Imagine you are in a 2D grid of size 5x5. You start at the bottom left cell (1,1) and your goal is to reach the top right cell (5,5). However, there are obstacles in cells (2,2), (3,3), and (4,4). You can only move right or up. How many unique paths can you take to reach the goal? Your answer should have exactly 5 paragraphs. Make sure that the first paragraph starts with the word "bureaus" and that each paragraph is separated by two new lines.
