Final answer:
The APTA guide is free for APTA members and available to nonmembers through an annual subscription. The correct answer is A. Free; Annual.
Step-by-step explanation:
The guide in question is likely a resource offered by the American Physical Therapy Association (APTA). For members of the APTA, the guide is free, which means that APTA members do not have to pay any additional fee to access the guide. For nonmembers, the guide is available by annual subscription, indicating that they would need to pay once a year to access the guide. Therefore, the correct answer is A. Free; Annual.
The sentence is talking about a guide that is available for APTA members. The word 'free' indicates that APTA members can access the guide without any cost. The word 'annual' suggests that the guide is available for a one-year period.
For nonmembers, the guide can be accessed through a subscription, which is not free. Therefore, option B (discounted; monthly), C (complimentary; biennial), and D (included; lifetime) are incorrect.
