The full question is this: Early humans had access to different kind of foods depending on the local geography. If a group lived in the interior of the continent, what would they least like have at meal time? 
The correct option is FISH AND SHELLFISH.
The interior of the continent are made up largely of inland areas which are majorly lowlands. The annual range of temperature in interior of the continent is always very high, this implies that only specific plants can grow in the area. Water bodies are not present in continent interior, that is why, it is unlikely for those living there to be eating fish and shellfish. Fish and shellfish can only be enjoyed by those living in the coastal areas.
