Final answer:
The statement is false because text that is too long for a cell in word processing or spreadsheet software overflows but stays within the original cell or hides behind content of adjacent cells, unless text wrapping is used.
Step-by-step explanation:
The statement "when text is too long for a row, it spills to the next row" is false. In word processing and spreadsheet software, when the text is too long for a single cell or row, it typically overflows into adjacent cells if they are empty. In spreadsheets, such as Microsoft Excel, the text appears to 'spill' over to the next cell, but it does not actually move into the next row. Instead, the text remains contained within the original cell, and if the next cell is not empty, the overflowing text is hidden behind the content of that cell. Additionally, there are options to wrap text within a cell to prevent such overflow, allowing for all the content to be visible by expanding the cell vertically to fit the excessive text.
