Question

Ernesto no (leer/oir) el toque del telefono.

Answer 1

ANSWER : Ernesto no oyó el toque de teléfono.

Explanation : The telephone sound has already happened. Then the verb "oir" must be in the past. Oyó => tercera persona singular del pretérito indefinido.

$\textit{\textbf{Spymore}}$​

Answer 2

First, identify the meaning of the words:

Leer - to read.

Oir - to listen.

Since we're taling about a telephone call, the correct option is oir (to listen). But, we do not stop ther since oir needs to be conjugated:

Ernesto no oyó el toque del telefono.
