About the Great Lakes of the US

Feature	Details
Definition	The Great Lakes are a series of large interconnected freshwater lakes in eastern and central North America that connect to the Atlantic Ocean via the Saint Lawrence River.
Lakes	Superior, Michigan, Huron, Erie, and Ontario
Location	Generally located on or near the Canada-US border
Hydrological Connection	Lakes Michigan and Huron are connected hydrologically via the Straits of Mackinac.
Significance of Lake Huron	Third largest freshwater lake in the world after Lake Superior and Lake Victoria.
Transportation	The Great Lakes Waterway enables modern water travel and shipping between the lakes.

Significance

The Great Lakes contain a fifth of the world's total fresh water and are a key source of irrigation and transportation. It also serves as a habitat for more than 3,500 species of plants and animals.
Acidification of the Great Lakes Scientists are developing a system that would be able to measure carbon dioxide and pH levels in the Great Lakes over several years.
Increases in atmospheric carbon dioxide are known to have caused the world's oceans to become more acidic.
It was recently observed that by 2100, even the Great Lakes—Superior, Michigan, Huron, Erie, and Ontario—could approach acidity at about the same rate as the oceans. The researchers hope that data from the Lake Huron project will contribute to scientific information on the subject.

About Lake Victoria

It is the second-largest freshwater lake in the world.
It is Located in East Africa on the border with Tanzania, Uganda, and Kenya. It is also called Victoria Nyanza in Kenya, Nalubaale in Uganda, and Ukerewe in Tanzania.
It is the source of the White Nile River, which flows north and eventually joins the Blue Nile in Sudan to form the Nile River.
The lake supports the largest freshwater fishery in the world, producing 1 million tons of fish annually.

Select the correct answer using the codes below:

1, 2, and 3
1, 2 and 4
1, 3, and 4
2 only

Answer: B

Explanation:

Statement 1 is correct: Lake Victoria is the second-largest freshwater lake in the world, after Lake Superior in North America.

Statement 2 is correct: Lake Victoria is located in East Africa, bordered by Tanzania, Uganda and Kenya.

Statement 3 is incorrect: Lake Victoria is the source of the White Nile which flows northward (not southward), eventually merging with the Blue Nile in Sudan to form the Nile River.

Statement 4 is correct: The lake supports the largest freshwater fishery in the world with an annual fish production of around 1 million tons.
