a) 12 billion
b) 9 billion
c) 6 billion
d) 3 billion

Answer 1

The estimated global population in 2010 was slightly less than 7 billion, as the historical data indicates it reached 7 billion in 2011. Therefore, the closest estimate is 6 billion.

Step-by-step explanation:

To determine the estimated population of humans in the year 2010, we need to refer to demographic data. According to historical population growth trends, by 2011, the global population had reached 7 billion. Given that it was mentioned that adding one billion people has lately taken 12 years, we can estimate that the population in 2010 was slightly less than 7 billion, taking into account a steady growth rate. In the options provided, the closest estimate to this figure would be 6 billion.

Therefore, the answer to the student's question is c) 6 billion.
