Answer:
The sentences aren't following grammatical rules. You need to rephrase it, like this:
Instead of, "A controversial character, people were shocked by Lord Byron".
You could write, "People were shocked by Lord Byron, who was a controversial character"
Doesn't it just sound more.. english-y? Let's do another.
Instead of, "A gloomy mysterious outcast, The Byronic hero feels no satisfaction in their accomplishments".
You could write, "The Byronic hero, a gloomy mysterious outcast, feels no satisfaction in their accomplishments". The "their" might also need to be changed to a "he" if this is talking about a single character.
The third one is structured correctly, but it uses the wrong tense (past, future, present) Drove vs Drive .... Felt vs Feel. Your incorrect word is "were"
The fourth uses the wrong "there" vs "their"
The fifth refers to Mary Shelly as a he. "His" needs to be changed.
