"Su" and "sus" in Spanish both mean "his," "her," "its," "their," or "your (formal)." The difference between "su" and "sus" depends on what comes after -- whether it is singular or plural. It does not matter whether the "owner" of the object is singular or plural. "Trabajo" is singular, so you can only say "su trabajo." If you want to use "sus" it would have to be "sus trabajos."
It does fit, and Wobzter, so does "show". And many will argue show would be muestran and the students are presenting would be "Los estudiantes están presentando". But meanings overlap, and the progressive form is used, but a lot less in Spanish. Think of a native Spanish speaker trying to use the progressive and saying "I am being sick today". It works. It just sounds a little funny. Should it be added as an answer? I think so, but only going from Spanish to English.
Another meaning of presentar is "to introduce". I do not understand why "The students introduce their work" is not accepted. Can't you introduce work?? I've been in classes where one had to introduce one's project to a class.
Can someone help me understand why this was rejected??
you can present something by describing it in detail, or you can present something by unveiling it and saying 'ta da here it is.' This second meaning is similar to submit.
In the question, since there's so little information about what's going on, why not just go with the obvious and answer it as "presentar" = "present?"
No, there is no confusion. It has been said multiple times in the comments that when there is a su or a sus, it always refers back to the person or persons already mentioned, with no further explanation. If in fact, the su or sus refers to someone else, it will be explained further, with something like... el trabajo de él... or de ella.
No, way. "Su" and "sus" can always mean all the things Allan noted. And the sentence "The students present his work" makes perfect sense. Say the students have set up a display of Picasso's paintings. They are presenting his work. Thus, they present his work.
Or say, there is a composer who's music is being played by a string ensemble. "They present her work.
Also... "su" or "sus" does not relate back to anything in the sentence and no matter how many times anything was said in the Comments. All pronouns are established at the beginning of a conversation and remain as they are up to the point something else gets named. This applies to "su" in this sentence.
If nothing was being talked about other than the students, nothing named, such as Picasso, then the default meaning of "su" would relate to the students. But since we just got into the room and missed out on what's being talked about, we can't know or assume what "su" means for sure. So what we most need to do, as students, ourselves, is learn all the possible usages of "su" as it is used in this sentence.
You have probably improved your English spelling since you posted this, but it should be "their, not "thier" and "were," not "where," jimbo-m.
Also, it probably depends on whether each student submitted his own work and all of them submitted it at the same time. Or, it could be that all students worked on one assignment and submitted it collectively at the same time. A native Spanish speaker could probably explain the distinction and how to say it. Anyone?
Though I entered 'present', I initially read the sentence as 'The students turn in their work'. Assuming the context does not contradict it, are there any issues with this interpretation; is the a better way to give the implication of turning in an assignment as opposed to presenting it? Present gives the implication that you are giving it directly to your professor, while turn in can mean a direct submission, it can also mean, for example, that the work is being placed in a receptacle designated for assignments.
"Los/las estududiantes presentan su trabajo" gets the definite article because the noun "students" refers to "students in general.
However, the rule is the opposite in English. When speaking of "students in general," no definite article is needed. In fact, if you use "the" before "students in an English sentence, then you are indicating that the number of students is countable.
With an audio-only clue, unless there are adjectives or other words to clarify feminine versus masculine, Dúo should accept either "los" or "las." Distinguishing between these with no other clue or context is unnecessarily difficult with these poor quality audio snippets.
