Yes, both should be given, I'll check it and add it if not. Thanks for the heads up.
How do I tell that the subject is included? It seemed like it was just looked like "eat and drink" to me...
Unless I am mistaken, 'eat and drink' in English can only stand on its own as the imperative, which is very different in Greek. The ending of the verbs here (-ω) clearly indicate it's the first person singular and the phrase means 'I (am) eat(ing) and drink(ing)'.
This is explained in Basic 2 Tips & notes. I've now added it to Basic 1. Each Skill has Tips & note found right under the list of Lessons on the Homepage.
Could you please give more information so we know what you are referring to? We have no way of knowing what your exercise was, what you wrote or what the problem was.
I've completed 3 out of 6 in level 2 of Basics1. So the problem appeared in the third or the second, I think. -- My comment was made under the headline where you put your question, isn't that enough to tell you what I referred to? As far as I can see, it's not possible to return to an old question, so I can't repeat what I did to produce my "error" (I drink and eat, instead of I drink and I eat). To put it in another way: you said "Yes, this is also accepted." I said: "It is not". If you know what you referred to, you also know what I referred to.
When I typed, "I eat and drink", it was marked incorrect. I had to type, "I eat and I drink".
The problem is not the "I" but the fact that it should be:
I drink and eat. ;)
Yes, it's understandable since the usual English is "eat and drink" but we are translating for teaching purposes so need to stick closer to the original.
