Final answer:
To adjust the width of multiple columns or rows in a spreadsheet, highlight them and double-click the border between any two. Beth's comments about columns refer more to a physical colonnade, not columns in a spreadsheet, while complementary colors are a concept in color theory.
Step-by-step explanation:
To adjust the width of multiple columns or rows at once in a spreadsheet program, you first highlight the columns or rows you want to adjust. Then, you double-click the border between any two of the selected columns or rows. The columns or rows will automatically resize to fit the content, which is useful when you have variably sized data and want a uniform look.
Beth's statement that the columns on the edges are slightly closer than the columns in the center does not typically apply to spreadsheet columns, which are usually uniform unless manually adjusted. Rather, Beth's description sounds more akin to a physical structure with a colonnade, where the colossus might be a massive sculpture nearby. In the world of art and design, complementary colors are used to create visual interest, with each making the other appear more bold—the principle behind this is not directly related to adjusting column widths but is an interesting fact regarding color theory.
