Final answer:
The quiz question about the type of scientist Bettye Washington was cannot be answered due to a lack of information on a scientist by that name. The passage instead describes the differences in the work between biologists, chemists, and astronomers.
Step-by-step explanation:
The question 'What type of scientist was Bettye Washington?' does not correspond to any widely recognized scientist by that specific name, and therefore it is not possible to accurately categorize the type of scientist Bettye Washington was. However, the passage provided talks about the nature of scientific work for biologists, chemists, and astronomers. It outlines the differences between laboratory-based scientists and those who study cosmic phenomena, such as astronomers, whose “laboratory” is the universe itself. The passage instead describes the differences in the work between biologists, chemists, and astronomers.
