Question

—Do you know the transportation system in London? If you know your friend's address, your smart phone can guide you through the fastest route. (1 point)

saber, conocer

conocer; saber

Answer 1

- Conoces el sistema de transporte en Londres? Si sabes la dirección de tu amigo, tu teléfono inteligente/celular/móvil (smartphone) puede guiarte por el camino más rápido.

Step-by-step explanation:

I chose "conoces" in the first phrase because "conocer" is used when talking about knowing an object, place or person while "sabes", chosen in the second phrase, is used means to know a fact or something.

I'd recommend revising the difference between saber and conocer.
