Roger is at a wedding reception where he has been introduced to over 50 guests whom he has never met. He would like to remember as many names as possible.

 The 3 primary memory levels are encoding, storing, as well as retrieval.

1. Encoding threshold: This threshold will assist Roger to receive, procedure and combine information.

Encoding would allow knowledge (identities) to enter your senses during your wedding reception in the context of physical and chemical stimuli.

2. Storage Level: This level would allow Roger to build a permanent archive of encrypted data (names). It will allow him to keep up with details across time.

3. Retrieval level: This proportion should allow Roger to recall information stored (names) in answer to any prompt for use in a system or method.

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
