text: Anybody couldn't say that they haven't had problems understanding something at any given point in time. Simpily because, everyone can't understand everything right away with no problem/obstacle getting in the way weither it being how the words are phrased or if the vocabulary is too hard to comprehend. FACS could solve this issue right away. As presented in the passage "Dr. Huang predicts, then it could modify the lesson, like an effective human instructor," therefore making it easier for the student or user to understand what is being asked or written. Solving probems much quicker than the instrustor could explaining the information piece by piece.
