One of the dependencies that, when found in the summary but not in the article, indicates a possible error is the "pobj" (object of preposition) dependency.
Furthermore, we only match *pobj* dependencies when the target word is "in", as in this example.
The sentence here is not a factual error per se, but rather a readability issue. The "in" should be dropped to make the sentence correct.
For better examples with this specific dependency, try choosing another article. TODO: readability issue with the dependency graph for this specific issue
