listened: the wild life of jane goodall: chapter 2

• jane observed chimps capturing termites, showing that chimps and humans are more different than scientists had realized.
• jane was regularly attacked by the chimps while she lived among them, showing that they are far more vicious than humans.
• jane was befriended by the chimps while she lived among them, showing that they can show generosity, like humans.
• jane observed chimps using tools, showing that chimps and humans are more alike than scientists had imagined.

Explanation:

To solve this, we analyze each option based on Jane Goodall's research:

• Option 1: Her research showed similarities, not more differences. Eliminate.
• Option 2: She wasn't regularly attacked; this misrepresents her work. Eliminate.
• Option 3: While chimps can show generosity, her key finding was tool use, not mainly generosity. Eliminate.
• Option 4: Jane Goodall observed chimps using tools, which challenged the view that tool use was unique to humans, showing chimps and humans are more alike than previously thought. This matches her research.

Answer:

D. Jane observed chimps using tools, showing that chimps and humans are more alike than scientists had imagined.
