Uranium is mined in Niger to produce electricity. The residents of Niger are concerned because uranium mining produces cancer causing radioactive wastes that enter the groundwater they drink. The table below shows the number of cancer patients in the Niger mining community between 1958 and 1974.

Year Number of cancer patients

1958 9

1962 10

1966 14

1970 46

1974 59

Based on the table, which of these is the most likely year when uranium mining was first done in Niger?

a-between 1958 and 1962

b-between 1962 and 1966

c-between 1966 and 1970

d-between 1970 and 1974

Based from the given data of the number of cancer patients in the Niger mining community between the years 1958 and 1974, the most likely year when Uranium mining was first done in Niger was between 1970 to 1974. This claim is supported by the fact that there was a 228% increase in the number of cancer patients from 1966 and 1970. This increase is significant and alarming, especially when we consider the presence of Uranium mining in the community. The given data can prove that radioactive wastes have indeed entered their groundwater supply and induced cancer among the residents.
