In the 1980s, in response to concern over dependence on foreign oil, france nearly tripled its use of nuclear energy. what reduction in environmental pollution from the electric power system did france experience during this time?

The correct answer is - around 80%.

With the big concern during the 1908's about the oil reserves and how much longer will they last, France was very concerned about the energetic future of the country, thus it invested a lot into the building of nuclear plants.

Apart from building nuclear plants in its own territory, France also built multiple nuclear plants on the territory of French Guiana in South America. With this, France managed to produce its own energy, and even have surplus and sell it to other countries.

The changes in the pollution levels were also significant, because they dropped for around 80% according the official estimates, which is excellent, and just shows that if most of the countries used this method for production of energy the environment can be preserved and kept in good shape.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
