Answer:
Robert: “What I want to do now is keep on moving so that I won’t take root in any one place”
Step-by-step explanation:
This sentence said by Robert to his brother Andrew in the beginning of Eugene O’Neill’s play Beyond the Horizon” reflects Robert’s dream of leaving the farm. Before this sentence Andrew says to Robert that he should have gone back to college for completing his studies. But Robert tells him that he left college because their father wanted to save money, and further even if their father had not wanted so, he would have left college because what he (Robert) really wanted to do was keep moving, because he did not like the idea to stay at any one place.
There are some other references too about Robert’s dream of leaving the farm, for example poetry from the poetry book Robert was reading, (read by Andrew) has these lines,
"I have loved wind and light and the bright sea. But holy and most sacred night, not as I love and have loved thee."
But the sentence spoken by Robert himself reflects his dream most clearly.
