Answer:
"'I am much grieved, for I expected, if I did not defeat you, to hold out much longer, and give you more trouble before I surrendered.'"
Step-by-step explanation:
The given quotes are taken from the "1832 Surrender Speech" of the Indian leader Black Hawk. The speech details his regret in being unable to defend his people against the white men and also his surrender to their hands.
Among the given quotes from the speech, the lines "'I am much grieved, for I expected, if I did not defeat you, to hold out much longer, and give you more trouble before I surrendered.'" best express the major theme of the whole speech. This was because the main point made in the speech was to acknowledge his surrender and also his regret for the unsuccessful attempts to defend his people and their land.
Thus, the correct answer is the second option.
