These questions are from the OG 10. These are the OA with official explanations:
1) A
Choice A, the best answer, preserves grammatical parallelism while allowing for logical expression of temporal relationships; A employs the parallel participial phrases spawned... and extending ... to modify filigree. Other choices present different grammatical constructions that are not participial modifiers and thus not parallel to spawned: extends in B is a present-tense verb; it extended in D begins a new clause; and is extending in E ungrammatically introduces a new predicate. In C, extended is nonparallel if it is assumed to be a past tense 195 verb form; if it is assumed to be a past participle, it illogically states, as does D, that the filigree extended only in the past.
2) B
At issue is the need for logical and formal parallelism in a coordinate series. B, the best choice, clearly and correctly uses parallel noun phrases to list three effects of a drop in oil prices: a lowering of..., a rally in ..., and a weakening of.... In place of the correct lower before/ears, choice A uses an incorrect participial adjective, lowering, that could cause confusion by seeming at first to function as a verb. A also violates parallelism. In C and D, the use of along with confuses meaning by making fears about inflation an independent effect, not an object of lowering. D and E violate parallelism by substituting an awkward gerund clause for the first noun phrase.
3) C
A correct sentence must maintain parallel structure. In choice A, the three-part series (to diagnose ..., deciding,... or other purposes ...) lacks parallelism. C, the best choice, replaces A's third element with/or such purposes as; this phrase functions as a stem for the other two elements, which are recast as two parallel phrases--diagnosing ... or deciding .... Thus, choice C not only manages the parallel structure but avoids the less effective other purposes such as these at the end of choice A. Choice E uses faulty parallel structure (to be used..., deciding ..., or the like). In B and D, which and the use of which introduce sentence elements that lack antecedents or reference. In addition, D is wordy.
1) Presenters at the seminar, one who is blind, will demonstrate adaptive equipment that allows visually impaired people to use computers. (A) one who (B) one of them who (C) and one of them who (D) one of whom (E) one of which
2) Because of the enormous research and development expenditures required to survive in the electronics industry, an industry marked by rapid innovation and volatile demand, such firms tend to be very large. (A) to survive (B) of firms to survive (C) for surviving (D) for survival
(E) for firms' survival
These too are from the OG 10. These are the OA
1) D
The subject, presenters, must be followed by a limiting appositive _ such as one of whom, that identifies an 192 individual from among a larger group. Choice D is best: one of whom best serves an appositive to the subject, presenters, because the phrase means "one from among several or many." Choice A, one who, is unacceptable because one who cannot refer to the plural presenters. Choices B and C are ungrammatical because who competes with one as the subject of is. Choice E employs which, a relative pronoun that does not refer to people (presenters), but only to things.
2) B
The subject of the main clause (such firms) presumes a prior reference to the firms in question. Furthermore, the logical subject of to survive and the logical complement of required should be made explicit. All three demands are met by B, the best choice. Choices A, C, and D, with no reference to the firms in question, meet none of these demands. In choice E, the illogical and awkward use of a prepositional phrase (for firms' survival) buries the needed initial reference to firms in a possessive modifier.

My tries again :) I would go with A. Only A clearly uses the word "both". Both: an acknowledgement and effort to (blah blah). C is out because it uses reducing. Same with E.
2) Using a Doppler ultrasound device, fetal heartbeats can be detected by the twelfth week of pregnancy. (A) Using a Doppler ultrasound device, fetal heart-beats can be detected by the twelfth week of pregnancy. (B) Fetal heartbeats can be detected by the twelfth week of pregnancy, using a Doppler ultrasound device. (C) Detecting fetal heartbeats by the twelfth week of pregnancy, a physician can use a Doppler ultrasound device. (D) By the twelfth week of pregnancy, fetal heartbeats can be detected using a Doppler ultrasound device by a physician. (E) Using a Doppler ultrasound device, a physician can detect fetal heartbeats by the twelfth week of pregnancy.
Will go for E. Sounds more crisp. Uses Active voice. C is out without doubt. After lot of convincing myself, I think, A does not make it clear who detects fetal heartbeats. I couldn't find any other flaw in A. Using something, someone I think is a better construction.
Guys, can someone explain when to use, double instead of twice or two times..what is the difference between them? I get pretty confused when i encounter questions with these.
Guys, can someone explain when to use, double instead of twice or two times..what is the difference between them? I get pretty confused when i encounter questions with these.
Use of Double V/s Twice
Double - It can be used with a Noun / Verb / Adjective / Adverb
e.g.: Noun: 36 is the double of 18 Verb: The population doubled within 50 years. Adjective: An egg with a double yolk Adverb: His eyes were double bright.
Twice is always an adverb. It's usage depends upon the structure of the sentence.
In GMAT twice as much....as, twice as many....as are frequently tested.

1) OA is A. This is the OE (official expln)
Choice A is best. In B, both must come before acknowledgment if it is to link acknowledgment and effort; as misplaced here, it creates the unfulfilled expectation that the reduction of interest rates will be an acknowledgment of two different things. Moreover, both... as well as ... is redundant: the correct idiom is both x and y. In C, the plural verbs acknowledge and attempt do not agree with their singular subject, reduction; also, it is imprecise to characterize a reduction as performing actions such as acknowledging or attempting. In both D and E, the use of the participle reducing rather than the noun reduction is awkward. Like B, D misplaces both, while E repeats both the redundancy of B and the agreement error of C.
2) OA is E. The OE is
Choice A presents a dangling modifier. The phrase beginning the sentence has no noun that it can logically modify and hence cannot fit anywhere in the sentence and make sense. Coming first, it modifies heartbeats, the nearest free noun in the main clause; that is, choice A says that the heartbeats are using the Doppler ultrasound device. Choice B contains the same main clause and dangling modifier, now at the end. Contrary to intent, the wording in choice C suggests that physicians can use a Doppler ultrasound device after they detect fetal heartbeats. In choice D the phrase using ... device should follow physician, the noun it modifies. Choice E is best.
Based on accounts of various ancient writers, scholars have painted a sketchy picture of the activities of an all-female cult that, perhaps as early as the sixth century B.C., worshipped a goddess known in Latin as Bona Dea, "the good goddess." (A) Based on accounts of various ancient writers (B) Basing it on various ancient writers' accounts (C) With accounts of various ancient writers used for a basis (D) By the accounts of various ancient writers they used (E) Using accounts of various ancient writers A patient accusing a doctor of malpractice will find it difficult to prove damage if there is a lack of some other doctor to testify about proper medical procedures (A) if there is a lack of some other doctor to testify (B) unless there will be another doctor to testify (C) without another doctor's testimony (D) should there be no testimony from some other doctor (E) lacking another doctor to testify

A patient accusing a doctor of malpractice will find it difficult to prove damage if there is a lack of some other doctor to testify about proper medical procedures (A) if there is a lack of some other doctor to testify (B) unless there will be another doctor to testify (C) without another doctor's testimony (D) should there be no testimony from some other doctor (E) lacking another doctor to testify
Answer for the 1st one: E A has a dangling modifier. Only the sketchy picture is based on the accounts and not the scholars. B, C, D constructions are roundabout and not right.
For the 2nd question: C choice B is close, but I think it is incorrect because 'will be' changes the sentence to future tense.

The answers are :
1) E. As o-range put it, A suffers from dangling modifier. The others are way out of league.
2) C. In A, 'lack of' doesnt sound idiomatic. In B, the use of future tense disrutps the tense formation. D sounds very formal..(btw is D going into the subjunctive????). In E, lacking disrupts the idiomatic formation.

A dangling modifier is the error well pointed by Sandy...Suppose if we consider "based on xyzw, scholars have painted abcd"
here "based on ...." is the opening modifier phrase, which modifies "scholars have painted..."
however, "based on.." doesnt correctly touch a noun. So we cannot identify which noun it modifies on the basis of given information so it is a dangling pointer (Indian IT Male Syndrome ) oops Modifier.
Now my question, though this seems correct, I am not completely satisfied. Can anyone explain as to why "based on.." Is wrong?
A patient accusing a doctor of malpractice will find it difficult to prove damage if there is a lack of some other doctor to testify about proper medical procedures (A) if there is a lack of some other doctor to testify (B) unless there will be another doctor to testify (C) without another doctor's testimony (D) should there be no testimony from some other doctor (E) lacking another doctor to testify
here (B), (D) can be eliminated because of the tense discrepancies, (E) is very very awkward idiomatically. (A) is also idiomatically wrong because, there is a "lack of " inanimate things, e.g. Lack of oxygen, lack of common sense, lack of money, lack of space, we never say there is a lack of 'engineer' or lack of 'doctor'... Correct me if I am wrong. that's why the answer is (B) it also isn't awkward idiomatically at all.
Friends, can we have some more SC's for which we can practise NOT TO over-correct??

The answer i think should be D. There is clearly a need for a pronoun like 'who'. So the answer should be either D or E. I feel that the subjunctive works well here. So it should be D. In E, 'demanded it to' seems ungramatical.

Sumeet
First Error I can spot is that of Idiom "Consider xyz to be" is wrong. "Consider X Y" is the correct idiom. "question if" is incorrect. So answer seems to be D. where both errors are removed, and statement is grammatically correct with preserved meaning.
(E) is wrong because, "are" doesn't parallel with critics.. xyz.. consider. Grammatically awkward construction. (C) "consider as xyz" is used incorrectly, also the ending clause system, and they question whether makes it ambiguous, and altered intent also (not very sure)
(B) "question if" is incorrect.
fishhhhhhhhhhh.... Such a boring explanation. Would work only if my answer is correct. Let me know brother.... Sooon...

this is the expln,
I think that the answer is A. the idiom is 'consider.....to be'. On those lines i feel the answer should be A.
E is definitely out as 'are' doesnt logically fit in the sentence.
In C, 'as being' is wrong. In GMAT one has to watch out when the word 'being' is used. It is almost always wrong.
In D, 'consider an integral part' i feel is incomplete. I feel that there should be a preposition like 'to be' in between.
In B, i guess that 'they' is not used as a proper referrant. If you consider parallelism, it goes like this.....
..critics consider x........and question y.......
Hence adding a 'they' makes it wrong.
This is my view. Whats the correct answer?
And guys, I got a message while quoting sumeet's question, saying that the message is too short. Please lengthen this message. Did anyone of you get it?
