Introduction:

The information presented in your introduction paragraph needs to be presented as if the reader has no prior knowledge of your topic.  Make sure everything you are writing about is clearly stated for any person to understand.  Once you have written the most basic background information about your topic, begin explaining why that information is important for the reader to understand. 

For example, if you decide that the topic of your essay is Fate, you will first need to explain Fate to the reader as if they have no idea what Fate is.  Once you have done that, then you need to spend a few sentences connecting what Fate is to why the reader should care and how the concept of Fate is connected to what you are going to prove.

 

Thesis statement template:

In William Shakespeare's Macbeth, the role/purpose of the Weird Sisters/Witches is (1) to present the destiny/Fate to Macbeth (2)to set the play's actions in motion because ___(1)___, ___(2)___, and ___(3)___.

 

Your listed information needs to be the three main reasons you believe your choice in the beginning of the prompt (the answer to the question).  The three points you have chosen will be the topics for your three body paragraphs.

 

For example:

A few of the options you may use for supporting ideas would be:

-Macbeth was not superstitious before meeting the Witches and hearing the prophecies.

-Fate is not something that can be changed or altered.

-The purpose of the Witches is to deliver Fate, which stems from the definition of the name they are given: Weird Sisters.

-Lady Macbeth gets the idea to help Macbeth become King from the idea that he could become King, but had never had the idea before the prophecy.

-The possibility of Macbeth naturally becoming King without interference is none because of the natural succession of power.

-Lady Macbeth's power-hungry nature is what creates the idea to kill for the crown.

 

There are plenty of other reasons and events that could support your idea.  Make sure whichever 3 you choose there is evidence and you can find quotations from Act I to support your ideas.
