What is the purpose of this excerpt from the article "what is gis? "?

gis also can be used for complex modeling to answer a wide range of "what if" and ecosystem simulation questions. these may be cartographic models designed to document the co-occurrence or interrelationship of multiple data layers or they may be hypothetical research models designed to mimic natural ecological systems. similarly, modeling with gis can be used to predict the impacts that one set of parameters will have on another. for example, wetlands, soils, hydrography, climatology and elevation data can be combined to model flooding within a river system. upstream changes in land use within the same system can be modeled to determine the potential impact of conversion of a forested floodplain to residential development or to agriculture. as a result, both natural system responses to storm events and the impact of human land use decisions can be assessed prior to the proposed action.

a) to warn readers about the hazards of diminishing wetlands
b) to inform readers about the multiple uses of gis
c) to explain the workings of the ecosystem simulations
d) to instruct readers about proper use of gis resources

B) to inform readers about the multiple uses of GIS.

Explanation: when writing, an author can have several different purposes, for example: to inform, to entertain, to persuade, to criticize, etc. In the given excerpt from the article "What Is GIS?" we can see that the writer describes some of the multiple uses of GIS (like making cartographic models, or hypothetical research models that mimic natural ecological systems, etc). So the correct answer is option B: the purpose of the excerpt is to inform readers about the multiple uses of GIS.

1. this would be first person. it would be like "i walked home from school today" they are the narrator of the story and is a character as well.

2. first person because they used the word "i" in the quote.

3. i'm really not sure about this one i'm really sorry i never read it so i wouldn't know how to answer it. 

4. it would be character vs. society because everyone he meets there is always a conflict of some sort because he's stuck in his daydream.

5. it would be sadness at the loss of youth because the title itself tells us it's about age so it couldn't be about regret. and the tone just sounds sad, not angry. 

i hope this !

both inform the reader that faryad and liaqat were not given the chance to tell their version of events at the police station.

hope this
