<u>Question 1</u>
The correct answer is: "The world's population would have remained nomadic until these advances were made."
If agriculture and animal domestication had not been developed, human groups would have continued feeding themselves like in the Paleolithic era, by hunting, fishing and gathering. Therefore, once the food and resources in one site had been exhausted, the tribe would have left and sought for a new location where they could continue providing for themselves with the abovementioned activities.
Until human were able to experience technological progress and they learnt how to cultivate and take care of the cattle they were not be able to establish sedentary settlements.
<u>Question 2</u>
The correct answer is: "Consumers in developed nations spend less of their total income purchasing food".
It is in fact the false statement, the one that is not a consequence of modern commercial agriculture. Consumers in developed nations actually demand more products as their income is much higher, so they spend the same or even a larger fraction of the total income, than in subsistence or primitive trading economies.
