Explanation:

Normal 0 false false false EN-US X-NONE X-NONE This was essentially a vocabulary question - you need to know or guess the meaning of Anthropogenic. Anthropogenic means ‘caused or produced by humans’.
From the second paragraph, “…anthropogenic drought resulting from deforestation, by soil nutrient depletion and other soil problems, and by the struggle to prevent bracken ferns from overrunning the fields.”
Option 1 is incorrect because lack of rain cannot be attributed to human intervention.
Options 2 and 3 are incorrect because they are reasons to the causes of the drought and why the drought was anthropogenic.
Option 4 means the same as anthropogenic. Deforestation and soil nutrient depletion can only be caused by humans.
Option 5 is incorrect because a drought caused by climate changes cannot be said to be caused by humans.
Hence, the correct answer is option 4.
