I'd use either "carried out" or possibly "run".A machine trial was done on site to prove the new concept.
What word do we useforto say that a trial was 'done' please?
Please suggest a better word instead of using 'prove' the conceptI'd use either "carried out" or possibly "run".
I'm not sure that "prove" is really the right word there.
Who said you can't? The original said "prove a concept".I don't know why you can't test a concept.
No argument intended, but please take a look at this: "Experiments in the 1950s through the 1970s failed to substantiate this concept." (by Hugh McDevitt). And this: "The first such trial was performed by the Medical Research Council on a new tuberculosis medicine, streptomycin, in 1946." (by the St Andrews TB research group)."Performed a trial run" would work.
We don't "substantiate concepts", though. The word normally collocates with "claim/accusation/allegation".
I'd suggest 'performed' or 'conducted'.
I also dislike 'prove' with 'concept' but I can't suggest a better alternative as I don't know what it's supposed to mean.
They used 'carried out' for the word 'trials'.
