Great white sharks in Scarborough, Southern ____ are following seals.

The correct answer is Maine because great white sharks have been observed in the waters off the New England coast, particularly around areas like Cape Cod, which is relatively close to Scarborough, Maine. This region is known for having a significant population of seals, which are a primary prey for great white sharks. The increase in seal populations due to conservation efforts has attracted the sharks.

Other options, such as California, while also known for great white shark populations, do not relate to Scarborough, which is specifically in the Southern region of Maine. Florida and Texas are further south and do not typically have the same shark behavior patterns related to seals found in the northeastern U.S., making them less relevant to this question.
