Explanation:
Gerald Graff started his article on Hidden Intellectualism with the example of Warner who had a Pentecostal background but was now a strong atheist. There is a sharp contrast between these two backgrounds because both have very opposing views. But Warner recognized the fact that indeed, his Pentecostal background which was saturated with arguments about beliefs helped him develop his intellectual prowess and ability to question matters.
Sports gave the same advantage to Gerald Graff for he noted that as a child who loved sports more than books, he argued a lot with his mates about certain things they considered unfair in the course of play. These series of arguments during sports was gradually shaping him to develop his ability to question things. From there too, he developed the five abilities listed above.
