OG13 Practice Questions - Q99

by fermar84 » Wed Aug 27, 2014 6:48 pm
The stars, some of them at tremendous speeds, are in
motion just as the planets are, yet being
so far away
from Earth that their apparent positions in the sky do
not change enough for their movement to be observed
during a single human lifetime.
(A) The stars, some of them at tremendous speeds,
are in motion just as the planets are, yet being
(B) Like the planets, the stars are in motion, some
of them at tremendous speeds, but they are
C) Although like the planets the stars are in motion,
some of them at tremendous speeds, yet
(D) As the planets, the stars are in motion, some of
them at tremendous speeds, but they are
(E) The stars are in motion like the planets, some of
which at tremendous speeds are in motion but

Why like is used to compare stars and planets, I thought that like was only used to compare people?
When would you say it is correct to use Like and when to use As?

Thanks,
FM

Hi Fermar,

'Like' is used to COMPARE NOUNS, whereas
'AS' is used to Describe NOUN's function

Hi fermar84,

When dealing with "comparison rules", you must be sure to compare "like" things. The word "like" is not restricted to just comparing people.

eg.
Like John, Mary enjoys jogging.
Like walking, jogging is a physical activity.
Like John's walking style, Mary's walking style is brisk.
etc.

When dealing with a comparison at the beginning of a sentence, the GMAT tends to use the word "like." However, the entire sentence still needs to be grammatically correct, so seeing a comparison written in this style (at the beginning of a sentence) is not necessarily enough to select an answer.

The correct answer B presents a proper comparison and makes no mistakes in the modifiers and pronoun it uses.

The word "as" doesn't mean much by itself. It's often used as a "2-part" phrase (eg. AS many apples AS bananas) or to reference an example (e.g. a piece of fruit SUCH AS an apple).

Hello Everyone!

Let's tackle this question, one issue at a time, and narrow it down to the correct choice! First, let's take a closer look at the original question and highlight any major differences between the options in orange:

The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

(A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being
(B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are
(C) Although like the planets the stars are in motion, some of them at tremendous speeds, yet
(D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are
(E) The stars are in motion like the planets, some of which at tremendous speeds are in motion but

After glancing over the options quickly, a few key differences pop out that we can focus on:

1. yet being / but they are / yet / but (Coordinating Conjunctions)
2. placement of the phrase "some of them at tremendous speeds" (Modifiers/Meaning)
3. just as the planets are / like the planets / as the planets (Idioms/Comparisons)


Let's start with #1 on our list: coordinating conjunctions! Whenever we see coordinating conjunctions as one of our key differences, we MUST check to see that they are being used properly. Coordinating conjunctions (for, and, nor, but, or, yet, so) can only be use to connect 2 independent clauses. Let's take a look at each option to figure out if they are using conjunctions correctly. (I've added the non-underlined portion of the sentence to help see the problem.)

(A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

independent clause + yet + dependent clause = WRONG

(B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

independent clause + but + independent clause = OK

(C) Although like the planets the stars are in motion, some of them at tremendous speeds, yet being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

independent clause + yet + dependent clause = WRONG

(D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

independent clause + but + independent clause = OK

(E) The stars are in motion like the planets, some of which at tremendous speeds are in motion but being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

independent clause + but + dependent clause = WRONG (This is also missing a comma before the conjunction "but.")

There you go - we can eliminate options A, C, & E because they don't use coordinating conjunctions properly!

Now that we have it narrowed down to only 2 options, let's take a closer look at each one and see if we can find any problems:

(B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are

This is the CORRECT choice! The preposition "like" should always be used after a noun, which it is here.

(D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are

This is INCORRECT. The word "as" should only be used as a conjunction to join two clauses together. Since the phrase "As the planets" isn't a clause with a subject and verb, this doesn't work.


There you have it - option B is our correct choice!


Don't study for the GMAT. Train for it.

in choice a, "some of them at tremendous speeds" work ad adjective , modifying "stars". this phrase dose not closely related the the meaning of the sentence. this point is hard to realize.
if correct adverbial phrase (choice b shows) is changed into adjective phrase, we do not realize easily that the new adjective phrase dose not closely relate to the whole meaning of the sentence. we can say that the new adjectival phrase is not integrated closely into the sentence. this error of meaning is hard.

in B, "some of them at tremendous speed" work as an adverb , well modifying "stars are in motion" . this is good.

if the opposite case happens. the correct adjectival phrase is changed into adverbial phrase, we can easily realize that the new adverbial phrase incorrectly modify the clause.
