Seems like you have chosen the wrong section, next time check it carefully and you will get the answer sooner. Anyway, the main advantage of mathematics which was used to support the claims of the scientific revolution is that this study appeals with facts not ideas or opinions which means it can leave an irrefutable proof, and it did it.
Hope that helps!

One way to vary the syntax of the text is to combine sentences since, in this way, your structures will be longer and more complex to follow. This could be done by means of links such as: however, in addition, therefore, etc. When using these words, you create semantic relations between the syntactic structures and make the reading process more difficult because, as I've I said, sentences become longer and therefore the reader has to keep more information in mind to follow the train of thought.
You could also vary the syntax by adding phrases or clauses. This option is similar to the previous one since it also refers to the complexity of the syntactic structures of the text.
