Final answer:
The strongest logical counter to parent Q's objection is when similar activities have been conducted safely in the past.
Step-by-step explanation:
The strongest logical counter to parent Q's objection would be option c) Similar activities have been conducted safely in the past.
This counterargument suggests that if similar activities have been conducted safely in the past, it is likely that the proposed activity can also be conducted safely, reducing the potential harm or risk.
For example, if parent Q objects to a school trip to a theme park due to safety concerns, parent P can argue that school trips to similar theme parks have been conducted safely in the past without any incidents, and therefore the proposed trip is unlikely to pose significant risks.
