Question

Select the correct answer. 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

Answer 1

b:to inform the reader about the multiple uses of GIS

Step-by-step explanation:

Answer 2

B.

Step-by-step explanation:

In the given excerpt, the writer tried to explain the multiple uses of GIS.

GIS (Geographic Information System) can be defined as a framework that helps to better understand the science of the earth. It is a computer system that captures the data of the earth's geographical location.

In the given excerpt, the writer has described the various uses of the GIS. It can be inferred when the writer said repeatedly "can be used."

So, the correct answer is option B.
