None of the comments I have seen have provided an answer... They have only confirmed that the words do actually sound the same, not provided help on how to disambiguate the sentence. Unless you're saying that there is no way to disambiguate the sentence without further context?
I'm glad my answer was marked correct, it looks like it used to be wrong, not that it is possible to tell from listening. The translation doesn't match my answer because I used the single. Anyway, it would be best if they removed sentences where you can't tell the translation from the context given.
Hi NourAkmenas. Both "Ils" and "Elles" mean "They" but "Ils" is a group comprised totally of Males and "Elles" is a group comprised totally of Females. However do note that if the gender of the group is not known OR there are males in the group, then the article defaults to "Ils". Hope this helps.
None Lurker. They all mean Eat/Eating. The infinitive Manger=To Eat is conjugated and this is addressed elsewhere in this and other threads. You can go to French about.com verb conjugator and type in Manger. There are further links there to learn all about the 3 groups of verbs plus the irregular ones. French verbs are a large part of French language learning.
