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
thatE)
when the watt-hour rating is higher,
the longer
it isAfter 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 longerB)
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 longerD)
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!
