1. The problem asks whether the statement "Not all college students in Country B are willing to marry without romantic love" is true or false based on the bar graph data. 2. From the graph, the percentage of college students in Country B willing to marry without romantic love is about 40%. 3. The statement "Not all college students in Country B are willing to marry without romantic love" means that there exists at least one student in Country B who is not willing to marry without romantic love. 4. Since only 40% are willing, it implies 60% are not willing, so the statement is true. 5. The negation of the statement "Not all are willing" is "All college students in Country B are willing to marry without romantic love," which is false given the data. 6. Therefore, the correct choice is B: The statement is true because its negation is false. If a negated statement is false, then the initial statement is true.
