Answer:
The best way to revise sentences 1 and 2 to create sentence variety is: History interests me. The Declaration of Independence is something I decided to read.
Step-by-step explanation:
Fronting of objects is a good way to show sentence variety - by moving the object to the subject position in both sentences we create a more enganging text for the reader. Sentences 1 and 2 may seem monotonous and simple, with no style at all. By changing the pattern and the length of the sentences we are making the text more emphatic.
