Suppose Thomas Jefferson (April 13, 1743 – July 4, 1826) was an American statesman, diplomat, lawyer, architect, philosopher, and Founding Father who served as the third president of the United States from 1801 to 1809. He had previously served as the second vice president of the United States under John Adams.
Can we infer that "Thomas Jefferson served as the first president of the United States."? Yes, no, or maybe?
