Understand the definitions of solvent and solute in a solution: the solvent is the component present in the greatest amount, while the solute is the substance dissolved in the solvent.
Recognize that polarity or chemical bonding are not defining characteristics of solvent versus solute; these properties can vary depending on the substances involved.
Recall that the solvent is not necessarily always a solid; it can be a liquid or gas depending on the solution type.
Focus on the key distinguishing factor: the solvent is the substance present in a greater amount than the solute in the solution.
Therefore, the correct completion of the sentence is: 'In a solution, the solvent is present in a greater amount than the solute.'
