Answer:
1.Problem and Solution
2.Cause and Effect
3.Compare and Contrast
Explanation:
Problem and Solution: These writings are exactly what one might expect: identifying an issue, giving details about it and suggesting solutions or one solution that is best from many. For example, someone may choose to write about a problem such as population explosion. After explaining the problem in detail, he or she would explore the solutions. Needless to say, the writer also has to justify the solutions proposed and how they can be implemented, if they are actually feasible or not.
Cause and Effect: Why did something happen and what impact it might have are the two central aspects of this type of writing. They may include environmental problem or ask for opinions about an issue and how it will affect the future or what impact does a historic event have on the lives of a nation’s citizen etc. The outcomes can be definitively true or can be based on assumptions, but either way, must be validated.
Compare and Contrast: This type of writings has two features: comparison which works with the similarities of two contents and contrast which works with the differences of the two contents. For example, if you are told to write an essay asking if children should be playing inside or outside the home, you can compare why play is important and then create a contrast to show how one is better or worse than the other.
