We can think of electromagnetic waves as a kind of ongoing message being sent out by the universe. Humans are able to naturally access only a portion of this message. What information from the passage best supports this statement?

a
Mankind has invented tools to harness the information contained within electromagnetic radiation.
b
Without light, we wouldn't be able to process the visible world.
c
The waves emitted by our physical world make it possible for us to communicate over vast distances.
d
The human eye is only sensitive to a portion of the electromagnetic spectrum.

more info ? ? i don't understand what the question is

explanation:

what are the choices?

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
