Q1: Easily solved by using the first chart. The continent having the black line more similar to that of Europe is Asia. Answer B.
Q2: Trickier. Let's assume world population is 100 so that we can read the pie chart easily. Then, each percentage is actually equal to the number of inhabitants. Then, we need to estimate from the first chart the amount of electricity and divide it for the population from the pie chart. The highest ratio is the one of North America (Australia is not among the answers). Answer E.
Q3: If South America has a population of 368 mln, then the total population is 368/0.079 = 4658.23. Then, the population of Africa is 4658.23*0.106=493.77 that is rounded to 494 mln. Answer A!

Hi, thanks for this question.
I am unable to get the third one. If I make SA population as 8% (round of 7.9%). Total population is 46 x10^8.
Ten person of this for Africa, answer comes to be ~460 million. For that reason I picked B.
any guidance on why not to pick 8%?
Thanks.
