Talvez deva tentar algumas variações de ortografia:
basic programming » based programming (Expandir a busca), logic programming (Expandir a busca), conic programming (Expandir a busca)
vpython classes » vpython colisoes (Expandir a busca)
roads decrease » foods decreases (Expandir a busca), goods decreases (Expandir a busca), rate decrease (Expandir a busca)
decrease basic » disease basic (Expandir a busca), decrease asian (Expandir a busca), decreased base (Expandir a busca)
classes java » classes and (Expandir a busca), classes at (Expandir a busca), classes an (Expandir a busca)
code roads » side roads (Expandir a busca), cost roads (Expandir a busca), closed roads (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code roads decrease basic programming ) OR ( vpython classes java python programming ))~.
