NO it is not
No the water was dropped, not the cup.correct
A saline solution can be made simply using only water and table salt or sea salt. Simply heat water until it is as hot (but not scalding), and add about about 2 teaspoons of salt per cup of water.
a cup of water that is boiled since it gives more heat.
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
It depends on the size of the cup.
To get a supersaturated solution you can either cool down the solution or let some of the water evaporate. To begin, make some Epsom salt crystals. These are easy to grow and you will begin to see crystals in a couple of hours. Start with one cup of warm distilled water (not boiling).
Saturation is divided into 3 groups: Saturated. Unsaturated. Supersaturated. Supersaturated is when there is too much solute in the solvent so the excess solute just falls to the bottom of the beaker/flask/cup.
Chloride, as opposed to chlorine, is an ion so it can be made by simply putting NaCl (sodium chloride) into water since it is an ionic compound. That means that if you mix salt in a cup of water the salt will dissolve. I'm not sure if you meant chlorine, but that is made industrially by electrolysis of NaCl. Can make NaCl by mixing HCl + NaOH which gives water and NaCl (table salt). If you meant just Cl, well that is a radical. Chlorine is diatomic, and that is made by taking chlorine gas and exposing it to light or heat. It will create a chlorine radical, but these are very reactive and do not just sit around.

True
Salts are the products of reactions between acids and bases (neutralization reactions). A simple example is the reaction: NaOH + HCl = NaCl + H2O
the answer is true not false
There's no reason it should, since the water and the cup fall with the same acceleration.

Water cannot be absorbed into a cup.
It depends because if you put a whole cup of water, then it depends how tall the cup is!
if there was a bag of a hypotonic solution siting in a cup full of water, the water would move into the bag, with the goal of diluting the solute.
