A teacher has stated that "measured" in the following sentence is not the past simple of the verb "measure". Do you agree or disagree with him? How should we infer this?
The essential challenge is to devise a single operational and trading framework that can accommodate traditional thermal-generation plants (large, inflexible units with slow ramp rates and lead times measured in hours), intermittent renewable plants (with unpredictable power fluctuations on time scales measured in minutes), and hydroelectric or other flexible plants (which help to integrate the other two generation types but have limited capacity and possibly high cost).
Bahareh MA teacher has stated that "measured" in the following sentence is not the past simple of the verb "measure". Do you agree or disagree with him?
Bahareh MHow should we infer this?
By the grammatical pattern. A preposition (on) cannot take a sentence as its object (time scales measured in minutes).
on time scales measured in minutes
(time scales which were measured)
with the baby found in the forest
(the baby which was found).
'measured in minutes' modifies 'time scales', just as 'found in the forest' modifies 'the baby'. In both cases the modifier is a participial construction.
It is typical to omit the relative word (which) and a form of be in these constructions.
And by the meaning. Time scales cannot measure anything, so it doesn't make sense to say that in the past they measured in minutes.
The meaning is that the someone (not the time scales) measures something (power fluctuations) in terms of minutes.
