Based on the given passage above, I can say that the sentences that have errors are sentences 3 and 6. On sentence 3, the erroneous part is "considering writing". The sentence could be written well like this: She strongly considers writing about <span>Sally Ride, because he was the first American woman in space. On sentence 6, the erroneous part is the use of "is" instead of "are" after the word "options". </span>
