Answer:
These two options (first and third) provide the main contrast between Andrew and Robert. Other options are just outcome of the situation.
1) Andrew is content to stay on the family farm, while Robert dreams of traveling.
3) Andrew enjoys working the land when Robert prefers reading and thoughts of adventure.
Step-by-step explanation:
Andrew and Robert Mayo are two brothers from Eugene O'Neil's play "Beyond the Horizon". They both love Ruth Atkinson. There are many contrasts between the two brothers. Andrew is the elder brother. He is a farmer who likes to stay on the farm, is more practical of the two brothers, more caring towards his family, and is always willing to sacrifice.
Robert, the younger of the two, is of romantic, poetic and adventure loving nature. He daydreams about traveling to far off ends of the world. However because he loves Ruth Atkins, he decides against leaving the farm and stays on home. Andrew takes his place on the sea voyage.
Second option is not correct because both of them care about their family's wishes, yet none is able to make their care count. Andrew leaves the farms against family's wishes (although in favor of his brother). Three years later when Andrew returns, his family wishes him to stay and manage the farms, but he leaves again.
Fourth option is not correct, because earlier Andrew was resentful about Robert leaving the farm, but when Andrew leaves, it was Robert who was resentful.
