I introduce two objects and need to tell how we refer each of the objects further in the text. How is it better to formulate it? Is the following correct:
There are two person in the study. We refer to one person who works a lot as "hard-working" and another as "lazy".
Sorry for such a profound example. :)
Update: I modified the example such that the terms characterising each person is not self-explanatory.
There are two persons in the study. We refer to one person who works a lot as P1, and another as P2.
The questions are:
1) Is it grammatically correct?
2) Is it concise and clear? If not, what should be the structure of the sentense?
