Hi
KarishmaBI have learnt that Verb-ing without a comma modifies the noun or noun phrase just before it. But here in option B, the word cutting should modify electrification of lightening, but it's modifying work efficiency. Isn't option B incorrect too?
Posted from my mobile device thereisaFirePresent participle (verb-ing) without a comma when used as a modifier modifies the preceding noun or noun phrase. Here, 'cutting' is not being used as a modifier. It is a part of the subordinate clause starting after the subordinating conjunction 'while.'
Electrification doubled efficiency while cutting energy costs...Electrification doubled efficiency - main clause
while cutting energy costs... - subordinate clause (a reduced adverbial clause)
"While" is a subordinating conjunction and gives adverbial clauses. It shows simultaneous action and uses progressive.
A happened while B was happening.
When both, the main clause and the subordinate clause, have the same subject, we can skip the mention of the subject and the be verb in the while clause.
...the electrification ... doubled work efficiency while electrification was cutting energy costs in half.
becomes
...the electrification ... doubled work efficiency while cutting energy costs in half.
Both doubling and cutting was done by "electrification" so we don't need to use it again.
So (B) is correct.
