Hi,

the statement talks of four parallel events - follow, look , continue, and return...

so all the 4 should be parallel and similar..
It can be done in two ways-
1) to follow..., to look...., to continue...., and to return - which may not exactly suit here, since all the events follow a sequence as written,..
2) to follow..., look..., continue..., and return.. Correct..

Only A follows the parallelism correctly, while showing proper sequence of activities

D) to follow....,to look....,to continue....,and to return

both are // structures .

Why not D is the answer .

Is it the brevity ?

This question tests the same rule as does question 79 in OG2015. Sometimes parallelism doesn't require prepositions before each element.

I eliminated option A becaz I read somewhere that actions around AND are parallel, for eg. "reading And listening to music" <- this can be performed parallelly. Can we consider 'Return' here with other actions? If yes, is it becaz the context on the expedition plan and not the actual action?

chetan has explained above that all the four are infinitives: to follow..., to look...., to continue...., and to return. So, they are parallel.

"to" is implied in the rest of the three.

Plz. read my qtn. I understand how & why thy are parallel. My qtn - can the actions (literally) be considered executed parallelly?

No, IMO the actions are not considered parallel but sequential.
It's sort of parallelism applied to events that we know will happen sequentially.

I almost made the same mistake. If you look closely, D) is missing to look - it's just look, which destroys the parallelism.

Hi Verbal Experts,
I saw this question on my EP2 today and was unable to figure out correct choice . I wasted my 2 minutes on this and still got it wrong. My confusion is how do I choose between D and A. I chose D over A because I thought "look for ..across the continent" serves as appositive phrase and doesn't require use of "to". Kindly elaborate your approach on choosing correct answer and how to tackle such kind of parallelism based questions which may or may not involve appositive phrases.

Thanks and Kudos for the explanation.

Hi
D doesn't have " to look." In its structure.

D. look for easy water routes across the continent, to continue to the Pacific, and to return.
E. look for easy water routes across the continent, continue to the Pacific, then returning.
Option A is correct
We can set up parallelism with to before each element or to before first element rest of the elements following subsequently.

Pl don't misread parallelism for simultaneity. When you say you want to do A, B, C, and D, you want to do them one after another. An action like ' return' will mean by reasoning that it is the last of the action. The application of sequence is an essential part of the logic of GMAT. After all one can't return before doing these things.

For example,

Ate and slept,
dreamt and danced,
joined the school and failed miserably etc
are all parallel, but can one do the actions of each of the pairs at the same?

Imo A
It correctly maintains parallelism.
E comes close but then returning plays spoilsport.

EMPOWERgmatRichC is this considered a 4-item list? I have never seen one of these... and had thought that any 4-item list would be incorrect.

The Lewis and Clark expedition was to follow the Mississippi to its source, look for easy water routes across the continent, continue to the Pacific, and return.

A. look for easy water routes across the continent, continue to the Pacific, and return.
B. to look for easy water routes across the continent, continue to the Pacific, and then return.
C. to look for easy water routes across the continent, to continue to the Pacific, then returning.
D. look for easy water routes across the continent, to continue to the Pacific, and to return.
E. look for easy water routes across the continent, continue to the Pacific, then returning.

You can see the path to the correct answer in the following way.

Look at the beginning of the sentence.

The Lewis and Clark expedition was to

OK, "was to" what?

follow ..., look ..., continue ..., and return.

A works perfectly.

Let's consider B.

The Lewis and Clark expedition was to follow the Mississippi to its source,

B. to look for easy water routes across the continent, continue to the Pacific, and then return.

We have "to follow" and "to look". So, we need a "to" before each of the other items in the list, but "continue" and "return" do not have "to" before them. So, this list is not parallel.

Let's consider C.

The Lewis and Clark expedition was to follow the Mississippi to its source,

C. to look for easy water routes across the continent, to continue to the Pacific, then returning.

In this version we have a list that has no conjunction. "then" before "returning" does not serve as a conjunction in the way that "and" would in that spot. Also, all of the items in the list except for "returning" are in infinitive form. So, the list is not parallel.

Let's consider D.

The Lewis and Clark expedition was to follow the Mississippi to its source,

D. look for easy water routes across the continent, to continue to the Pacific, and to return.

D is a trap. Because "look" is at the beginning of the underlined portion, It's easy to miss the fact that "to follow", "to continue", and "to return" all include "to", while "look" is alone and is not preceded by "to". Since the elements of the list are all in the same form except for "look", the list is not parallel.

Let's consider E.

The Lewis and Clark expedition was to follow the Mississippi to its source,

E. look for easy water routes across the continent, continue to the Pacific, then returning.

This version almost works. We have "The Lewis and Clark expedition was to

follow ..., look ..., continue ...,"

So far, the sentence works. However, it fails at the end. Rather than a conjunction and another word that works with "was to" we have "then returning". So, we don't have a conjunction to hold the list together, and "returning" does not work with "was to" the way the other three elements of the list do.
