In your own words, justify the statement, "oceanic conditions determine human activities."

The statement "oceanic conditions determine human activities" may be interpreted in many ways. 

1. Oceanic conditions determine human activities in that the moon cycle influences the tide. As the moon cycle is said to greatly influence human activity, and the tide changes as the moon does, it may also be concluded that the tides have a similar influence on human activity. 

2. Weather conditions may also influence oceanic conditions.
    a) Hurricanes and typhoons occur in the ocean and if they make landfall, humans are sometimes required to evacuate the location they will affect. The process of evacuation, and the reparations necessary to human civilization afterward, are both examples of oceanic conditions being influential to human activity. 
    b) Flooding and tsunamis may also result in evacuation, and damage to human civilization.
    c) Global warming, which is resulting in the melting of the polar ice caps, contributes to rising sea levels. Rising sea levels are also oceanic conditions that may affect human civilization in the forms of flooding, erosion, and the ocean expanding, and also determine human activities.  

The answer would be c
