When you proof a paper from the bottom to the top you are?

When you proof a paper from the bottom to the top, you are typically focusing on checking for errors in the text in a reverse order, which can help to catch typographical mistakes and grammatical errors that might be overlooked when reading in the conventional top-to-bottom manner. This approach can also encourage greater attention to detail, as it disrupts the natural flow of reading and allows for a more critical examination of each sentence. This technique is often used to improve the overall quality and clarity of the writing.
