6. add a noun to the beginning of the sentence (subject-verb-object, it has the verb as "ran" and the object as "room" but it's missing a subject)
7. add a comma between the two independent clauses ("but" only requires a comma in front of it for it to be grammatically correct within this sentence, not a semicolon and a second conjunction)
8. is the same as number 7 ??
9. place the words that are describing what you want to explain next to what you are explaining. (while that answer choice is rather horribly phrased, "hot" is the misplaced modifier--the bowl itself isn't what's hot, the soup is hot. you'll want to move hot to stand in front of the soup)
10. add a verb to tell what he did in the rocket ship. (subject-verb-object again, you have the subject "he," no verb, and the object "rocket." you'll want to throw a verb in between "he" and "in" to complete the sentence)
