It's a phrase, albeit an awkward one in English. We would normally say "the boys' cats".
they marked my answer with the apostrophe wrong. for duolingo it should be "tge boys cats" -.-
the word bank version of this question is broken, not offering a way to construct the correct answer of " boys' "
I hesitated on that, too. But it accepted it as correct without the possessive apostrophe after 'boys'.
Duo was wrong to accept your answer without the apostrophe as that simply means more than one boy.
The meaning is quite the same. But they are different setences:
The cats belong to the boys = Os gatos pertecem aos meninos
The boys' cats or The cats of the boys = Os gatos dos meninos
The boys' cats. That's how you say it in English.
(The cats that belong to the boys... there is a punctuation error in the answer choices, which makes the correct answer very difficult to deduce/select.)
I am so glad someone spotted and mentioned the punctuation error! I thought I was going to have to read to the end of the comments before mentioning it! Have a lingot!
The boys cats is a phrase; it could answer the question 'who did this?'. But 'The cats belong to the boys' is a complete sentence that stands on its own,and could not really be used as an answer in the same way. Seems a bit unfair, but it is probably Duo's way of helping us to understand about sentance structure... hope my comment helps a bit.
Strange...I wrote "The boy's cats" and was told I was incorrect. I don't understand.
