Talvez deva tentar algumas variações de ortografia:
rates decrease » rate decrease (Expandir a busca), rats decreases (Expandir a busca), ratio decrease (Expandir a busca)
section rates » infection rates (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code section » code inspection (Expandir a busca), mode selection (Expandir a busca), code detection (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code section rates decrease ) OR ( _ python python python programming ))~.
