Perhaps you should try some spelling variations:
financial liabilities » financial viability, financial stability
financial activities » financing activities, microbial activities, financial securities
general activity » neural activity, gene activity, genetic activity
central activity » mental activity, cultural activity, neural activity

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((financial activities) OR (financial liabilities))) OR (((general activity) OR (central activity)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((financial activities) OR (financial liabilities))) or (((general activity) or (central activity))))".
• Adding a wildcard symbol may retrieve word variants: ((((financial activities) OR (financial liabilities))) or (((general activity) or (central activity))))*.
