In the major cities of industrialized countries at the end of the nine

RonTargetTestPrep

I read through the expert answers on this question, but I am still struggling to wrap my head around "but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas" needing to be in the same tense because apparently they occur at the same time.

Thank you for your time and help in advance.

Merely out of inquisitiveness, how places can install electricity?:)
Would it be correct to switch to the passive voice?

important public places such as theaters, restaurants, shops, and banks had installed electric lighting,

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.

(A) electricity was in less than one percent of homes, where lighting was still
(B) electricity was in less than one percent of homes and lighting still
(C) there had been less than 1 percent of homes with electricity, where lighting was still being
(D) there was less than 1 percent of homes that had electricity, having lighting that was still
(E) less than one percent of homes had electricity, where lighting had still been

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.

(A) electricity was in less than one percent of homes, where lighting was still
(B) electricity was in less than one percent of homes and lighting still
(C) there had been less than 1 percent of homes with electricity, where lighting was still being
(D) there was less than 1 percent of homes that had electricity, having lighting that was still
(E) less than one percent of homes had electricity, where lighting had still been

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.

(A) electricity was in less than one percent of homes, where lighting was still
(B) electricity was in less than one percent of homes and lighting still
(C) there had been less than 1 percent of homes with electricity, where lighting was still being
(D) there was less than 1 percent of homes that had electricity, having lighting that was still
(E) less than one percent of homes had electricity, where lighting had still been

In non-underlined part says that -->
important public places had installed electric lighting.
This one is the active sentence. It seems that ''important public places'' took responsibility to install electric lighting! Shouldn't it be an 'authority' who took the responsibility to install electric lighting?

Can I just cross out choice B as it did not used passive sentence. I mean- didn't the highlighted part lost 'be verb'?

My thought:
B--> as there is a complete sentence before AND there should also be a complete sentence after AND. But, there is no independent clause after AND (...and lighting still provided mainly by candles or gas.)

C--> 'where' should modify a 'place', not the 'electricity'.

D--> 'having' should modify whole clause (there was less...) but the 'having' part incomplete itself because of 'that' clause

E--> 'where' should modify a 'place', not the 'electricity'.

Dear Friends,

Here is a detailed explanation to this question-

Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of the crucial part of this sentence is that electricity was in less than one percent of homes, and in these homes, lighting was still provided mainly by candles or gas.

Concepts tested here: Meaning + Tenses + Parallelism

• Any elements linked by a conjunction (“and” in this sentence) must be parallel.
• “where” is only used to refer to a physical place.
• “being” is only to be used when it is part of a noun phrase or represents the passive continuous verb tense; the use of passive continuous must be justified in the context.
• The introduction of present participle ("verb+ing"- “having” in this case) after comma generally leads to a cause-effect relationship.
• Past perfect tense (marked by the use of helping verb "had") is used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past".
• Past perfect continuous tense (marked by the use of helping verb "had/have been") is used when a sentence contains two actions in past and one action is in greater past as well as continuous in nature; the helping verb "had been" is used with the action that is in the greater past and continuous in nature.

A: Correct. This answer choice correctly modifies “one percent of homes” with “where lighting...gas”, conveying the intended meaning – that electricity was in less than one percent of homes, and in these homes, lighting was still provided mainly by candles or gas. Further, Option A forms a complete sentence; the object “lighting” is acted upon by the active verb “was...provided” to form an independent thought, leading to a complete sentence. Additionally, Option A correctly uses the simple past tense verbs “was” and “was…provided” to refer to events that concluded in the past. Moreover, Option A maintains parallelism between the clauses “electricity was in less than one percent of homes” and “where lighting...gas”. Besides, Option A is free of any awkwardness or redundancy.

B:This answer choice leads to an incomplete sentence; the phrase “and lighting still provided mainly by candles or gas” lacks an active verb to act upon the subject “lighting”, as “provided” is a past participle rather than an active verb. Further, Option B fails to maintain parallelism between the clause “electricity was in less than one percent of homes” and the phrase “lighting still provided mainly by candles or gas”; please remember, any elements linked by a conjunction (“and” in this sentence) must be parallel.

C: This answer choice incorrectly refers to "electricity" with "where"; please remember, "where" is only used to refer to physical places. Further, Option C incorrectly uses the past perfect tense verb “had been to refer to an action that concluded in the past; please remember, the simple past tense is used to refer to events that concluded in the past and the past perfect tense (marked by the use of helping verb "had") is only used when a sentence contains two actions in the past; the helping verb "had" is used with the action in the "greater past". Additionally, Option C uses the word “being”, rendering it awkward and needlessly wordy; please remember, “being” is only to be used when it is part of a noun phrase or represents the passive continuous verb tense; the use of passive continuous must be justified in the context.

D: This answer choice alters the meaning of the sentence through the phrase “having lighting that was still...gas”; the use of the “comma + present participle (“verb+ing” – “having” in this sentence)” construction incorrectly implies that less than one percent of homes had electricity because, in these homes, lighting was still provided mainly by candles or gas; the intended meaning is that less than one percent of homes had electricity, and in these homes, lighting was still provided mainly by candles or gas.; please remember, the introduction of the present participle ("verb+ing"- “having” in this case) after comma generally leads to a cause-effect relationship.

E: This answer choice incorrectly refers to "electricity" with "where"; please remember, "where" is only used to refer to physical places. Further, Option E incorrectly uses the past perfect continuous tense verb “had still been provided” to refer to an action that concluded in the past; please remember, the simple past tense is used to refer to events that concluded in the past, and the past perfect continuous tense (marked by the use of helping verb "had/have been") is only used when a sentence contains two actions in past and one action is in greater past as well as continuous in nature; the helping verb "had been" is used with the action that is in the greater past and continuous in nature.

Hence, A is the best answer choice.

Hello aviejay,

Thank you for the PM.

Here are my explanations for your well-articulated queries.




See, it is not that important public places such as theaters, restaurants, shops, and banks all installed electricity at the end of 19th century. These places individually must have installed electricity when they could.

The sentence basically wants to say that at the end of 19th century important public places such as theaters, restaurants, shops, and banks had already started using electricity. So the later event is basically the 19th century coming to its end. Hence, usage of had installed in Choice A is correct.




If the sentence says that lighting had been provided mainly by candle or gas, the usage will suggest that candle or gas was the main source of lighting only till the end of 19th century. After that, they it not used as the source of lighting.

But the sentence just wants to say the opposite. Even after the end of 19th century, majority of homes continued to use candle or gas as the main source of lighting.

Many homes used candle or gas even during the end of 19th century and most likely after that time also. Hence, we need simple past tense verb to denote this general information in the past.




I am not sure why you say so. Don't we say, say after a power outage, that power is back. We all know what kind of entity electricity is.

And again, GMAT SC is not at all about "sounds awkward". It is all about logic that determines the grammar of the sentence.


Hope this helps.
Thanks.
