I believe the correct answer is Ayer supe que Luciana se va.
In Spanish, there are some words which indicate which tense should be used. Ayer, meaning yesterday, is one of those words - it is usually used with preterite. So we have to choose between conoci and supe, because both are preterite forms (conocia and sabia are imperfect and should not be used with ayer). Saber means to learn, find out, whereas conocer means to meet someone, or know something. In this case, it's better to use the verb saber and its form supe.
In 1817 the Chilean peso became the country's official currency but remained pegged to (meaning that its value was directly tied to the value of) the Spanish real. However, in 1960 the peso was replaced by a new currency – the escudo. When it was introduced, 1 escudo was worth 1000 pesos.
In Spanish:
En 1817, el peso chileno se convirtió en la moneda oficial del país, pero permaneció vinculado (lo que significa que su valor estaba directamente vinculado al valor) del real español. Sin embargo, en 1960 el peso fue reemplazado por una nueva moneda: el escudo.
