Two individuals are trying to enhance their overall problem-solving abilities. Person A decides to solve the same type of logic puzzle every day for a month, aiming to become faster and more accurate. Person B decides to spend the same amount of time each day but tackles a different kind of mental challenge each week—such as spatial reasoning tasks, word puzzles, and strategic games. Evaluate which individual's approach is likely to be more effective for developing broad, transferable problem-solving skills that can be applied to a wide range of real-world challenges. Justify your reasoning.
