intends to establish a some kind of political advantage for a particular party or group. to do this district boundaries are manipulated. the new resulting district is named a gerrymandering.

in other words, what gerrymandering does is to draw the boundaries of electoral districts trying to benefit the party who is doing it. sometimes, the party controlling the legislature will redraw it so they can maximize the number of districts they are likely to control.
