Answer:
B. Thomas Paine’s Common Sense was published in 1776, and the Revolutionary War began that same year.
Explanation:
In sentence construction and framing, the use of the appropriate conjunction is the key to making sure the sentence doesn't sound awkward and unstructured. And in the combination of the two sentences, the best conjunctive word is "and".
Since the two sentences are talking about events that happen in the same time/ year, the joining word will have to indicate the duality of the years. So, by the use of "and" to join the two sentences, the new sentence will have the same sense of what they talk about.
Thus, the final correct sentence will be -
"Thomas Paine’s Common Sense was published in 1776, and the Revolutionary War began that same year."
