The road ahead will be long. our climb will be steep. we may not get there in one year or even one term, but america i have never been more hopeful than i am tonight that we will get there. i promise you we as a people will get there. there will be setbacks and false starts. we know government can't solve every problem. but i will always be honest with you about the challenges we face. i will listen to you, especially when we disagree. and above all, i will ask you to join in the work of remaking this nation the only way it's been done in america for two-hundred and twenty one years block by block, brick by brick, calloused hand by calloused hand. the phrase “calloused hand by calloused hand ” implies all of the following except a. the u. s. was built through the use of slave labor. b. building the u. s. was a long, tough process. c. growth of the country involved hard, physical labor. d. building a nation is not an easy job.

in   ¨and yet the books¨   by czelaw miloz the tone is positive since it tells us that when we touch a book, it starts to live and the perspective is in the third person and turns once into the first person. in "the rhinoceros" by eugene ionesco the tone is illogical and absurd   and the perspective is in the third person since it is a play.

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.
