Question
Initially met with skepticism by her peers in the 1970s, pioneering astronomer Vera Rubin _____ the scientific consensus on the composition of galaxies through her observations of galactic rotation rates, which implied the presence of large amounts of "dark matter" not accounted for in prevailing theories. Her groundbreaking findings have since become widely accepted.

The most logical and precise word to complete the text is (Choice A) "corroborated."
The completed sentence would read: "Initially met with skepticism by her peers in the 1970s, pioneering astronomer Vera Rubin corroborated the scientific consensus on the composition of galaxies through her observations of galactic rotation rates, which implied the presence of large amounts of 'dark matter' not accounted for in prevailing theories."
The word "corroborated" means to confirm or give support to a theory or finding, which accurately reflects Rubin's role in altering the understanding of galactic composition. The other choices do not fit the context as well.
- "Confounded" implies confusion or contradiction, which doesn't align with her confirming findings.
- "Disseminated" means to spread or distribute, which doesn’t fit the context of her findings challenging existing theories.
- "Ameliorated" means to make something better or improve, which doesn't apply to the scientific consensus she was addressing.
Thus, the best choice is (Choice A) corroborated.
