I don't know what work homework means.
But, I learn something from these things and maybe someone else will, too.
So, here is a step towards the first part.
If it is wrong, you can fix it.


str = "If Robert likes green beans, girls with mustaches, and teddy
bears, John thinks    Robert is strange."

f,g = str.split(/\s+/), "Robert"
p (0...f.size).select{|x| f[x]==g}.map{|y| (y-[3,y].min..y+3)}.map{|z| f[z]}

#> [["If", "Robert", "likes", "green", "beans,"], ["bears,", "John",
"thinks", "Robert", "is", "strange."]]
