Hello Everyone!

Let's take a closer look at this question, so we can narrow the options down to get the to right answer quickly! To get started, here is the original question with the major differences between each option highlighted in orange:

Manufacturers rate batteries in watt-hours; if they rate the watt-hour higher, the longer the battery can be expected to last.

A) if they rate the watt-hour higher, the longer
B) rating the watt-hour higher, it is that much longer
C) the higher the watt-hour rating, the longer
D) the higher the watt-hour rating, it is that much longer that
E) when the watt-hour rating is higher, the longer it is

After glancing over the options quickly, it's clear the only thing that's consistent between all the options is the words "higher" and "longer." It also looks like this sentence is attempting to use the following idiomatic structure:

The -er the X, the -er the Y.

For this structure to work, both X and Y need to be written using parallel format.

Since idiomatic structure is an easy way to knock out options quickly, let's see which options follow this format, and rule out those that don't:

A) if they rate the watt-hour higher, the longer

B) rating the watt-hour higher, it is that much longer
(*This sentence also has a vague pronoun "it" in the second half of the phrase.)

C) the higher the watt-hour rating, the longer

D) the higher the watt-hour rating, it is that much longer that
(*This sentence also has a vague pronoun "it" with no clear antecedent.)

E) when the watt-hour rating is higher, the longer it is
(*This sentences also has a vague pronoun "it" with no clear antecedent.)

There you go - option C is the only one that follows the idiomatic structure correctly. If you familiarize yourself with common idiomatic structures, you will find these are some of the quickest to answer!

D the higher the watt-hour rating, it is that much longer that
E when the watt-hour rating is higher, the longer it is


The answers appear to vary significantly, signaling likely Structure, Meaning, Modifier, or Parallelism issues.

Issues

(1) Meaning / Pronoun: they

The pronoun they must be referring to manufacturers (before the semicolon) because batteries cannot rate things. The second
half, then, says: if manufacturers rate [batteries] higher, then the battery will last longer.

The manufacturers could make longer-lasting batteries, but answer (A) implies that simply changing the rating given to a
battery will cause it to last longer. That doesn't make any sense;
the actual battery would have to first last longer in order to
deserve the higher rating. Eliminate answer (A).

(2) Parallelism: higher X, longer Y

The sentence contains a cause-effect structure that needs to be parallel.

(A) if they rate X higher the longer the Y
(B) rating X higher it is that much longer the Y
(C) the higher the X the longer the Y
(D) the higher the X it is that much longer that the Y
(E) when the X is higher the longer it is the Y

Answers (A), (B), (D), and (E) are all wrong; not one offers a parallel structure for X and Y. Eliminate answers (A), (B), (D),
and (E).

The Correct Answer (C) offers the only parallel option: the higher the X, the longer the Y.
