technology et » technology e, technology ecit, technology eimt
et selection » en selection, test selection, sex selection
costs some » cost some
prices et » prices pt, prices _, prices 3

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "technology et selection _ ((prices et) OR (prices a)) communication costs some development case 2.~".
• Adding a wildcard symbol may retrieve word variants: technology et selection _ ((prices et) OR (prices a)) communication costs some development case 2.*.
