Talvez deva tentar algumas variações de ortografia:
study programmes » study programme (Expandir a busca), study programs (Expandir a busca), study program (Expandir a busca)
decrease study » decrease std (Expandir a busca), increase study (Expandir a busca), decreased steady (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)
python codes » python code (Expandir a busca), python redes (Expandir a busca), python coding (Expandir a busca)
codes java » codes ana (Expandir a busca), codes davi (Expandir a busca), xcode java (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease rate decrease study programmes ) OR ( python codes java python programming ))~.
