Based on the given paragraph, the statement that would shift the nation X's PPC is the statement: "Within three months of coming into office, Bertolini passed regulations that made college education available to students from low-income families". This is so because the statement shows a great achievement coming from a female president from an island who accomplished so much within a short period of time. The other statements are just supporting statements of the main spotlight statement. For example, the last statement about the female astronaut is out of context, therefore, we cannot refer this as the main content of the paragraph. <span />
