Answer:
British settlements in the New World began as chartered colonies primarily for trade purposes and developed rapidly. However, many settlers came for social reasons as well, especially to seek religious freedom. In the beginning, governance was left to colonial assemblies. However, Britain became more involved in colonial affairs after it received Canada in the Treaty of Paris. In general, British settlers had little contact with American Indian groups, and early settlers tended to keep to themselves. Of Britain’s 13 original colonies, the northern colonies developed as early centers for manufacturing and trade, while the southern colonies developed as centers for agriculture. Slave labor was used extensively to work the tobacco and cotton fields. The French were motivated by exploration and trade. Their initial goal was to find a route to the Pacific Ocean. French traders established outposts in Canada and along the Mississippi River. Fur was greatly desired in Europe, and there was good money in the fur trade. French settlements grew slowly because their primary purpose was as trade outposts. Unlike the English colonies, which were comprised of various religions, the French colonies were Roman Catholic by law. The French settlers in Canada had very good relations with American Indians, perhaps because they were so reliant on them for the fur trade. French settlers often learned American Indian languages and customs. French holdings in the Caribbean were different; the French used massive amounts of slave labor to work the plantations. In Haiti, for example, slaves outnumbered white colonists eight to one.

Sample Response
The statement is - True.
The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.
The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy.
