Frankenstein speaks of the "enticements of Science." After the Scientific Revolution, what fears did people have about these scientific enticements? Chapter 3, pg. 30: "None but those who have experienced them can conceive of the enticements of Science.

A complex sentencen is made up of two  clauses: a main clause and a subordinating clause.

-Designing shoes is hard work; however, it will pay off in the end.( These are two independent clauses linked by however),

- Designing shoes is hard work; it will pay off in the end (These are two independent clauses linked by semi colon).
