Final answer:
The statement is true as signing a consent form is needed to show agreement to participate in an activity with potential risks, such as a dangerous rafting trip.
Step-by-step explanation:
The statement that you need to sign a consent form to show that you give your consent for participating in a dangerous rafting trip is true. In many cases, such as those involving research experiments or potentially dangerous activities, an informed consent form is required. This form is essential to ensure that participants are fully aware of the potential risks, implications, and the voluntary nature of their participation. Moreover, it must be affirmed that data collected will remain confidential. Should the participant be a minor, parental or guardian consent is typically mandatory.
