What proved to be a major hardship for settlement in the New England colonies? Trading with neighboring colonies. Exporting raw materials to England. Creating the shipbuilding industry. Developing agriculture during hot summers.

The correct answer is "Exporting raw materials to England".

Explanation:

One of the opportunities that New England colonies struggled to achieve was the chance to export their raw materials to England. England's government had very strict policies in the introduction of materials to its country. The New England colonies had limited options of materials to export (limited to tobacco, sugar, rice, molasses and furs) and all of them should pass the English's port custom.
