while researching a topic, a student has taken the following notes:\n• in 1897, african american inventor andrew beard invented an automatic coupler.\n• it improved on the existing design of train car couplers.\n• it made the job of connecting train cars safer.\n• in 1938, african american inventor frederick jones invented a mobile refrigeration system.\n• it improved on the existing design of food transport trucks.\n• it enabled trucks to carry perishable foods farther.\nthe student wants to emphasize a similarity between beards invention and joness invention. which choice most effectively uses relevant information from the notes to accomplish this goal?\nchoose 1 answer:\na joness mobile refrigeration system, which he invented in 1938, made it possible for food transport trucks to carry perishable foods farther.\nb in 1897, beard invented an automatic coupler, which made the job of connecting train cars safer.\nc beards automatic coupler and joness mobile refrigeration system both improved on existing designs.\nd beards invention made the job of connecting train cars safer, whereas joness invention enabled food transport trucks to carry perishables farther.
Answer
Brief Explanations:
We need to find the option that emphasizes the similarity between Beard's and Jones's inventions.
- Option A only talks about Jones's invention.
- Option B only talks about Beard's invention.
- Option D emphasizes the differences (safer connecting train cars vs. carrying perishables farther).
- Option C states that both inventions "improved on existing designs", which is a similarity as per the notes (Beard's improved train - car couplers, Jones's improved food transport trucks).
Answer:
C. Beard’s automatic coupler and Jones’s mobile refrigeration system both improved on existing designs.
