Markscheme
hinge «joint» ✔

gastrocnemius/soleus is/are the agonist/prime mover ✔
tibialis anterior is relaxing «and acting as the antagonist» ✔
Do not accept isotonic as a sole answer.

Examiners report
Overall a very strong question for candidates with most accurately identifying the hinge joint.
Many candidates were able to identify the movement as plantar flexion. A high proportion of candidates just referred to flexion and identified the muscle; however the question required the specific muscle contraction and this was often omitted in the candidate’s answer.
