The answer is yes.

In MLA formatting, if your quote is exactly 4 lines or longer, you should format it as a block quote. This means that you should indent the entire quote 1 inch or 10 spaces from the left margin. Here's how you can do it:

1. Start a new line and type the entire quote.
2. Indent the entire quote 1 inch or 10 spaces from the left margin. You can do this by pressing the "Tab" key on your keyboard or adjusting the paragraph settings in your word processing software.
3. Ensure that you maintain double-spacing within the block quote, just like the rest of your paper.
4. Do not use quotation marks around the block quote because the indentation and spacing already indicate that it is a quote.

Additionally, it's important to provide proper citations for any quotes or paraphrased information you include in your paper. For MLA formatting, you should include an in-text citation immediately after the quote to attribute it to the original source. The specific format for the citation will depend on the type of source (e.g., book, article, website) and can include the author's name and a page number or other identifying information.

Remember to consult the official MLA formatting guidelines or a reliable style guide to ensure you follow the correct formatting and citation rules.
