You may have researched articles on gerontology and found studies that answered three basic questions on how older adults respond to training for physical performance.
You might divide the paper as follows:
Question 1
Question 2
Question 3

In order for you to see this concept with a real-life example, you can access a sample synthesis or literature review from a psychology student by clicking here. The student writes her paper on the following topic: Emotional Eating: The Perpetual Cycle of Mood-Food Influence. She divides her literature into the following categories:
Influence of Mood on Eating Behavior
Gender Differences
Influence of Eating Behavior on Later Moods
Chronic Stress Response Network
Notice how she synthesizes and integrates the research into the different categories.

Approach and Requirements
Your synthesis essay, or literature review, should be 2000-2500 words, not including your “references” pages at the end of the review.  In other words, the text of the paper should be 2000-2500 words.
In addition your synthesis essay should include at least 10 scholarly sources in the “references” section.  As stated above, this means that you may decide not to use all 12 sources that you summarized in your annotated bibliography.  You are free to use all 12 of them.  However, it is possible that your experience in writing summaries of the 12 sources led you to conclude that a few of them will not be as helpful to your topic as you had originally thought.  You may decide not to include such sources in the synthesis essay.  This is totally up to you.  Moreover, you might find other sources that you would like to include in your synthesis essay that were not included in your annotated bibliography.  You may use such sources in your synthesis essay as well.
