Perhaps you should try some spelling variations:
decrease placing » decrease replacing (Expand search), disease placing (Expand search), decreases weaning (Expand search)
placing objects » teaching objects (Expand search), speaking objects (Expand search), flying objects (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their disease » the disease (Expand search), hair diseases (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)

decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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