Hi debayan, In this construction, we have ellipses at play. Take a look at the sentence with correct answer choice B: As the etched lines on computer memory chips have become thinner and the chips’ circuits (have become) more complex, the power of both the chips and the electronic devices they drive has vastly increased. Because the verb “have become” already appears once in the sentence, it has been kept understood for the second part. With this verb in place, now we have clear clauses. Hope this helps.  Thanks. Shraddha

Shraddha Hi Shradhha, Thanks for the clarification... Few quick qs on it : 1. Is it 650+ or 700+ level qs..? 2.How often we may expect this kind of qs.(where the verb in a clause is kept understood) in GMAT..? 3.How we can tackle or gauge this kind of qs..? Had there been ONLY the 2nd part (i.e. "the chips’ circuits more complex") of the clause starting with 'As', I think we would have required the conjugated verb for sure... Please correct me if I'm wrong. Really appreciate your feedback.

Please correct me if I'm wrong. Really appreciate your feedback. Hi Shradhha/Rajat, Any feedback on this..? Hi debayan, 1. This one is easily a 700 level question. 2. Now ellipsis is quite common in GMAT. Ellipsis can apply to any entity in the sentence, not necessarily only verbs. In comparison sentences, we do witness the understood verbs among other kinds of sentences. 3. You really need to understand the meaning and the context of the sentence to be able to handle such sentences. Make sure that the sentence makes logical sense. Yes, if the sentence were to have only the second part beginning with “AS”, then we would need a verb for the subject. Only those words are made understood in the sentence that have already appeared somewhere in the sentence. Hence, we could keep “have become” understood in the official sentence as it already appears in the sentence. Hope this helps. Thanks. Shraddha

ERROR ANALYSIS:
• From the meaning analysis, we can logically say that the two changes in the memory chips have resulted in increase in the power of the chips. But it is not logical to say that these changes have led to increase in the devices they drive. Increase in the number of devices these chips drive depend on many other factors. Hence, despite being GRAMMATICALLY correct, this choice stands LOGICALLY incorrect.
Thanks.
Hi e-gmat, I basically get stuck in questions where we can infer two possible meanings and this is a classic example of the such scenario. Request you to please clarify my doubt- Reasoning 1 - As you written above. Reasoning 2- It could have been possible that the change in the design could have resulted in the increase of electronic devices. I mean, it could have been possible that earlier microchips are able to pass only 50mA current, but due to new design changes they are able to pass 1000 mA current, and because of this new invention, market is flooded with new electronic devices. Whats wrong in it. How do you make sure which is the intended meaning. Please clarify. Thanks
