Talvez deva tentar algumas variações de ortografia:
decrease their » decrease the (Expandir a busca), increase their (Expandir a busca), decreases the (Expandir a busca)
decrease actor » decrease after (Expandir a busca), decreased after (Expandir a busca), decreases motor (Expandir a busca)
their disease » the disease (Expandir a busca), hair diseases (Expandir a busca)
decrease rate » decreased rate (Expandir a busca), decreases rate (Expandir a busca), decrease at (Expandir a busca)
rate decrease » rats decreases (Expandir a busca), rate increase (Expandir a busca), to decrease (Expandir a busca)
actor object » action object (Expandir a busca), alter object (Expandir a busca), actor subjects (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease _ decrease their disease ) OR ( decrease rate decrease actor object ))~.
