-费力的蚂蚁在5x5的网格上随机行走。 步行从中央广场开始。 在每个步骤中，蚂蚁都会随机移动到相邻的正方形，而不会离开网格。 因此，根据蚂蚁的位置，每一步有2、3或4种可能的移动。
+A laborious ant walks randomly on a 5x5 grid. The walk starts from the central square. At each step, the ant moves to an adjacent square at random, without leaving the grid; thus there are 2, 3 or 4 possible moves at each step depending on the ant's position.
 
-步行开始时，将种子放在下排的每个正方形上。 当蚂蚁不携带种子并到达包含种子的下排的正方形时，它将开始携带种子。 蚂蚁会将种子放在最终到达的上一行的第一个空方格上。
+At the start of the walk, a seed is placed on each square of the lower row. When the ant isn't carrying a seed and reaches a square of the lower row containing a seed, it will start to carry the seed. The ant will drop the seed on the first empty square of the upper row it eventually reaches.
 
-在将所有种子都放到第一行之前，预期的步骤数是多少？ 将答案四舍五入到小数点后六位。
+What's the expected number of steps until all seeds have been dropped in the top row? Give your answer rounded to 6 decimal places.
