The question seems simple but so far I do not have a response. I'm wondering how to avoid the following type of repetition :
adjective1+ noun or adjective2 + noun
For instance (2 examples) :
1- "..a green car or a red car"
2-"It corresponds to a lower bound change or an upper bound change"
Here "car" and "change" are repeated twice. Can we change that to
1- "..a green or red car"
2-"It corresponds to a lower or an upper bound change"
It looks like we are loosing something by this reformulation.
