Answer:

  (a) The number of births is equal to the number of deaths from 2007 to 2013

Step-by-step explanation:

Given a graph of population versus time that is roughly flat from 2007 to 2013, you want to know the most likely characteristic of the population.

Change

The population is shown as being 58 in 2007 and 56 in 2013, representing a decline of 2 individuals.

Births and immigrants will increase the population. Deaths and emigrants will decrease the population.

The graph has no direct information regarding any of these: births, deaths, immigrants, emigrants.

Relationships

When the population remains steady or slightly declining, there must be a balance between increases (births and immigrants) and decreases (deaths and emigrants). Of the offered answer choices, the best description is ...

  The number of births is equal to the number of deaths from 2007 to 2013
