Passage Summary: Crocodiles in Lake Victoria are attacking people much more often than they used to, even though there aren't more crocodiles and they still have plenty of fish to eat.

Reasoning: The frequency of crocodile attacks on humans has risen over two decades, yet the crocodile population size and the availability of their natural prey have remained stable.

Analysis: This is a classic paradox where we have an effect (more attacks) without the most obvious causes (more crocodiles or less food). To resolve this, we need to find an external factor that changed in the last 20 years. Look for an answer that introduces a new variable, such as a significant increase in the human population using the lake or a change in human behavior that puts them in closer contact with the crocodiles.
