Explanation:

For Ralph Waldo Emerson: He is known for writing the literary work "Nature".
For John C. Calhoun: He wrote "The Clay Compromise Measures" but was too sick to deliver them to the Senate, and he was a slave - owner from South Carolina (often associated with Tennessee - like Southern states in terms of pro - slavery stance) who was involved in Congress.

Answer:

Ralph Waldo Emerson: Wrote the literary work, Nature.
John C. Calhoun: Wrote, The Clay Compromise Measures – but was too sick to deliver them to the Senate. (and also "A slave - owner from Tennessee who was elected to congress and ultimately President of the United States" is incorrect for him, the correct association is with the compromise measures and his pro - slavery, political role; the other option about being a slave - owner and in congress fits his profile as a South Carolina politician with pro - slavery views, though the Tennessee part is a bit off, but among the options, this and the compromise measures are related to him. However, more accurately, the "Wrote, The Clay Compromise Measures – but was too sick to deliver them to the Senate" is a key action of his.)
