Try your luck with this hand

• Can these resources be combined and legally released as a derivative work?
  • Yes
    • Correct. Resources in the public domain and CC-BY licensed materials can be mixed with the GNU FDL.
  • No
    • Incorrect. These licences are compatible — public domain and CC-BY materials can be mixed with the GNU FDL.
• Which of the following licences could be used for the derivative work?
  • All rights reserved Copyright
    • Incorrect. The GNU FDL (a copy-left licence) requires that derivative works are released under the same share-alike licence.
  • CC BY
    • Incorrect. This would be incompatible with the share-alike provisions of the GNU FDL.
  • Released under a public domain declaration
    • Incorrect.The CC-BY has an attribution requirement. However, attribution is not a legal requirement of resources in the public domain, and the GNU FDL requires modifications to be released under the identical share-alike licence.
  • GNU FDL
    • Correct The derivative work can be released under the GNU FDL, as this would be in accordance with the share-alike provisions of the FDL.
  • CC BY-SA
    • Incorrect. While the BY-SA licence has similar intentions and is ‘philosophically’ aligned with the GNU FDL, the FDL requires that derivative works are released under the same licence. This means that equivalent share-alike licences cannot be used.
  • CC BY-NC-ND
    • Incorrect. Adding more restrictions would not fit with the GNU FDL.
  • CC BY-NC-SA
    • Incorrect. Adding the non-commercial restriction is not permitted by the GNU FDL. In addition, perhaps more importantly, the GNU FDL requires modifications to be released under an identical licence.
