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 diode 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 LCD displays to present images full of gradations of different colors.
The nature and functioning of LCD displays 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 burnin. Moreover, the number of pixels per square inch on an LCD display 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 graphicsintensive uses.
Q.
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
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
In the past decade, rapid technological progress and a greater demand ...
This is a general question that asks about the tone of the passage. In order to answer this question, it is useful to briefly examine and summarize the respective paragraphs.  
Paragraph 1: LCDs have become the dominant display technology in the past decade.
Paragraph 2: LCDs function by channeling electricity to untwist crystals to block light in order to form colors.
Paragraph 3: LCDs present advantages relative to other display technologies, particularly for certain uses.  
The correct answer will effectively identify the tone adopted in these paragraphs.
(A) It is too strong to categorize the author's tone as "advocacy," as the first two paragraphs are purely explanatory. The third paragraph, though listing advantages of LCD displays, does not advocate their use.
(B) Although the first paragraph does mention the time frame and context of the development of LCD displays, neither the second nor third paragraph could be classified as part of a historical discussion, and no contrast is drawn. Thus, it would be inaccurate to characterize the tone of the passage as that of a historical discussion.  
(C) CORRECT. The passage objectively explains the background, functioning, and advantages of LCD displays. 
(D) The passage does not indicate any questioning, skepticism, or exploration in its text, and is more technical than intellectual in tone.
(E) Although one could argue that the passage implicitly approves of the development of this new technology, the passage does not advocate for a particular point of view, and there is no evidence of any qualification in its explanation of the functioning and advantages of LCD displays.

Disruptive innovators can hurt successful and immensely profitable incumbents that tend to ignore the markets most susceptible to disruptive innovations. Disruptive innovators offer technologically straightforward solutions consisting of off-the-shelf components put together in a product architecture that is often simpler, initially lower performing, and cheaper than established approaches. Considering disruptive technologies unprofitable, the executives at incumbents often ignored them at their own and companies peril. In 1981, the old 8 inch drives used in mini computers were vastly superior and much more profitable to the new 5.25 inch drives used in desktop computers. However, 8 inch drives were not affordable for the new desktop machines. Slowly, the makers of 5.25 inch drives improved the performance of the drives and moved the 8 inch drive companies that did not invest in the 5.25 inch technology out of the market as the latter could not compete on price. Similarly, digital cameras, when introduced in 1997 performed extremely poorly as compared to traditional film cameras. Consequently, many traditional film companies such as Kodak ignored this market only to be bankrupted by the rise of digital cameras a decade later.Leaders and strategists should be cautious while rejecting a technology that does not seem to be as high performing and hence not as profitable as their dominant technologies. A technology that initially provides low performance can drastically improve over time and often exceed the performance of the dominant technology at a much lower price-point, a scenario that could potentially bankrupt the incumbents who ignored the technology at their peril.Which of the following exemplifies a technological disruption as described in the passage through the 8 inch and 5.25 inch disc drive example?
