Talvez deva tentar algumas variações de ortografia:
defense processes » defense process (Expandir a busca), decrease processes (Expandir a busca), disease processes (Expandir a busca)
decrease defense » defense defense (Expandir a busca), decrease release (Expandir a busca), decreases disease (Expandir a busca)
roads decrease » foods decreases (Expandir a busca), goods decreases (Expandir a busca), rate decrease (Expandir a busca)
python task » python based (Expandir a busca)
cost roads » cross roads (Expandir a busca), costa roas (Expandir a busca), forest roads (Expandir a busca)
can python » in python (Expandir a busca), on python (Expandir a busca), and python (Expandir a busca)
task can » task an (Expandir a busca), task in (Expandir a busca), task and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( cost roads decrease defense processes ) OR ( python task can python programming ))~.
