Final answer:
The assertion that the First Folio is the basis for most later editions of Shakespeare's plays is true. Published posthumously in 1623, it has been an essential source for editors like those of Arden Shakespeare and Folger Shakespeare collections.
Step-by-step explanation:
The statement that the so-called "First Folio," published after Shakespeare's death, is the basis for most later editions is true. The First Folio was the first anthology of Shakespeare's plays, published in 1623 by his contemporaries and has served as a crucial reference for subsequent editions of his work. Notably, editions such as the Arden Shakespeare and Folger Shakespeare are widely recognized collections of edited Shakespeare's works, which draw from the First Folio text. It is important to note that Shakespeare himself never published any of his plays during his lifetime, a decision made to avoid the potential for other companies to access and perform his work without permission.
The First Folio included an engraving by Martin Droeshout, which, along with the memorial bust of Shakespeare at Holy Trinity Church in Stratford, were approved by people who knew Shakespeare and are regarded as two authentic likenesses of the playwright.
