One group of students is investigating the cause of the unusual color of water in wells of a location. they analyze the land surfaces and gather data about the locations of the polluted wells. what should be done to ensure that their results are reliable and valid? (1 point)
match the results with secondary sources
get the results approved by government agencies
publish the results in newspapers and magazines
share the results with others who can repeat the study

Option B, Get the results approved by government agencies

Explanation:

The findings of the student can be verified by someone who has already conducted research or studies in the same field earlier. Since a government agency would have carried out a sincere study and their findings would be more accurate as compared to any of the secondary sources, newspaper or magazine publication, it would be advisable to get the results verified by some government agency.

Also a finding attested by a government organization is more trusted than its verification from any other sources.  

Hence option B is the correct choice of answer

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
