Box Turtles. Suppose you want to know how many box turtles there are in a wooded park. On the first day, you hunt through the woods and capture 18 turtles. You place a spot of paint on each turtle’s shell and release all turtles back where you found them. A week later you return, and with hard work and effort, catch 50 turtles. Of these, 10 are marked and 40 are unmarked. Since you know how many turtles you marked, sampled, and recaptured, you can estimate the size of the whole population. By the definitions above, M =18 marked and released; S = 50 in the second sample; and R =10 recaptures.

explanation:

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
