The question is saying that Elena attended so it is past tense<span> and because it is referring to Elena it will be el/ella/usted conjugation.
Therefore: it is probably </span><span>asistió which means attended.
It could be ha </span>asistido though because ha <span>asistido means has attended but Elena has attended a conference does not sound as good as Elena attended a conference.
</span>
1: abierto
2: comida
3: roto
4: leido (the last one)
