Arrange the following historical human experiments from OLDEST to NEWEST. A. Finlay and Reed (Mosquito borne nature of yellow fever) B. James Lind (Scurvy) C. Goldberger (Pellagra) D. Edward Jenner (Cow Pox) Choose the correct answer from the options given below:
Historical Experiments Chronological Order
To arrange the historical experiments from oldest to newest, we need to determine the approximate time frame for each discovery:
- B. James Lind (Scurvy): Conducted his landmark study on sailors in 1747.
- D. Edward Jenner (Cow Pox): Developed the smallpox vaccine using cowpox, with key publications around 1798.
- A. Finlay and Reed (Yellow Fever): Carlos Finlay proposed the mosquito theory in the 1880s, and Walter Reed's commission confirmed it in 1901.
- C. Goldberger (Pellagra): Joseph Goldberger's significant research on pellagra occurred in the early 20th century, around 1914-1915.
Experiment Timeline Sequence
Ordering these findings chronologically from oldest to newest yields the sequence:
- James Lind (Scurvy) - 1747
- Edward Jenner (Cow Pox) - 1798
- Finlay and Reed (Yellow Fever) - 1880s/1901
- Goldberger (Pellagra) - 1914-1915
This corresponds to the order: B, D, A, C.
Therefore, the correct option representing this order is the one listing B, D, A, C.
