A.I. Explanation:

Option 1: "They rely solely on hunting for food."

Explanation: This option is incorrect because the text states that the Witoto make use of a wide variety of products from the forest, indicating that they do not rely solely on hunting. The phrase 'solely on hunting' suggests an exclusive dependence, which contradicts the broader context provided in the text.

Option 2: "They make use of a wide variety of products from the forest."

Explanation: This option is correct as it directly reflects the text, which states that the Witoto utilize a wide variety of products from the forest. This indicates their diverse use of forest resources beyond just hunting, aligning perfectly with the main idea presented in the text.

Option 3: "They cultivate the forest for agricultural purposes."

Explanation: This option is incorrect because the text does not mention any agricultural practices or cultivation of the forest by the Witoto. Instead, it emphasizes their use of various forest products, which does not imply cultivation.

Option 4: "They are primarily gatherers, not hunters."

Explanation: This option is incorrect as it misrepresents the information in the text. While the Witoto do gather products from the forest, the text highlights that they also hunt, as evidenced by the mention of a tribesman returning from a hunt. Therefore, stating they are 'primarily gatherers' contradicts the text.
