Before you even start your essay, it is important to explain what the word "synthesis" means.
It is a mix of elements used to draw the whole picture.
Make sure all gathered sources are related to your essay topic.
Also, they have to be no older than 5-10 years as things change dynamically.
In case your essay is going to have three main sections, divide the outline into three chunks respectively.
Insert evidence to support your thesis, include sub-arguments along with all specific points.
Make sure to decide on the text that may have opposing views.
In other words, choose an article with the strong argument which may encourage your readers not just to read the synthesis essay from cover to cover, but also go on discussing the selected questions.
