Reading Comprehension

In the past decade, rapid technological progress and a greater demand for high-quality digital imaging have led to dramatic advances in video display technology. The dominant technology currently used in most consumer product displays is the active matrix liquid crystal display (LCD).
LCDs apply thin-film transistors (TFTs) of amorphous or polycrystalline silicon sandwiched between two glass plates. The TFTs supply voltage to liquid-crystal-filled cells, or pixels, between the sheets of glass. When hit with an electric charge, the liquid crystals untwist to an exact degree to filter white light generated by a lamp. This filtered light shines directly on the viewing screen or, in the case of projection televisions, is projected through a small chip that acts as a lens. LCDs that are capable of producing color images, such as in televisions and computers, reproduce colors through a process of subtraction, blocking out particular color wavelengths from the spectrum of white light until only the desired color remains. It is the variation of the intensity of light permitted to pass through the matrix of liquid crystals that enables LCDs to present images full of gradations of different colors.
The nature and functioning of LCDs present many advantages relative to other display technologies. The amount of power required to untwist the crystals to display images, even dark ones, is much lower than that required for analogous processes using other technologies, such as plasma. The dense array of crystals displays images from computer or other video graphics sources extremely well, with full color detail, no flicker, and no screen burn-in. Moreover, the number of pixels per square inch on an LCD is typically higher than that for other display technologies, so LCD monitors are particularly good at displaying large amounts of data with exceptional clarity and precision. As a result, LCD TVs are considered the best display platform for video games, high definition television, movie special effects, and other graphics-intensive uses.

The passage indicates that each of the following may be considered an advantage of LCDs relative to other display technologies EXCEPT
they consume less power
they generally have more pixels per square inch of the display
they are able to display continuous video graphics images with no interruption
they reflect a widely adopted standard
they represent the latest, most advanced technology

IMO -- D

D

A) they consume less power (The amount of power required to untwist the crystals to display images, even dark ones, is much lower than that required for analogous processes using other technologies, such as plasma)

B) they generally have more pixels per square inch of the display (the number of pixels per square inch on an LCD is typically higher than that for other display technologies)

C) they are able to display continuous video graphics images with no interruption (The dense array of crystals displays images from computer or other video graphics sources extremely well, with full color detail, no flicker...)

D) they reflect a widely adopted standard (Not mentioned)

E) they represent the latest, most advanced technology (The dominant technology currently used in most consumer product displays is the active matrix liquid crystal display (LCD))

OA is E

This is a specific question that asks us which answer choice is not indicated in the passage as an advantage of LCDs relative to other display technologies. In order to answer this question, one must examine each answer choice and determine if it is mentioned in the passage.

(A) The second sentence of the third paragraph reads, "The amount of power required to untwist the crystals to display images, even dark ones, is much lower than that required for analogous processes using other technologies, such as plasma." The passage indicates that LCDs consume less power than other display technologies.

(B) The fourth sentence of the third paragraph reads, "Moreover, the number of pixels per square inch on an LCD is typically higher than that for other display technologies, so LCD monitors are particularly good at displaying large amounts of data with exceptional clarity and precision." The passage indicates that LCDs generally have more pixels per square inch.

(C) The third sentence of the third paragraph reads, "The dense array of crystals displays images from computer or other video graphics sources extremely well, with full color detail, no flicker, and no screen burn-in." The passage indicates that LCDs can present video graphics images with no flicker or interruption.

(D) The second sentence of the first paragraph reads, "The dominant technology currently used in most consumer product displays is the active matrix liquid crystal display (LCD)." The passage indicates that the technology is a widely adopted standard, which would logically have certain advantages (e.g. the technology has been widely tested and is known to work).

(E) CORRECT. While the passage indicates that LCDs are the result of rapid technological progress in the past decade and the dominant technology currently used, the passage does not indicate that LCDs are the most advanced technology. There may be a more cutting edge technology (e.g. LEDs, or Light-Emitting Diodes) available for certain applications. Also, the passage does not cite any specific functional advantage to being the latest and most advanced.

Don'y you guys thinkl there is too much assumption for the explaination of ans option E. When we are studying this passage we will assume that LCD is the latest and most advanced technology. And if it is the latest and most advanced technology then definitely it has advantage over other technology.

i don't undestand what these type of questions want to test?? sometimes i feel this whole GMAT prep is crap..

I always doubt answers being Not correct, when they have extreme moving words "Most", "Only", "All" etc.

For this passage, there is another question which has me fumbled.

4. The tone of the passage could best be described as
A) supportive advocacy
B)historical discussion
C)objective explanation
D)intellectual exploration
E)qualified support

A)Advocacy is too strong a word here. The author isn't advocating anything. Incorrect
B)There isn't much reference to the past. Incorrect
C) I chose this answer because it was the most neutral. Correct
D) I thought this too be a little too much for the passage. Incorrect
E) Another contender for the correct answer because the author does present his views in the first paragraph and then the remaining two paras support his claim. Unsure

Could someone explain why is option E incorrect here ? Is the author NOT Presenting his views, is it a mere stating of facts ? Which language would the author have used had he been presenting his views / opinions ? Could someone highlight on this point ?

Thank you!

Hi,
option E is incorrect here because the author is not supporting anything related to LCD,he is just intoducing the dominant technology LCD ,explaining its methodology and its advantages over other technology.This whole flow is better considered 'Explanation' rather than 'Support'.Supporting would have been if he would have presented his views to claim LCD as better technology than other existing technologies.
