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.

do you know the story wonder?

well on wonder it has different stories from each person and they can all share their thoughts and feeling each not just one. if there was one you would only get to see one persons thoughts and feelings. so do a story point on multiple of the main characters.

hope i !

nobody can deny that cars are the most used means of transport all over the world. however owing a car could have some disadvantages. first of all, having a car on your own allows you to go everywhere without depending on timetables. moreover, you can use it whenever you need it no matter the time or the climate conditions. furthermore, if you have a car, you would not have to wait for nobody to share it when going to somewhere. nevertheless, one major disadvantages of owing a car is the fact that fuel is very expensive nowadays so that not everyone can afford it. in addition, you have to pay insurance to be protected by legal conditions. apart from this, the person who owns a car always has to maintain the car and repair any mechanical problem which could costs a huge amount of money. what is more, if you have to travel long distances, and you do not like driving, one probably would be exhausted and irritated due to driving for a long time. besides, cars cause environmental pollution. to sum up, owing a car means that you have more freedom to travel whenever and wherever people want to, however the car maintenance could be a very expensive issue that can have bad consequences at your economy.
