Question based on the following passage.
The Secret Life of Photons

Anyone who has gazed into the deep darkness of space on a clear, moonless night can understand why stars have always fascinated us. Ancient cultures believed that stars (1) sufficed as omens of earthly events, and even influenced individual lives through their “interactions” with the planets. To the more science-minded, they (2) have beckoned for us long with the physical mysteries behind their colossal beauty.
(3) Although we now know that the stars beyond our sun are far too distant to exert any significant influence on planetary motion, let alone human affairs, it seems that modern astronomers are nevertheless exercising mystical powers of divination. Today's astronomers claim to know the distance, age, speed, and even chemical composition of objects that are so distant we (4) might hope never to send probes there. (5) How can they claim to know so much about stars that are often millions of light years away?
It's really an incredible feat. Consider the remarkable fact that all the information we have about stars is indirect. Unlike other objects of fascination—like microbes, the ocean floor, or even the moon—(6) we can't easily sample stars to observe them under a microscope. Instead, we must depend on the photons they emit, tiny packets of energy that must often travel thousands of billions of billions of miles or (7) more. At that point, the photons are finally absorbed by a digital camera or the retina of an eyeball that is peering through a telescope. Additionally, we can infer information about a star by looking in its neighborhood. Changes in the behavior of nearby bodies such as other stars or clouds of gas often indicate the presence of a star, (8) even when that star is too dim to see.
The light from the most distant observable (9) stars, began their journey more than 50 million years ago. In that time, the steady expansion of space itself stretched the wavelength of each photon, in a process called “redshifting.” The (10) experience of this redshifting tells astronomers how far the photon had to travel, and hence how far away the star is (or was).
The photons from a single star are not all the same wavelength, however, and that's a good thing.
The wavelengths fall into a wide (11) spectrum, which characteristics reveal the size of the star as well as the presence of elements such as hydrogen, helium, calcium, sodium, and even titanium.
Q. (10)
  • a)
    no change
  • b)
    exposure
  • c)
    extent
  • d)
    expedience
Correct answer is option 'C'. Can you explain this answer?
Most Upvoted Answer
Directions: Each passage below is accompanied by a number of questions...
The point of this sentence is that the amount of the red-shift in the light indicates how far the light has traveled. In other words, the extent of this redshifting tells astronomers how far away the star is (or was).

Choose that option if you think the best choice is to leave the relevant portion of the passage as it is.Question based on the following passage.The Secret Life of PhotonsAnyone who has gazed into the deep darkness of space on a clear, moonless night can understand why stars have always fascinated us. Ancient cultures believed that stars (1) sufficed as omens of earthly events, and even influenced individual lives through their “interactions” with the planets. To the more science-minded, they (2) have beckoned for us long with the physical mysteries behind their colossal beauty.(3) Although we now know that the stars beyond our sun are far too distant to exert any significant influence on planetary motion, let alone human affairs, it seems that modern astronomers are nevertheless exercising mystical powers of divination. Todays astronomers claim to know the distance, age, speed,and even chemical composition of objects that are so distant we (4) might hope never to send probes there. (5) How can they claim to know so much about stars that are often millions of light years away?Its really an incredible feat. Consider the remarkable fact that all the information we have about stars is indirect. Unlike other objects of fascination—like microbes, the ocean floor, or even the moon—(6) we cant easily sample stars to observe them under a microscope. Instead, we must depend on the photons they emit, tiny packets of energy that must often travel thousands of billions of billions of miles or (7) more. At that point, the photons are finally absorbed by a digital camera or the retina of an eyeball that is peering through a telescope. Additionally, wecan infer information about a star by looking in its neighborhood. Changes in the behavior of nearby bodies such as other stars or clouds of gas often indicate the presence of a star, (8) even when that star is too dim to see.The light from the most distant observable (9) stars, began their journey more than 50 million years ago. In that time, the steady expansion of space itself stretched the wavelength of each photon, in a process called “redshifting.” The (10) experience of this redshifting tells astronomers how far the photon had to travel, and hence how far away the star is (or was).The photons from a single star are not all the same wavelength, however, and thats a good thing.The wavelengths fall into a wide (11) spectrum, which characteristics reveal the size of the star as well as the presence of elements such as hydrogen, helium, calcium, sodium, and even titanium.Q.
