Answer: stage 2.
Explanation:
When we are talking about the theory that involves the comparison of infant death rates and birth rates then, what comes into mind is the demographic transition. Demographic transition has 5 stages which includes the following;
(1). Stage 1 : where the infant death rate and birth rates are high and the natural increase is stable.
(2). Stage 2: where we have the death rate falling rapidly and an increase in the birth rate.
(3). Stage 3: where the birt rate falls and the death rate also continue to fall.
(4). Stage 4 : both the birth rates and the health rates are low.
(5). Stage 5: at this stage the death rate is still low and the birth rate increase.
From the question; Country x has a crude birth rate of 40 and a crude death rate of 15. The birth rate increases,that is 40 and the dealth rate is low, that is 15 for the Country which means that the country's demographic transition is STAGE 2.
GPS is a system made up of three parts (satellites, ground
stations, and receivers) that help in determining ground location with
incredible precision. The satellites continuously transmit a signal and its
receiver calculates its distance from the satellite. The positions of the
satellites are used by the receivers as reference points to determine the
location of the GPA receiver.
For instance, when a hiker gets lost in the woods and has
access to a GPS receiver, he will easily be able to determine his current
location. Marking his starting location on a GPS receiver will also assist him
into finding his way back.
