Re: Pack 3 Q1 Electricity at first began coming [#permalink]
Electricity at first began coming into houses through direct current because of safety issues created by the high voltage of alternating current, but transformers safely lowered the voltage for use indoors, removing the only advantage direct current had compared to the efficiency of alternating current over long distances.

Ⓐ Electricity at first began coming into houses through direct current because of safety issues created by the high voltage of alternating current, but
Incorrect. Incorrect Comparison: At first and but.. Incorrect Tense: Began

Ⓑ Electricity coming into houses through direct current because the high voltage of alternating current created safety issues, but
Incorrect Tense: Coming

Ⓒ Because electricity came into houses through direct current, since the high voltage of alternating current created safety issues,
Because X, and since - Incorrect. Also personifies electricity and high voltage and does not make sense

Ⓓ At first, electricity came into houses through direct current because the high voltage of alternating current created safety issues, but
Time reference, grammar, tense, logic all maintained - This is correct

Ⓔ While electricity came into houses through direct current, the high voltage of alternating current creating safety issues, but
Introduces contrast with while but then has but - Incorrect
