SAT English Practice Question

A new study suggests that while many animals tend to stay in familiar habitats, a particular type of butterfly, the silver-studded blue, is more likely to flourish in new environments. These butterflies are often found in recently formed limestone quarries, which are sites of active industrial activity, rather than in traditional forest areas. The study goes on to say that the silver-studded blue's ability to thrive in these quarries may be because of the lack of predators and the abundance of food in these areas. What is the main idea of the passage?

1. A.is a common type of butterfly.
2. B.may be better suited to living in new environments than in traditional habitats.
3. C.is a species that is often found in limestone quarries.
4. D.is a species that is often preyed upon by other animals.
