second only to Dubai’s Burj Khalifa as the tallest building in the world. A. second only to Dubai’s Burj Khalifa as the tallest building in the worldB. as the tallest building in the world only second to Dubai’s Burj KhalifaC. which, as the tallest building in the world, is only second to Dubai’s Burj KhalifaD. being second in height only to Dubai’s Burj Khalifa as the tallest building in the worldE. second in height to Dubai’s Burj Khalifa only as the tallest building in the world After a quick glance over the options, we have 2 main things we can focus on:
1. second only to / only second to / second in height only to / second in height to only (Idioms)
2. placement of the phrase “as the tallest building in the world” Let’s start with #1 on our list: second only to / only second to / second in height only to / second in height to only. The first thing we can do is get rid of any options that use the phrase “in height.” Why? We already know we’re talking about height because we’re comparing Shanghai Tower to the tallest building in the world, the Burj Khalifa.
This means we can eliminate options D & E because saying “in height” is redundant. Now that we have it narrowed down, let’s determine if there is a difference between saying “second only to” vs. “only second to.” They do mean slightly different things:
X is
second only to Y = Y is #1 overall, and X is #2 overall
X is
only second to Y = Y is not necessarily #1 overall, and X is #2 ONLY when compared to Y – but there may be other versions of Y that it could compare to differently
It makes the most sense to use “X is second only to Y” because it properly conveys the right meaning – that the Burj Khalifa is the tallest building in the world, period – and that the Shanghai Tower is #2 overall. Let’s see how our remaining options handle this:
A.
second only to Dubai’s Burj Khalifa as the tallest building in the world
B. as the tallest building in the world
only second to Dubai’s Burj Khalifa
C. which, as the tallest building in the world, is
only second to Dubai’s Burj Khalifa
There you have it – option A was the correct choice all along. It’s the only one that uses the proper idiom “X is second only to Y” and isn’t redundant.
