  • Long-tailed sun skinks are lizards that live in southeast Asia. Most female skinks abandon their nests after laying eggs. But female skinks that live on a particular island with many egg-eating snakes behave differently. These skinks may guard their nests for several days after laying eggs.
  • When female skinks on the island guard their nests, fewer eggs are eaten by egg-eating snakes. If a female is at her nest when a snake approaches, she will attack the snake. Often, she can wrestle the snake out of her nest and away from her eggs.
Why might guarding the nest increase the reproductive success of a female long-tailed sun skink? Complete the claim below that answers this question and is best supported by the passage.
Guarding the nest increases the chances that 
the female will lay more eggs
