o predict their future【C2】______People seem inclined to【C3】______this task u sing causal reasoning. First, we generally【C4】______that future circumstances are【C5】______caused or conditioned by present ones. We learn that getting an education will【C6】______how much money we earn later and that swimming beyond the reef may bring an unhappy【C7】______with a shark.
