We can conclude that Donald is the shortest friend.
<h3>
Who is the shortest?</h3>
This is a logical question, first, we know that the tallest friend will be on the left side, so we assume that the left position can be discarded, so we need to find who is in the right position.
Barry is not in the center and is not the youngest, so Barry is the tallest friend.
Donald is not in the center, and we know that the youngest must be on the right of Adam. So the only position left for Donald is the right one.
Then, we can conclude that Adam must be on the center and Donald on the right extreme. Then Donald is the youngest and shortest friend.

A method which would quickly reveal if the solution was saturated or unsaturated is to add heat to the solution and stir.
<h3>What is solubility?</h3>
Solubility can be defined as a terminology that describes how readily a chemical substance (compound) can be dissolved in a solvent to form a solution, which may either be saturated or unsaturated.
In Chemistry, a chemical substance (compound) is considered to be soluble if it dissolves completely in a solvent such as water.
In this experiment, a method which can be used by the student to quickly reveal if the solution was saturated or unsaturated is to add heat to the solution and stir because it will increase the rate in which it dissolves and settles at the bottom.
