The full passage and all 4 questions (Q17–Q20) from CAT 2024 Slot 2, with answers and solutions.

The passage below is accompanied by four questions. Based on the passage, choose the best answer for each question.

The history of any major technological or industrial advance is inevitably shadowed by a less predictable history of unintended consequences and secondary effects - what economists sometimes call "externalities." Sometimes those consequences are innocuous ones, or even beneficial. Gutenberg invents the printing press, and literacy rates rise, which causes a significant part of the reading public to require spectacles for the first time, which creates a surge of investment in lens-making across Europe, which leads to the invention of the telescope and the microscope.

Oftentimes the secondary effects seem to belong to an entirely different sphere of society. When Willis Carrier hit upon the idea of air-conditioning, the technology was primarily intended for industrial use: ensuring cool, dry air for factories that required low-humidity environments. But...it touched off one of the largest migrations in the history of the United States, enabling the rise of metropolitan areas like Phoenix and Las Vegas that barely existed when Carrier first started tinkering with the idea in the early 1900s.

Sometimes the unintended consequence comes about when consumers use an invention in a surprising way. Edison famously thought his phonograph, which he sometimes called "the talking machine," would primarily be used to take dictation....But then later innovators... discovered a much larger audience willing to pay for musical recordings made on descendants of Edison's original invention. In other cases, the original innovation comes into the world disguised as a plaything...the way the animatronic dolls of the mid-1700s inspired Jacquard to invent the first "programmable" loom and Charles Babbage to invent the first machine that fit the modern definition of a computer, setting the stage for the revolution in programmable technology that would transform the 21st century in countless ways.

We live under the gathering storm of modern history's most momentous unintended consequence....carbon-based climate change. Imagine the vast sweep of inventors whose ideas started the Industrial Revolution, all the entrepreneurs and scientists and hobbyists who had a hand in bringing it about. Line up a thousand of them and ask them all what they had been hoping to do with their work. Not one would say that their intent had been to deposit enough carbon in the atmosphere to create a greenhouse effect that trapped heat at the surface of the planet. And yet here we are.

Ethyl (leaded fuel) and Freon belonged to the same general class of secondary effect innovations whose unintended consequences stem from some kind of waste by-product that they emit. But the potential health threats of Ethyl (unleaded fuel) were visible in the 1920s, unlike, say, the long-term effects of atmospheric carbon build up in the early days of the Industrial Revolution...

Indeed, it is reasonable to see CFCs (chlorofluorocarbons) as a forerunner of the kind of threat we will most likely face in the coming decades, as it becomes increasingly possible for individuals or small groups to create new scientific advances - through chemistry or biotechnology or materials science - setting off unintended consequences that reverberate on a global scale.

Question 17 · RC Inference Questions

We can assume that the author would support all of the following views EXCEPT:
  1. A
    While technological advances in the past have had innocuous or beneficial outcomes, more recent advances have the potential to be more threatening globally.
  2. B
    The by-products of leaded fuel, rather than the fuel itself, were responsible for the build-up of carbon-related gases in the atmosphere.
  3. C
    The emissions caused by the large-scale use of leaded fuel ought to have been addressed earlier than they were.
  4. D
    It has become far easier for people today to bring out innovations with dire worldwide consequences than it was earlier.
Pick an option, then check.
Answer & solution

Answer: Option A

Option 1 says past advances had innocuous or beneficial outcomes while recent ones are more threatening. The author does not hold this view. He gives a harmful past example – carbon-based climate change from the Industrial Revolution, 'modern history's most momentous unintended consequence' – and says past consequences were 'sometimes' innocuous, not always. So he would not support option 1.

Option 2 fits the author's description of Ethyl and Freon as innovations 'whose unintended consequences stem from some kind of waste by-product that they emit'.

Option 3 fits: 'the potential health threats of Ethyl... were visible in the 1920s', implying they could have been addressed sooner.

Option 4 fits the last paragraph: 'it becomes increasingly possible for individuals or small groups to create new scientific advances... setting off unintended consequences that reverberate on a global scale'.

Shortcut: in a 'would support all EXCEPT' question, look for an option that sets up a clean past-versus-present contrast. If the passage itself gives a harmful past example, that contrast is false.

Hence, the answer is option 1.

Question 18 · RC Detail and Fact Based Questions

The author lists all of the following examples as "externalities" of major technical advances EXCEPT:
  1. A
    application of the Jacquard loom to modern IT programming
  2. B
    build-up of chlorofluorocarbons in the atmosphere
  3. C
    extension of the phonograph to large-scale recording of music
  4. D
    cooling and de-humidifying of factories through air-conditioning
Pick an option, then check.
Answer & solution

Answer: Option D

Externalities are 'unintended consequences and secondary effects'.

Option 1 – the Jacquard loom leading to programmable technology – is listed as a secondary effect of animatronic dolls.

Option 2 – the build-up of CFCs – is given as a by-product of Freon, an unintended consequence.

Option 3 – the phonograph being used for music recording – is the unexpected use Edison did not foresee.

Option 4 – cooling and de-humidifying factories – was air-conditioning's intended purpose: 'the technology was primarily intended for industrial use'. The externality was the mass migration to cities like Phoenix and Las Vegas, not factory cooling.

Shortcut: in an externality question, separate each invention's intended use from its side effect. The option that describes the intended use is the exception.

Hence, the answer is option 4.

Question 19 · RC - Questions

Carrier, Babbage, and Edison are mentioned in the passage to illustrate the author's point that
  1. A
    despite the original intention, the unintended consequences of their inventions were largely beneficial.
  2. B
    these inventors could not have visualised the eventual impact of their inventions on society.
  3. C
    the secondary effect of past inventions mostly resulted in the creation of new inventions.
  4. D
    inventions typically end up being used for entirely different purposes than the intended ones.
Pick an option, then check.
Answer & solution

Answer: Option B

The three inventors illustrate unintended consequences: Carrier meant air-conditioning for factories but it set off a mass migration; Edison expected the phonograph to take dictation but it became a music medium; Babbage's machine, inspired by animatronic dolls, set the stage for the programmable-technology revolution. In each case the inventor could not foresee the eventual impact.

Option 2 states that point.

Option 1 says the consequences were 'largely beneficial'. The passage does not judge these three as beneficial; its point is that they were unforeseen.

Option 3 says secondary effects mostly produced new inventions. That fits Babbage, not Carrier's migration or Edison's music market.

Option 4 says inventions 'typically' end up used for entirely different purposes. That overgeneralises; air-conditioning still cooled factories, and the passage claims only that effects reached beyond intent.

Shortcut: when several examples illustrate one point, find what all of them share. 'Could not foresee the impact' fits every case; the other options fit only some.

Hence, the answer is option 2.

Question 20 · RC Main Idea and Central Theme

Which of the following best conveys the main point of the first paragraph?
  1. A
    The full impact of technological advances cannot be estimated in the short run as the ripple effects often extend far beyond the original intent.
  2. B
    The secondary effects of most major technological advances in the past, especially if they were unintended, have turned out to be beneficial.
  3. C
    The entire impact of a technological advance should be evaluated by the boost its secondary effects gives to generating further technological advances.
  4. D
    It is important to judge an invention not by its immediate outcomes, but by the holistic impact of its secondary effects.
Pick an option, then check.
Answer & solution

Answer: Option A

The first paragraph says every major advance 'is inevitably shadowed by a less predictable history of unintended consequences and secondary effects', and gives the Gutenberg chain: printing press, literacy, spectacles, lens-making, telescope and microscope.

Option 1 captures this: the full impact of an advance cannot be judged in the short run because its ripple effects reach far beyond the original intent.

Option 2 says 'most' past secondary effects were beneficial. The paragraph says only that 'sometimes' they are innocuous or beneficial.

Option 3 says an advance should be evaluated by how far it boosts further advances – a prescription the paragraph never makes.

Option 4 tells us how we ought to judge inventions. The paragraph describes what happens; it does not prescribe a method of judging.

Shortcut: for a 'main point' question on a descriptive paragraph, reject options with 'should' or 'it is important to' unless the paragraph itself prescribes something.

Hence, the answer is option 1.
