PORT-AU-PRINCE, Haiti — Paul Collier, a leading poverty guru, spent a recent morning here waxing positive about how the world's economic freefall might prove the perfect moment for Haiti to sell more exports like T-shirts and mangoes to Americans.  His improbable enthusiasm coincided with appearances by a bevy of luminaries descending on Haiti this month, including Ban Ki-moon, the United Nations secretary general, and the entire Security Council. All of them came to stress that this destitute nation stands at a crossroads between salvation and "the darkness," as Mr. Ban put it.
Paul will always always understand poverty
Just because Paul might understand things now doesn't mean he'll continue to know things in the future making this statement neither correct nor incorrect. The model caught Paul will always understand poverty, but it didn't catch Paul will always always understand poverty. The repeating of the word always must have thrown it off. This suggests that the model has problems with longer statements
