Question

Increased IMR and decreased MMR in a population will

• A. cause rapid increase in growth rate
• B. result in decline in growth rate
• C. not cause significant change in growth rate
• D. result in an explosive population

Answer 1

The correct option is C

not cause significant change in growth rate

The correct option is C:

Explanation of the correct option:

Option C:

1. IMR is known as the infant mortality rate.
2. It is the number of deaths per live birth of children under one year of age.
3. MMR is known as the maternal mortality rate.
4. The MMR can be calculated by dividing the recorded death of mothers by the total number of recorded births in the same period of time and then multiplying it by 100,000.
5. An increased IMR and a decreased MMR do not a significant change in the growth rate.

Explanation of the incorrect options:

Option A:

1. An increase in IMR does not cause a rapid increase in the growth rate.
2. The growth rate does not increase upon a decrease in MMR.
3. Thus, this is an incorrect option.

Option B:

1. The growth rate won't be significantly decreased due to an increase in IMR and a decreased MMR.
2. This is not the correct option.

Option D:

1. The increase in IMR would not cause an explosion in population growth.
2. The decrease in MMR has no effect on the explosion of the population, therefore this is an incorrect option.

Final answer: Increased IMR and decreased MMR in a population will result in a decline in the growth rate.
