Final answer:
John Calvin did not contribute to the Renaissance; he was a key figure in the Protestant Reformation, which followed the Renaissance. Key contributors to the Renaissance include Leonardo da Vinci, Johannes Gutenberg, and William Shakespeare. The correct option is O John Calvin.
Step-by-step explanation:
The group that did NOT make an important contribution to the Renaissance was John Calvin. The Renaissance was marked by significant developments in art, science, politics, and theology. Key figures like Leonardo da Vinci made multifaceted contributions as painters, sculptors, scientists, and inventors.
Johannes Gutenberg revolutionized the spread of knowledge with his printing press, which helped disseminate Renaissance ideas widely. William Shakespeare contributed to the Renaissance through his mastery of the English language and literature.
In contrast, John Calvin was a principal figure in the Protestant Reformation, which came after the Renaissance period and was not directly involved in the cultural and intellectual rebirth that characterized the Renaissance.
