Incomplete question. However, I inferred you are referring to May 14, 2015, theconversation online article by Manu Saunders a Post-doctoral Research Fellow (Ecology), at Charles Sturt University.
<u>Explanation:</u>
The article stresses the consequences of single-crop farming on wildlife survival in other to allow for biodiversity. Specifically, she focuses on the impact of single-crop farming on wild pollinators such as native bees and hoverflies.
Therefore, according to Manu's research, this pollinators have restricted access to diverse resources as a result of single-crop farming; which leads us to the central theme; Single-Crop Farming Is Leaving Wildlife With No Room To Turn.
Out of the choices given, in order to become more efficient and to make greater profits, both individuals and nations learn to specialize. The correct answer is D.
Explanation:
Well I would suggest you to look at the key words and ask some questions to yourself like;
"What emotions is White Fang feeling?"
"What things did he do mostly in the passage?"
I don't tell straight out answers but I hope this helps <3
