Final answer:
Federal Selective Service registration certificates and birth certificates may not be universally acceptable or preferred for age verification for alcohol purchases because of their lack of photo identification and varying state laws.
Step-by-step explanation:
The Federal Selective Service registration certificates and birth certificates are documents that serve specific purposes such as verifying draft eligibility and confirming the date of birth respectively. However, when it comes to verifying the age to purchase alcohol, businesses might be required to check for valid photo identification. Birth certificates do not contain a photo, making it difficult to confirm the identity of the person presenting it. In contrast, Selective Service registration certificates do include a photo but may not always be accepted as a primary form of identification for the purchase of alcohol due to differing state laws and the policies of individual establishments. Therefore, it would be safer to consider the statement false, as these documents may not be universally acceptable or preferred for age verification in alcohol purchases.
