To correctly punctuate compound adjectives in the provided text, you would add hyphens where necessary to ensure clarity and accuracy. Let's review the text and identify where hyphens should be inserted:
1. "full length sculpture" - should be "full-length sculpture"
2. "Greek Slave" - does not require hyphens
Therefore, the corrected text with hyphens inserted for compound adjectives is as follows:
"Hiram Powers started his career as a sculptor by creating wax figures in a museum, but in 1843 he achieved fame with a full-length sculpture called The Greek Slave."
