[amp_mcq option1=”PSRQ” option2=”QRPS” option3=”RQPS” option4=”SPQR” correct=”option4″]
The correct answer is: D. SPQR
Here is a brief explanation of each option:
- Option A: PSRQ
This option is incorrect because it does not follow the chronological order of events. The general death rate in 1948 was the lowest ever recorded up to that date, but this was after the improvement in infant mortality in England and Wales in 1920.
- Option B: QRPS
This option is incorrect because it does not follow the chronological order of events. The improvement in infant mortality in England and Wales in 1920 was after the beginning of the nineteenth century, when improvement began chiefly owing to vaccination.
- Option C: RQPS
This option is incorrect because it does not follow the chronological order of events. The beginning of the nineteenth century, when improvement began chiefly owing to vaccination, was before the general death rate in 1948 was the lowest ever recorded up to that date.
- Option D: SPQR
This option is the correct answer because it follows the chronological order of events. The eighteenth century people expected most of their children to die before they were grown up, but improvement began at the beginning of the nineteenth century, chiefly owing to vaccination. This improvement continued ever since and is still continuing, as evidenced by the general death rate in 1948 being the lowest ever recorded up to that date. There is no obvious limit to the improvement of health that can be brought about by medicine.
