Talvez deva tentar algumas variações de ortografia:
their programming » their reprogramming (Expandir a busca), theory programming (Expandir a busca), the programming (Expandir a busca)
decrease their » decrease the (Expandir a busca), increase their (Expandir a busca), decreases the (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), ratio decrease (Expandir a busca), rate increase (Expandir a busca)

piton python » pitons python (Expandir a busca), in python (Expandir a busca), with python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease rate decrease their programming ) OR ( python using piton python programming ))~.
