A) To drain water away from the tracks, railroad beds, like road beds, are designed in which there is usually a bed of rock and gravel resulting in fast drainage from the tracks.
B) Railroad beds, like road beds, are designed in which there is usually a bed of rock and gravel that results in the fast drainage from the tracks.
C) A bed of rock and gravel, called the railroad bed, is designed similar to a road bed to drain water away from the tracks.
D) Railroad beds, like road beds, are designed to drain water apart from the tracks, so there is usually a bed of rock and gravel resulting in fast drainage away from the tracks.

Answer & ExplanationAnswer: D) Railroad beds, like road beds, are designed to drain water apart from the tracks, so there is usually a bed of rock and gravel resulting in fast drainage away from the tracks.
Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms. Atoms are more stable when they have full valence shells.
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period.
HGence, in this trend Francium (Fr) has the lowest ionization energy.
