Final answer:
The sentence from the passage that makes a specific claim is 'He secured the people in the title to their lands, and removed the last chain of oppression,' as it asserts a definite action taken in the past.
Step-by-step explanation:
The sentence from the passage that makes a specific claim is:
A. He secured the people in the title to their lands, and removed the last chain of oppression.
This sentence asserts a definite action was taken, namely securing land titles for people and the removal of oppression, which can be supported or contested with evidence, making it a specific claim. Option B is a call for future aspirations, option C is an expression of sentiment, and option D is a stated intention, none of which are concrete claims about past actions like option A.
