“Manufacturers rate batteries in watt-hours; if they rate the watt-hour higher, the longer the battery can be expected to last” - is a GMAT sentence correction question. These types of questions contain grammatical errors in the underlined sentence, and we have to choose the correct statement from the options. GMAT sentence correction is part of GMAT verbal.

Answer: C
Explanation:

To validate the phrase's desired alteration, the tenets listed below can be used:

  • Parallelism
  • Examining two separate aspects
  • Modifiers

This is how the sentence is put together:

Option A is incorrect:
A is the proper response. The main focus of the comparison is the women's ages. Therefore, I guess we should keep (A) and see whether there is something better elsewhere.

Option B is incorrect:
The inappropriate response is B. That might sound acceptable, but it's complete nonsense: (B) claims that the BABIES were born before the age of thirty. Sure, kids are obviously younger than thirty, but that is not the point being made by the text. (B) gives us: "...more babies were born to mothers over the age of thirty than born under the age of thirty."

Choice C is correct.
This is the best option. The ideal choice is this. The causal relationship that the text alludes to is clearly stated by the adverbial conjunction because. The singular verbs severs and is as well as the singular subjects cut and less suitably modify countable fibres.

Choice D is incorrect.
This is the incorrect option since, in accordance with the timeline, one past perfect tense event must occur before another simple past event. That "children were born to women over the age of thirty" CAME AFTER "there had been" infants born to women under the age of thirty is therefore nonsensical.

Choice E is incorrect.
This is the incorrect move to make. The past perfect tense in this situation makes no sense, therefore even if (E) sounds great, it is inaccurate for the same reason that (D) was.
