Answer:
<em>(A) the estimated population
</em>
Explanation:
The best way to deal with this is to avoid the plural pronoun ' their, ' which has no place in this sense as we're talking about the rhino (a singular) group.
Therefore options B and E are removed.
In terms of ' amount ' we do not quantify a population. Therefore, option C is also removed.
In D the estimation of population is odd.
<em>The correct version is the projected population. A is the right choice.</em>
The correct answer is letter B. The method of ranking social status that asks people to rank themselves is called subjective method. This is where people are asked to rate themselves and their current status in society. This is a common practice used in surveys performed by many governments around the world.
The second choice because if you build a lake before building houses then the lake will tear apart the houses.
