That's to inform because its just telling you information
Answer:
A- Robert <u>polished</u> his saddle.
Explanation:
If you take out "his saddle", the sentence does not make sense. Taking out "for the wagon", the sentence will still make sense. If you can take out the word(s) that the verb is applying to (what is Robert doing, he's polishing his saddle), and if the sentence does not make sense, then it is a transitive verb.
Options two refers to the author being a teenager himself so he would be reliable for this info because it is firsthand.
