What was the purpose of utilizing the 2-back task in Experiment 2?

It was used to measure updating abilities, which are highly critical for simultaneous interpreting because incoming information must be temporarily held and continuously refreshed.

Why might interpreters' language control mechanisms differ from those of other bilinguals?

Unlike typical bilinguals who suppress the non-target language, interpreters must keep both languages highly active in parallel, which may rely less on inhibition.
