Answer:
Option A: Andrew is content to stay on the family farm, while Robert dreams of traveling.
and
Option C: Andrew enjoys working the land when Robert prefers reading and thoughts of adventure.
Step-by-step explanation:
Option A is correct because Andrew's is a farmer by nature. He is Robert's hardy elder brother, While Robert is of delicate, poetic and romantic nature. He loves to read books and travelling.
Option C is also correct because it says the same thing in option A but in different words. Andrew is a hard worker. He knows exactly how to manage a farm, while Robert being of poetic nature and fond of reading books is not able to properly manage the farm, which in the end is in full disarray.
Option B is not correct: They both care much about their family. One of the reason behind Robert's plan to leave the farm and go on sea voyage was that he loved Ruth and wanted not to interfere in Ruth future with Andrew proposed marriage. When it becomes known that Ruth loves Robert and not Andrew, Andrew leaves because he too did not want to interfere in Robert's future with Ruth.
Option D is not correct: Firstly this option does not show any contrast between the two brothers. Secondly, Although Andrew told Robert that he would miss him, but it does not mean that he was resentful.
