Which statement about Greek plays is true? A. In comedies, men played female characters and women played male characters. B. Men played all the characters, both male and female. C. There were no women actors because there were no female roles in Greek plays. D. Only unmarried women could perform in Greek plays.

B. Men played all the characters, both male and female

Explanation

Men played the role of both male and female in Greek theatres.

A male actor could play the role of three different people in one play. This was because of the role of the women in Greek culture which saw women as being inherently inferior to men and because of the importance of drama to the Greek, women were not allowed to participate in plays in any form so the males played all the roles that were available in a play.

Women in Greece then were seen to be lower than slaves, that's how low they were viewed in Greek society.

The Greeks considered allowing a female on set was too dangerous so they allowed men act all characters of a play.

development:   floodplain development often directly impacts wetlands by removing vegetation (increasing bank erosion),   and filling or draining wetlands for building sites.   floodplain development sometimes indirectly impacts riparian wetlands through the installation of artificial stream stabilizing devices like rip-rap and bulk-heads that attempt to stop the natural meandering process which creates new wetlands and replenishes existing ones.    

road building:   most river valleys have roads and/or railroads.   these structures squeeze rivers and streams by narrowing the floodplain.   this destabilizes the river which   has less room to meander and therefore has an excess of energy.   the roads and railroads also affect drainage from uplands onto the floodplains, and many are built on top of areas that once were wetlands.   such roads often create long, low-quality wetlands upslope of the road by interrupting surface and groundwater flows.   these wetlands can attract wildlife dangerously close to roads.   wetland loss caused by roads is mitigated through the restoration of other impacted wetlands although the replacement wetlands are not always of the same type and quality as those lost. see montana department of transportation's off-site wetland mitigation reserves map.

grazing: overgrazing harms wetlands through soil compaction, removal of vegetation, and stream bank destabilization.   wetlands offer some of the best forage for livestock as well as a water source and cover, so livestock tends to spend a disproportionately large time in wetlands.   there are many grazing strategies that discourage cattle from using wetlands. click on rwrp's web site for a discussion of these strategies.

agriculture:   wetlands often have fairly flat areas of rich organic soil that is highly productive agricultural land if drained.   for this reason many wetlands have been drained and converted to agricultural lands.  

mining: historic mining has had a major impact on wetlands of the clark fork basin, particularly along the upper river where mine wastes have been deposited in the floodplain, creating the country’s largest superfund site. view the superfund site.  

the epa also list the following as major human causes of wetland loss:   logging,   runoff, air and water pollution, introducing nonnative species. see examples of nonnative species here.

the following lists specific damaging actions commonly taken in wetlands.

dumping:   dumping fill material buries hydric soils and effectively lowers the water table so hydrophytic (water loving) plants cannot compete with upland plants.  

            dredging:   the removal of material from a wetland or river bed.   dredging of streams lowers the surrounding water table and dries up adjacent wetlands.

            draining:   water is drained from wetlands by cutting ditches into the ground which collect and transport water out of the wetland.   this lowers the water table and dries out the wetland.    

            diverting flow:   water is diverted around wetlands, lowering the water table.  

            devegetation:   vegetation plays an important role in wetland ecology by removing water through evapotranspiration, altering water and soil chemistry, providing habitat for wildlife, and reducing erosion.   removal of vegetation can drastically and sometimes irreversibly alter wetland function.

            damming flow:   many ponds and reservoirs are constructed on wetlands.   a flooded wetland cannot provide the same habitats and functions.  

            development of springs:   pumping large quantities of water from springs lowers nearby groundwater and can result in the loss of wetland vegetation.   compaction of springs by cattle can cause springs to cease to flow.

explanation:

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
