We were flipping through the research books zealously looking for any apparent solution to the question that our teacher tossed to us. The normally phlegmatic Ryan sprung into action. He was finding any clues on the question meticulously. As time elapsed, there has not been any useful lead in our search for the mysterious answer. Finally after many fruitless attempts to find out the solution, we found something that was almost identical to the question posted by our teacher. We copied down the answer and use it as cross reference with the other reference books, after a long wait, we finally got the answer that we deemed correct. As we left the library, a grin was on our faces. We finally broke the mystery!
