Which of the following is not a reason that residents of the new england colonies had longer life expectancies?
a) new englanders traveled infrequently.
b) malaria did not thrive in cold winter climates.
c) residents of new england were more mobile.

The correct options is C.

Explanation:

During the 15th century, many people in America lived in colonies, one of these colonies was New England Colonies. Compare to residents of other colonies, the residents of New England colonies had a relatively higher life expectancy; they usually lived up to 70 years of age.

There are many reasons that are responsible for this, for instance,  the climate that prevailed then at the New England colonies was a cold one that did not favour the spread and survival of mosquitoes, which cause malaria. Also, the people of the colonies do not usually engage in travelling.

Thus, the option C given in this question is not one of the reasons why the residents of New England colonies had longer life expectancy.
