Wrong options:

• great: 'Great' implies a large amount, which contradicts the context of insufficient exercise intensity.
• lesser: 'Lesser' suggests a comparative degree but does not convey the necessary threshold concept as effectively as 'minimum.'
• higher: 'Higher' indicates an increased level, which is opposite to what is being stated about sedentary video games.

Correct answer: behaviours
