Final answer:
Marie should make the call from Alberta at 12 pm.
Step-by-step explanation:
Marie is an exchange student from Toulouse, France. Toulouse, France is in the Central European Time (CET) zone, which is 6 hours ahead of Alberta, Canada. Therefore, if Marie wants to call her family at 6 pm in France, she should make the call at 12 pm in Alberta. This is because when it's 6 pm in France, it's only 12 pm in Alberta due to the time zone difference.
Therefore,
Marie should make the call from Alberta at 12 pm.
