CAT 2025 Question Paper | VARC Slot 2

The only way to master VARC during your CAT Preparation is by practicing actual CAT question paper. Practice RCs with detailed video and text solutions from Previous CAT Question Papers.

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

Different sciences exhibit different science cultures and practices. For example, in astronomy, observation – until what is today called the new astronomy – had always been limited to what could be seen within the limits of optical light. Indeed, until early modernity the limits to optical light were also limits of what humans could themselves see within their limited and relative perceptual spectrum of human vision. With early modernity and the invention of lensed optical instruments – telescopes – astronomers could begin to observe phenomena never seen before. Magnification and resolution began to allow what was previously imperceptible to be perceived – but within the familiar limits of optical vision. Galileo, having learned of the Dutch invention of a telescope by Hans Lippershey, went on to build some hundred of his own, improving from the Dutch 3x to nearly 30x telescopes – which turn out to be the limit of magnificational power without chromatic distortion. And it was with his own telescopes that he made the observations launching early modern astronomy (phases of Venus, satellites of Jupiter, etc.). Isaac Newton’s later improvement with reflecting telescopes expanded upon the magnificational-resolution capacity of optical observation; and, from Newton to the twentieth century, improvement continued on to the later very large array of light telescopes today – following the usual technological trajectory of “more-is-better” but still remaining within the limits of the light spectrum. Today’s astronomy has now had the benefit of some four centuries of optical telescopy. The “new astronomy,” however, opens the full known electromagnetic spectrum to observation, beginning with the accidental discovery of radio astronomy early in the twentieth century, and leading today to the diverse variety of EMS telescopes which can explore the range from gamma to radio waves. Thus, astronomy, now outfitted with new instruments, “smart” adaptive optics, very large arrays, etc., illustrates one style of instrumentally embodied science – a technoscience. Of course astronomy, with the very recent exceptions of probes to solar system bodies (Moon, Mars, Venus, asteroids), remains largely a “receptive” science, dependent upon instrumentation which can detect and receive emissions.

Contemporary biology displays a quite different instrument array and, according to Evelyn Fox-Keller, also a different scientific culture. She cites her own experience, coming from mathematical physics into microbiology, and takes account of the distinctive instrumental culture in her Making Sense of Life (2002). Here, particularly with the development of biotechnology, instrumentation is far more interventional than in the astronomy case. Microscopic instrumentation can be and often is interventional in style: “gene-splicing” and other techniques of biotechnology, while still in their infancy, are clearly part of the interventional trajectory of biological instrumentation. Yet, in both disciplines, the sciences involved are today highly instrumentalized and could not progress successfully without constant improvements upon the respective instrumental trajectories. So, minimalistically, one may conclude that the sciences are technologically, instrumentally embodied. But the styles of embodiment differ, and perhaps the last of the scientific disciplines to move into such technical embodiment is mathematics, which only contemporarily has come to rely more and more upon the computational machinery now in common use.

Question 21 : All of the following statements may be rejected as valid inferences from the passage EXCEPT:

Explanatory Answer

The question asks which of the given options is a valid inference from the passage.
Option 1 is incorrect. The 'new astronomy' telescopes are those that open the full known electromagnetic spectrum to observation. Newton did not develop one of these.
Option 2 is also not a valid inference. Refer to the last paragraph. The passage says interventionist instruments used in microbiology are, like the instruments used in astronomy, also embodied. It is just the styles of embodiment that differ.
Now consider option 3. The passage says that astronomy is a 'receptive' science dependent upon instrumentation which can detect and receive emissions. It contrasts this to the scientific culture in microbiology where instrumentation is interventional in style. Option 3 is true, based on the contents of the passage.
Option 4 is incorrect. The passage says it was Galileo who observed the phases of Venus and the satellites of Jupiter with his telescopes.
Option 3 is the correct choice.

The question is " All of the following statements may be rejected as valid inferences from the passage EXCEPT: "

Hence, the answer is 'the author distinguishes between the receptive and interventionist uses of instruments in the sciences by comparing astronomy and biology, respectively.'

Choice 3 is the correct answer.
