The use of gravity waves, which do not interact with matter in the way electromagnetic waves do, hopefully will enable astronomers to study the actual formation of black holes and neutron stars.

(A) in the way electromagnetic waves do, hopefully will enable
(B) in the way electromagnetic waves do, will, it is hoped, enable
(C) like electromagnetic waves, hopefully will enable
(D) like electromagnetic waves, would enable, hopefully
(E) such as electromagnetic waves do, will, it is hoped, enable


Pls give explanation.
HOPEFULLY is always wrong in GMAT
reject A,C,D
we are left with B and E ,here E is wrong such as EM wavs do is wrong .such as idiom is followed by examples hence do will be hanging the without any referrent.
B is the best choice among the lot
IMO B
OA pls !! :) :?:

Dear Friends,

Here is a detailed explanation to this question-
Curly05
The use of gravity waves, which do not interact with matter in the way electromagnetic waves do, hopefully will enable astronomers to study the actual formation of black holes and neutron stars.


(A) in the way electromagnetic waves do, hopefully will enable

(B) in the way electromagnetic waves do, will, it is hoped, enable

(C) like electromagnetic waves, hopefully will enable

(D) like electromagnetic waves, would enable, hopefully

(E) such as electromagnetic waves do, will, it is hoped, enable


Meaning is crucial to solving this problem:
Understanding the intended meaning is key to solving this question; the intended meaning of this crucial part of this sentence is that it is hoped that the use of gravity waves will enable astronomers to study the actual formation of black holes and neutron stars.

Concepts tested here: Meaning + Comparison + Idioms + Awkwardness/Redundancy

• A comparison must always be made between similar things.
• “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples.
• "hopefully" means "full of hope" and not "it is hoped"; for this subtlety, please be very careful when you see "hopefully" in an answer choice; it is generally incorrect.

A: This answer choice alters the meaning of the sentence through the phrase "hopefully will enable"; the use of the adverb "hopefully" to modify "will enable" illogically implies that the use of gravity waves will carry out the action of enabling astronomers in a hopeful manner; the intended meaning is that it is hoped that the use of gravity waves will enable astronomers; remember, "hopefully" means "full of hope" and not "it is hoped". Besides, the placement of “hopefully” is such that it doesn’t directly modify the verb “enable”; “will hopefully enable” would have made Choice A more competitive. On a side note, the term “hopefully” is generally incorrect on GMAT as it often suffers from such imperfect adverbial usage issues.

B: Correct. This answer choice uses the clause "it is hoped" to modify the verb "enabled", conveying the intended meaning - that it is hoped that the use of gravity waves will enable astronomers. Further, Option E correctly compares the clauses "interact with matter" and "electromagnetic waves do". Additionally, Option B avoids the idiomatic error seen in Option B, as it uses the phrase "in the way" rather than "like" to draw a comparison. Besides, Option B is free of any awkwardness or redundancy.

C: This answer choice alters the meaning of the sentence through the phrase "hopefully will enable"; the use of the adverb "hopefully" to modify "will enable" illogically implies that the use of gravity waves will carry out the action of enabling astronomers in a hopeful manner; the intended meaning is that it is hoped that the use of gravity waves will enable astronomers; remember, "hopefully" means "full of hope" and not "it is hoped". Further, Option C incorrectly compares the clause "interact with matter" to the noun phrase "electromagnetic waves"; remember, a comparison must always be made between similar things. Besides, the placement of “hopefully” is such that it doesn’t directly modify the verb “enable”; “will hopefully enable” would have made Choice C more competitive. On a side note, the term “hopefully” is generally incorrect on GMAT as it often suffers from such imperfect adverbial usage issues.

D: This answer choice alters the meaning of the sentence through the phrase "would enable, hopefully"; the use of the adverb "hopefully" to modify "will enable" illogically implies that the use of gravity waves will carry out the action of enabling astronomers in a hopeful manner; the intended meaning is that it is hoped that the use of gravity waves will enable astronomers; remember, "hopefully" means "full of hope" and not "it is hoped". Further, Option D incorrectly compares the clause "interact with matter" to the noun phrase "electromagnetic waves"; remember, a comparison must always be made between similar things. Additionally, Option D redundantly uses the verb "would" alongside the adverb "hopefully"; remember, “will” is preferred for referring to events that are certain to happen, and “would” is preferred for referring to events that are hypothetical, meaning the use of “would” alongside words that express uncertainty is redundant.

E: This answer choice incorrectly uses the phrase “such as” rather than “as” to compare the clauses “interact with matter” and “electromagnetic waves do”; remember, “like” is used for comparing nouns, “as” is used for comparing actions/clauses, and “such as” is used for giving examples.

Hence, B is the best answer choice.

To understand the concept of "Like" vs "As", you may want to watch the following video (~2 minutes):



All the best!

A. in the way electromagnetic waves do, hopefully will enable

B. in the way electromagnetic waves do, will, it is hoped, enable

C. like electromagnetic waves, hopefully will enable

D. like electromagnetic waves, would enable, hopefully

E. such as electromagnetic waves do, will, it is hoped, enable


SC21561.01


I always don't understand this point of grammar. Gravity waves do not interact with matter like electromagnetic waves. Clarify on what this means, I think it means it does not interact with matter that is like electromagnetic waves.

Gravity waves do not interact with matter like electromagnetic waves do interact with matter.

Do you cut out the "interact with matter" part to make it more readable. Is that what people do who speak English?

You have to understand stuffed bears are foreigners like someone from Russia or India. :lol: :lol:

Official Explanation

Rhetorical Construction; Diction

While the use of hopefully, as used in the sentence as written, to mean I hope that or let's hope that, is well established, this use is considered to be informal. For this reason, it is generally avoided in writing.

When it is used in this way in writing, however, it must be used at the beginning of a sentence or at the beginning of an independent clause, and be set off by the use of commas. In any case, the use of hopefully in this sentence is incorrect: in a technical sense, it implies that the enabling of the astronomers will be hopeful.

A. The use of hopefully here is incorrect, for the reasons given above.

B. Correct. The use of it is hoped (as opposed to hopefully) here properly conveys the intended meaning of the sentence. Furthermore, the use of in the way appropriately conveys, unlike the answer choices using like or such as, that what is being compared is the interaction, or lack thereof, of gravity waves, on one hand, and electromagnetic waves, on the other, with matter.

C. The use of like incorrectly implies that electromagnetic waves are a type of matter. Furthermore, the use of hopefully is incorrect, for the reasons given above.

D. The use of like incorrectly implies that electromagnetic waves are a type of matter. Furthermore, the use of hopefully is incorrect, for the reasons given above.

E. The use of such as is inappropriate here: first, such as must be followed by a noun, or list of nouns, rather than a noun followed by a verb, as in electromagnetic waves do; second, the use of like incorrectly implies that electromagnetic waves are a type of matter.

The correct answer is B.

(B) is right. Technically, the word "hopefully" is an adverb form of the word "hopeful," which is used to describe one's state of mind about a particular thing.

For example:

JP is hopeful that he will get a good score on the GMAT.
JP thought hopefully about his future GMAT score.

But:

JP will, it is hoped, receive a high score on the GMAT.

or:

It is hoped that JP will receive a high score on the GMAT.

Thats right! Hopefully is almost never correct as per GMAT standards. The answer option B looks the best, as option E has a wrong such as usage.

Why hopefully is wrong in GMAT??? any reason..

hopefully is adverb modifies enable... looks perfect.

On second look, C and D are out because improper comparision.


which do not interact wiht matter like EM waves
= G waves .. interact wiht matter like EM waves.
(comparing "G waves interact" with "EM waves") --> C and D are out

Between A and B.
I am not conviced why hopefully is wrong..

hi x2suresh
check out this link which talks about incorrect usage of hopefully.

https://grammar.quickanddirtytips.com/hopefully.aspx

hopefully ,this link helps ... :shock: oops
i hope ,this link helps :-D
do check out this too :
https://dictionary.reference.com/browse/hopefully

hopeful cannot be paralleled with i hope
hopefully means certainly (a sort of making prediction)
"Hopefully, I will win the Nobel Prize in Literature." -> incorrect this is kind of statement in which the person is unsure
“Hopefully, I will win the Nobel Prize in Literature, irregardless.” -> correct -> the person is hopeful

i hope u got the meaning y hopefully is incorrect usage in geneal when used for meaning "i hope or it is hoped "

(A) in the way electromagnetic waves do, hopefully will enable
'hopefully' is acting like a sentence adverb..modifying entire sentence...But, adverbs should modify only verbs..use of hopefully is not correct here.
(B) in the way electromagnetic waves do, will, it is hoped, enable
hold it
(C) like electromagnetic waves, hopefully will enable
comparing an action with a subject
(D) like electromagnetic waves, would enable, hopefully
comparing an action with a subject
(E) such as electromagnetic waves do, will, it is hoped, enable
such as is used to illustrate a set of related items. its usage is not correct.

Thanks spriya and everybody...

I pick B because I look at your question about Will.

I was really torn between A, B though.

After reading this by BlindVision, I'm a bit more clear now:

"This once-useful adverb meaning "with hope" has been distorted and is now widely used to mean "I hope" or "it is to be hoped." Such use is not merely wrong, it is silly. To say, "Hopefully, I'll leave on the noon plane" is to talk nonsense. Do you mean you'll leave on the noon plane in a hopeful frame of mind? Or do you mean you hope you'll leave on the noon plane? Whichever you mean, you haven't said it clearly. Although the word in its new, free-floating capacity may be pleasurable and even useful to many, it offends the ear of many others, who do not like to see words dulled or eroded, particularly when the erosion leads to ambiguity, softness, or nonsense."

A is eliminated because of the incorrect usage. On GMAT, we generally try to avoid the word "hopefully" especially when it is not acting as a clear adverb and is used in place of " I hope that"
For example, "Hopefully, he will reach my place by noon"
Here, Hopefully is incorrectly used. Rather, it should have been I hope that...
I

in option (B) isn't 'it is hoped' redundant?

Redundant means something already used and repeated needlessly. Where has 'it is hoped' been used already in B or for that matter any other choice?

On the contrary, the issue with 'hopefully' is more problematic. Can we precisely say who is acting hopefully? It cannot be said that the use of gravity waves or the waves are acting hopefully. The 'it' in 'it is hoped' is a filler. Therefore, that use is passable.

A. in the way electromagnetic waves do, hopefully will enable
B. in the way electromagnetic waves do, will, it is hoped, enable
C. like electromagnetic waves, hopefully will enable
D. like electromagnetic waves, would enable, hopefully
E. such as electromagnetic waves do, will, it is hoped, enable

The first entry point is the use of the adverb ''hopefully' which goes against the vibe and the ethos of GMAT. For whatever reason, GMAT has not approved that word. So we can boldly remove A, C, and D.
Between B and E, the meaning is completely warped in E; B is the answer

Only A & B come close to a valid answer choice. Between A & B, A uses hopefully incorrectly.

Here is what ROn said about hopefully in another official question.

Generally "Hopefully" is incorrect on GMAT, whenever we stumble upon it, ask who is hopeful. If we can get the answer, then only we can use it

So B is the answer.
