Confusion about 802.1x authentication methods

As I read through all materials related to 802.1x, many articles mentioned that "to deploy 802.1x, you'll need to select an authentication method, such as EAP-MD5 and EAP-TLS" (Lisa Phifer) and "802.1x with EAP support multiple authentication methods, such as token cards, Kerberors, one-time passwords, certificates, and public key authentication." (Jim Geier). They are all talking about the "authentication methods" supported by 802.1x and EAP.

It's not clear to me: Does that mean when deploying 802.1x, we can use EAP-MD5, EAP-TLs, token cards, Kerberors, one-time passwords, or certificates as the authentication method? (Some others even call these "authentication types" and make it even more confusing). Or do EAP-MD5, EAP-TLs, etc. and token cards, Kerberors, etc. actually play different roles in 802.1x and EAP infrastructure?
