In order to answer these questions, you must look at the geographical differences that lead to different objectives and colonies for the Spanish and British Empire. In Southern America, there was an abundance of golds and silvers in the region, which lead to Spain to have a desire for investing in metals and silvers. There was little focus or concentration in other resources in New Spain, and these mines were not focused at all on long term investment. Also, the Spanish colonies had strong Spanish authority and influence, making the colonies extraction to get the most profit out of them and the land. This hurt most South American nations when they became independent as they possessed very weak infrastructure with little knowledge of self independence.
The British colonies in North America originally were set up to find gold as well but to no fortune. Even though Britain did create profits through certain cash crops like tobacco, the colonies for the most part relied almost independently on themselves at first. This is especially true for those leaving for religious purposes, such as the Pilgrims or Quakers. This created a reliance for the British colonists to take care of themselves, which in turn began to develop their own economies over time and quickly develop political independence.

Answer:
They can lead to the lifting of sanctions.
Explanation:
Aid doesn't help an economy.
Competing with the United States is more like a result of having a developed economy, rather than a cause of an economy developing. Plus, the United States wouldn't likely export the same things as a developing nation.
International trade agreements don't help an economy to 'grow quickly', plus this is a really general answer.
The lifting of sanctions is really important. It's hard to develop under sanctions. Trade agreements allow for the regulation, reduction and removal of sanctions. For example, if the US made a trade deal with Mexico, it would greatly help Mexico to develop, as they would now be trading more freely with the United States.
