2. I disagree.

4. OK.

5. Probably B.

26. OK.

It can only be D then but I don't think they consider salt water a resource..?

-MC

2. is D.

To answer question 2, we need to locate the information about the water resources of Earth. This information can be found in various sources such as textbooks, scientific journals, or reputable websites. One possible approach is to search for information on the distribution of water resources on Earth. By examining sources that discuss freshwater sources, saltwater sources, and the distribution of water in different forms, we can determine the correct answer. In this case, option C is the correct answer as it includes freshwater found in rivers, lakes, and streams, along with the other sources mentioned.

For question 4, we need to understand the difference between weather and climate and find the accurate definition. Reliable sources such as textbooks or reputable climate organizations can provide the necessary information. By comparing the definitions of weather and climate as provided in the options, we can determine the correct answer. In this case, option D is the correct answer as it accurately describes climate as the overall pattern of weather recorded over a period of years.

For question 5, we need to evaluate the given options and determine the environmental impacts of using pesticides. Reliable sources on pesticide use and its effects can provide the necessary information. By considering the impacts listed in the options and understanding the potential effects of pesticides, we can identify the exception. In this case, option B is the correct answer, as the use of pesticides does not generally increase the variety of crops, but rather focuses on controlling pests that can harm crops.

For question 26, we need to understand the possible effects of burning fossil fuels and their contribution to certain environmental issues. This information can be found in sources such as scientific reports or reputable environmental organizations. By considering the options and understanding the link between burning fossil fuels and the mentioned issues, we can identify the correct answer. In this case, option C is the correct answer, as burning fossil fuels can increase the levels of carbon dioxide in the atmosphere.
