Objectively, of course, the various ecosystems that sustain life on the planet proceed independently of human agency, just as they operated before the hectic ascendancy of Homo sapiens. But it is also true that it is better or worse, been substantially modified by human culture. Nor is this simply the work of the industrial centuries. It has been happening since the days of ancient Mesopotamia. It is coeval with the origin of writing and has occurred throughout our social existence. And it is this irreversibly modified world, from the polar caps to the equatorial forests, that is all the nature we have.
Consider each of the three choices separately and select all that apply.


It can be inferred from the passage that the author would agree with which of the following statement?

  A Overtime the impact of human culture on the natural world has been largely benign.
  B It is a mistake to think that the natural world contains many areas of pristine wilderness.
  C The only substantial effects that human agency has had on ecosystems have been inadvertent

[Reveal] Spoiler: OA
B


The author mentions " ancient Mesopotamia " primarily in order to

A provide some geographical and historical contend for an earlier claim about the ascendancy of Homo sapiens
B support the idea that the impact of human culture on nature was roughly the same in the ancient world as in later times
C identify a place where the relationship between culture and nature, was largely positive
D emphasize, the extent to which the modification of nature by human culture preceded the industrial period
E make a connection between the origins of writing and other aspects of human cultural development

[Reveal] Spoiler: OA
D

Explanation

1) The answer is B. A nd C have a positive impact on the ecosystem. i.e. human beings over the centuries didnt have a huge or significant impact on the ecosystem. Instead, is the contrary. They have had and still have. So the answer is B

2) Clearly is D. Since the time of Mesopotamia, the humans started to modify the natural environment.

But, the "right" answer D of the the second question requires outside information-- information outside of the passage. I would have chosen answer D if it had not mentioned the word extent. The emphasis -- extent requires specification, which is absent in the passage unfortunately.

The underlined red part shows you the extent. So, D is correct
