Beard's and Jones's inventions both improved existing designs.
Solución
To emphasize a similarity between Beard's invention and Jones's invention, we need to focus on how both inventions improved upon existing designs.
Let's analyze the options:
(A) This statement only discusses Jones's invention and does not mention Beard's invention, so it does not highlight the similarity.
(B) This statement only discusses Beard's invention and does not mention Jones's invention, so it also does not highlight the similarity.
(C) This statement effectively highlights the similarity by stating that both Beard's automatic coupler and Jones's mobile refrigeration system improved on existing designs. This directly addresses the goal of emphasizing a common aspect of both inventions.
(D) This statement contrasts the two inventions rather than highlighting a similarity, as it focuses on what each invention specifically enabled without connecting them.
The best choice that effectively uses relevant information from the notes to emphasize a similarity between Beard's and Jones's inventions is:
**(C) Beard's automatic coupler and Jones's mobile refrigeration system both improved on existing designs.**
