The correct answer is A crop failure had led to a famine in Ireland.
The famine is called the Great Famine and caused not only much migration, but also caused many a person's death. That is one of the reason's why there are actually more Irish people in the US nowadays than in Ireland itself.
Remote Sensing
Gis would technically be an okay answer too but in this case Remote sensing best fits.
Answer:
You wouldn't be able to see the planets.
Explanation:
Mercury and Saturn are seen at different times, but still, they're times are totally different than night. You cannot see them at night ever.
The Sun's closest planet is in the evening sky in January, May, September (although barely), and late December. It appears in the morning sky in late February-early March, July, and late October-early November.
Saturn will be at its brightest from August 8 to September 2. Saturn's rings are only visible through a telescope, but the planet itself can still be seen with the naked eye in the mornings through August 1 and in the evenings from August 2 to December 31.
So you cannot see those two planets at night.
