"Anna eats sushi, and so does Dima."
Translation:Анна ест суши, и Дима тоже.
"В какой-то степени каждый из нас Серёжа, а если так, то, должно быть, и я, как другие, тоже немножко Серёжа…" (Е. Клюев, "Между двух стульев" -- https://ru.wikipedia.org/wiki/Клюев,_Евгений_Васильевич)
It’s true, the word order is quite liberal, but... In this case, the order is important, because after the union "тоже" should follow the accented word. In this example, this word is the action "ест" (and not Дима performing the action), and the union "тоже" as part of a complex sentence, means the equality of actions.
You probably got something like this:
- Анна ест суши, как и Дима.
Which is one of the idiomatic ways to express "Anna eats sushi, as Dima does". In spoken speech a simplier "и Дима тоже" (and Dima, too) is more common, I think. However, if you want a longer sentence or a different word order, "как и ..."-structure is more flexible:
- Анна, как и Дима, ест суши, и она знает, о чём говорит. = Anna, same as Dima, eats sushi, so she knows what whe is talking about.
From my understanding, the word а means "and", but really only if you're trying to show contrast. So since they are eating the same thing, you should use и instead. If Anna was eating sushi and Dima was eating rice, then you could write Анна ест суши, а Дима ест рис, because you're showing contrast between what they're eating. Hope that helps.
The suggestions are starting to diverge significantly from the accepted answers. If you had constructed this sentence from the top suggestions, you get «Анна ест суши, поэтому — Дима». Apparently because «поэтому» means "and so" in the sense of "thus". Which is not how it is being used here, so why is it even in the suggestions, much less the top suggestion?
The main reason it would be wrong is because the program wants a literal translation of the English text. But it's also grammatically incorrect because ест is singular. Since two people are eating, you would write Анна и Дима едят since едят is the third person plural conjugation. You'll learn about the other ways to conjugate есть in a later lesson.
