Talvez deva tentar algumas variações de ortografia:
decrease leaming » decreases weaning (Expandir a busca), decreases healing (Expandir a busca), decrease lodging (Expandir a busca)
leaming objects » learning objects (Expandir a busca), naming objects (Expandir a busca), teaching objects (Expandir a busca)
decrease the » decreases the (Expandir a busca), decrease of (Expandir a busca)
the decrease » to decrease (Expandir a busca), and decrease (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease the decrease in decrease ) OR ( decrease NOT decrease leaming objects ))~.
