Which line in this excerpt from Robert Frost’s “Mending Wall” suggests that the speaker and his neighbor are quite different? There where it is we do not need the wall:
( He is all pine and I am apple orchard. )
My apple trees will never get across
And eat the cones under his pines, I tell him.
( He only says, "Good fences make good neighbours." )
Spring is the mischief in me, and I wonder If I could put a notion in his head:
( "Why do they make good neighbours? ) Isn't it
Where there are cows? But here there are no cows.
Before I built a wall I'd ask to know
( What I was walling in or walling out, )
And to whom I was like to give offence.
( Something there is that doesn't love a wall, )
That wants it down."

The “big dig” the “big dig” (the central artery/tunnel project) has been complex and challenging. located in boston, massachusetts, this tunnel is eight lanes wide and three-and-a-half miles long. what is most amazing about this tunnel is that it is constructed under a major highway and skyscrapers located in boston’s financial district. construction crews used “clamshell excavators” during this dig. these machines carved narrow trenches, and then a special substance was pumped into the trench to keep the dirt from caving in. finally, steel beams were lowered into the trench and concrete was pumped in. one problem that engineers faced while constructing the tunnel is the fact that the soil beneath boston is extremely loose and soggy. engineers solved this dilemma by freezing the soil and pumping very cold water into pipes beneath the city. to strengthen the soil even further, a special type of glue was injected into the ground to with the consolidation of the soil. 23 which phrase best defines the word excavator as used in the passage? a. a device used to measure underground temperatures b. a device used to level uneven surfaces c. a device used to move heavy objects d. a device used to dig holes
