GMAT Sentence Correction Discussions


I will have to go with the smokinskull86 dude on this one.
In the sentence "
since detecting thermal currents are impossible using normal human motion sensitivity". How can "detecting" be an adjective?
I found a simple rule for checking if its an adjective; check this out.



"detecting" is definitely a verb here. And in layman's language it specifies an activity.


Adjective is something which qualify or modify a noun or pronoun. Verb is detect and not detecting, it is a participle which can serve two purpose acting as an adjective as well as verb. After noticing one more time B is also looking as nice option as detecting is acting as Gerund ( noun) here which is a Verb+ ing form and not as adjective.
Apology for my previous post where I refer it as an adjective.

@ Education Aisle, Kindly put your insight to this question.!

kindly post the OA and the source of this question. I myself have some serious doubts about this question.

What I mean to clarify is a "participle" is also a verb in this case "detecting" is a present participle. Implies that "detecting" still remains a verb. The question is "is it describing thermal currents?" as you suggested. My answer would be no. "detecting thermal currents" is just a specific activity the author wants us to know about. If it was "fast thermal currents" or "energetic thermal currents" I would agree that 'fast' & 'energetic' are adjectives here.

Here are the examples-

giggle giggle(s) giggled giggled giggling to giggle

Participles as Adjectives Past and present participles often function as adjectives that describe nouns. Here are some examples:
  1. The crying baby drew a long breath and sucked in a spider crouching in the corner of the crib.
  2. Which baby? The crying baby. Which spider? The one that was crouching in the corner.
  3. The mangled pair of sunglasses, bruised face, broken arm, and bleeding knees meant Genette had taken another spill on her mountain bike.
  4. Which pair of sunglasses? The mangled pair. Which face? The bruised one. Which arm? The broken one. Which knees? The bleeding ones.

Participles as Nouns Present participles can function as nouns-the subjects, direct objects, indirect objects, objects of prepositions, and subject complements in sentences. Whenever a present participle functions as a noun, you call it a gerund.
Take a look at these examples:
  1. Sneezing exhausts Steve, who requires eight tissues and twenty-seven Gesundheits before he is done.
  2. Sneezing = the subject of the verb exhausts.
  3. Valerie hates cooking because scraping burnt gook out of pans always undermines her enjoyment of the food.
  4. Cooking = the direct object of the verb hates.
  5. We gave bungee jumping a chance.
  6. Bungee jumping = indirect object of the verb gave.
  7. Joelle bit her tongue instead of criticizing her prom date's powder blue tuxedo.
  8. Criticizing = object of the preposition instead of.
  9. Omar's least favorite sport is water-skiing because a bad spill once caused him to lose his swim trunks.
  10. Water-skiing = the subject complement of the verb is.

Congrats buddy !!! All the best for apping... :clap:
IMO D

D - "...called for___ and for _____"

A - weird construction
B - not parallel
C - not parallel
E - not parallel

We can eliminate C & E because of another rule.

"Preposition + Noun + Participle" is almost always wrong on GMAT

"with child-care facilities included" - C&E;

B - not parallel. leading neither to....nor a (should be neither to X not to Y)- ELIMINATED
C - not parallel . ...not leading to either ... nor ...(should be either X or Y...) ELIMINATED
D- changes the original meaning. ELIMINATED
E - correct. "not leading to X or Y, nor is it...)
