Talvez deva tentar algumas variações de ortografia:
replication challenges » application challenges (Expandir a busca), applications challenges (Expandir a busca), education challenges (Expandir a busca)
challenges decrease » changes decrease (Expandir a busca), challenges case (Expandir a busca), challenges because (Expandir a busca)
coded replication » based replication (Expandir a busca), code application (Expandir a busca), codes application (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code coded » code code (Expandir a busca), gcode code (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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