Answer: The sentence that demonstrates the correct use of elongated hyphens is "Gideon and Francis took a difficult - but not interesting - science course".
Explanation: Elongated hyphens are added in a sentence to emphasize a particular idea. Therefore, they have the opposite effect of parenthesis, which minimize the information provided. Moreover, elongated hyphens give place to abrupt interruptions. The sentence <u>"Gideon and Francis took a difficult - but not interesting - science course" is the one that uses the elongated hyphens in a correct way because what the writer wants to emphasize is the fact that the science course was not interesting.</u>
