What of the listed observations the flowing?
Select one:
a. Birth rate
b. study of growth of 15 year-old boys for 12.01.2015
c. Results of population census
d. Morality during a year
e. Results of routine inspection
The answer is :
b. study of growth of 15 year-old boys for 12.01.2015.
Because of
1. Generally,we are not list out the Birth rate,results of population census, results of routine inspection and mortality during a year
2. We are study oneo by one growth of 15 year-old boys for 12.01.2015
