Hey there! I'm happy to help!
Let's look at the answer options.
A. farmers require minimal land to feed the population.
B. people are able to leave agriculture for different fields.
C. fewer farms are needed to feed the population.
D. more people depend on factory-made food.
E. farmers lack workers to support their farms.
We can immediately eliminate answer D. All food still originates from farms and agriculture. It is like factories have some magical machine that creates bread from nothing; you get the wheat from the farmers to make it!
Answer A does not make sense because it is saying they don't need much land to feed the population, but not needing a lot of land is good because if more land is taken up it really doesn't matter, so this hypothetical is more of a pro than a con.
Answer C can also be eliminated because because if there is a higher population you need more farms to make more food for more people.
Now, it is between B and E. Agricultural density is how many farms or farmers there are per unit of arable land. So, our answer has to do with a number. Answer B has to do with people leaving agriculture for different fields, resulting in a smaller number of farmers. E is saying that there won't be enough workers. But that isn't a number. It doesn't have to do with the actual density.
Therefore, the answer is b) people are able to leave agriculture for different fields.
Have a wonderful day! :D
