Answer:
d) The answer is impossible to determine from the given information
Step-by-step explanation:
One might think that the correct answer is the b) it rose. However, you should consider that the statement is comparing the lifestyle of humans 1000 years ago with modern standards of poverty. Which is not entirely correct, since 1000 years ago antibiotics had not been discovered, nor had processes developed to purify water, much less invented means of transport such as train or cars. It is possible that 1000 years ago, lacking these comforts wasn't an indicator of poverty as it is today, basically because at that time in history those things didn't exist.
