ANSWER
True.
Step-by-step explanation
Leptons are any elementary subatomic particles that cannot be affected by strong force but are affected by electromagnetic, weak and gravitational forces.
Quarks are any elementary subatomic particles that interact by means of the strong force.
All matter (atoms et. al.) are made up of leptons (e.g. electrons) and quarks (such as protons made up of quarks).
Therefore, the answer is True.
