I have Googled profusely with no luck since this is very specific, it seems. When using a semicolon, most sentences continue the same subject.
“He likes potatoes; he eats them all day.”
But what if the first part was focusing, not on him, but on the object? Could you switch, then, to him after the semicolon?
“The potatoes were very good; He ate them all day.”
Or does the second part HAVE to stay with the same subject?
“The potatoes were very good; they were eaten all day.” (or the first example I gave).
The assignment I have includes an example similar to this, but with the person buying shoes.
“”The shoes are too expensive; I am going to buy them anyway.
