Talvez deva tentar algumas variações de ortografia:
decrease tutoring » decrease during (Expandir a busca), decrease suffering (Expandir a busca), decreased during (Expandir a busca)
tutoring program » mentoring program (Expandir a busca), monitoring program (Expandir a busca), training program (Expandir a busca)
decrease faster » decrease after (Expandir a busca), decrease further (Expandir a busca), decreased after (Expandir a busca)
faster decrease » rate decrease (Expandir a busca)
python java » python data (Expandir a busca), python capaz (Expandir a busca)
java java » java data (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease faster decrease tutoring program ) OR ( python java java python programming ))~.
