So we've come here today to dramatize a shameful condition. In a sense, we've come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. ( This note was the promise that all men, yes, black men as well as white men, would be guaranteed the unalienable rights of life, liberty, and the pursuit of happiness. )
Which word provides the best context clue to determine the meaning of "unalienable" in this paragraph?
A- Shameful
B -Architects
C -Promise
D-Guaranteed
