- Volcanic ash in the atmosphere decreases the temperature by blocking the sun
- Emitting sulfur dioxide causes acid rain
- An erupting volcano releases sulfur gas and ash into the atmosphere
- So, a volcanic eruption can cause acid rain and decrease the temperature

- A volcanic eruption can cause acid rain and decrease the temperature
- Europe was unusally cold and had acid rain in 1783
- Therefore, a volcanic eruption may have happened to cause the cold weather and acid rain in europe

- The statement "Astronauts require preserved food for extended flights" is irrelevant

Therefore, a volcanic eruption may have happened to cause the cold weather and acid rain in europe
In 1783, Europe was unusually cold and foggy. The rain was acidic. Which event most likely caused the unusual climate in Europe that year?
- Astronauts require preserved food for extended flights
- Volcanic ash in the atmosphere decreases the temperature by blocking the sun 
- Europe was unusally cold and had acid rain in 1783 
- Emitting sulfur dioxide causes acid rain 
- An erupting volcano releases sulfur gas and ash into the atmosphere
