The best way to fill in these two blanks is with the words "manufacturers" and "sellers." The Magnuson-Moss Warranty Act of 1975 requires that these two entities provide consumers with detailed and accurate information about warranty coverage for products being sold. It should be noted that this does not mean that any or all manufacturers or sellers have to provide warranties for the products they make and sell. Instead, the Magnuson-Moss Act is simply meant to ensure that any information or claims made about the warranties are accurate. It is meant to ensure that customers know what their warranties entail, not to ensure that they get any particular level of protection through warranties.
