Zorluk: OrtaVerb Tense, Aspect, and Mood

Although marine biologist Rachel Carson is best known today for her 1962 book *Silent Spring*, her earlier trilogy of books about the ocean—which detailed marine ecosystems with poetic precision—______ her reputation as a pioneering science writer long before that later landmark work sparked the modern environmental movement. Indeed, the commercial success of these early works allowed Carson to resign from her government job and focus entirely on her writing.
