The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
This question asks for a ratio between two values from the "Population per Registered Car" data series, which is represented by the dashed line on the graph.
Step 2: Key Formula or Approach:
1. Read the value from the dashed line for the year 1985. 2. Read the value from the dashed line for the year 1975. 3. Calculate the ratio: (Value in 1985) / (Value in 1975).
Step 3: Detailed Explanation:
- Value in 1985: Locate 1985 on the x-axis. Follow the vertical line up to the dashed line. The data point is slightly below the midpoint between the (inferred) 4 and 6 on the left-side scale. A reasonable estimate is approximately 4.8. - Value in 1975: Locate 1975 on the x-axis. Follow the vertical line up to the dashed line. The data point is about halfway between 6 and 7. A reasonable estimate is approximately 6.5. - Calculate the ratio: \[ \text{Ratio} = \frac{\text{Value in 1985}}{\text{Value in 1975}} \approx \frac{4.8}{6.5} \] To compute this, we can multiply the numerator and denominator by 10 to get \(\frac{48}{65}\). \[ 48 \div 65 \approx 0.738 \] - The calculated value, 0.738, is closest to the answer choice 0.75.
Step 4: Final Answer:
The ratio of the population per car in 1985 (approx. 4.8) to that in 1975 (approx. 6.5) is approximately 0.74, which is most nearly 0.75.

- Should we really care for the greatest actors of the past could we have them before us? Should we find them too different from our accent of thought, of feeling, of speech, in a thousand minute particulars which are of the essence of all three? Dr. Doran's long and interesting records of the triumphs of Garrick, and other less familiar, but in their day hardly less astonishing, players, do not relieve one of the doubt. Garrick himself, as sometimes happens with people who have been the subject of much anecdote and other conversation, here as elsewhere, bears no very distinct figure. One hardly sees the wood for the trees. On the other hand, the account of Betterton, "perhaps the greatest of English actors," is delightfully fresh. That intimate friend of Dryden, Tillatson, Pope, who executed a copy of the actor's portrait by Kneller which is still extant, was worthy of their friendship; his career brings out the best elements in stage life. The stage in these volumes presents itself indeed not merely as a mirror of life, but as an illustration of the utmost intensity of life, in the fortunes and characters of the players. Ups and downs, generosity, dark fates, the most delicate goodness, have nowhere been more prominent than in the private existence of those devoted to the public mimicry of men and women. Contact with the stage, almost throughout its history, presents itself as a kind of touchstone, to bring out the bizarrerie, the theatrical tricks and contrasts, of the actual world.

- “Reviving the practice of using elements of popular music in classical composition, an approach that had been in hibernation in the United States during the 1960s, composer Philip Glass (born 1937) embraced the ethos of popular music in his compositions. Glass based two symphonies on music by rock musicians David Bowie and Brian Eno, but the symphonies' sound is distinctively his. Popular elements do not appear out of place in Glass's classical music, which from its early days has shared certain harmonies and rhythms with rock music. Yet this use of popular elements has not made Glass a composer of popular music. His music is not a version of popular music packaged to attract classical listeners; it is high art for listeners steeped in rock rather than the classics.

- Called by some the “island that time forgot,” Madagascar is home to a vast array of unique, exotic creatures. One such animal is the aye-aye. First described by western science in 1782, it was initially categorized as a member of the order Rodentia. Further research then revealed that it was more closely related to the lemur, a member of the primate order. Since the aye-aye is so different from its fellow primates, however, it was given its own family: Daubentoniidae. The aye-aye has been listed as an endangered species and, as a result, the government of Madagascar has designated an island off the northeastern coast of Madagascar as a protected reserve for aye-ayes and other wildlife.
Long before Western science became enthralled with this nocturnal denizen of Madagascar’s jungles, the aye-aye had its own reputation with the local people. The aye aye is perhaps best known for its large, round eyes and long, extremely thin middle finger. These adaptations are quite sensible, allowing the aye-aye to see well at night and retrieve grubs, which are one of its primary food sources, from deep within hollow branches. However, the aye-aye’s striking appearance may end up causing its extinction. The people of Madagascar believe that the aye-aye is a type of spirit animal, and that its appearance is an omen of death. Whenever one is sighted, it is immediately killed. When combined with the loss of large swaths of jungle habitat, this practice may result in the loss of a superb .- GRE - 2025
