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 fear » decrease after (Expandir a busca), decrease cell (Expandir a busca)
fear decrease » break decrease (Expandir a busca), merr decreases (Expandir a busca), can decrease (Expandir a busca)
python using » python coding (Expandir a busca), python usando (Expandir a busca), action using (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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