On a recent expedition to a remote region of northern Canada, scientists uncovered skeletal remains from about 100,000 years ago. Surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees Fahrenheit (or 538 degrees Celsius).
Q. Which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures?
  • a)
    Other scientific research released two years before the expedition showed that the remote region of northern Canada underwent considerable warming in the past 100,000 years.
  • b)
    Chemical changes that naturally occur during the process of decay in only one north Canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found.
  • c)
    A little over 103,000 years ago, a large fire is known to have occurred in northern Canada.
  • d)
    Strong evidence exists that as early as 70,000 years ago, Homo sapiens around the world relied heavily on fire to cook animals.
  • e)
        In the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
Correct answer is option 'E'. Can you explain this answer?

The paradox: Northern Canada is quite cold and yet skeletal remains show evidence of experiencing very hot temperatures. This paradox could be explained by finding evidence that fires regularly occurred that would have subjected the bones to excruciatingly hot temperatures. If evidence existed that early humans from this time period hunted animals and started fires (implicitly for the purpose of cooking the animals--thereby creating skeletons of animals that experienced hot temperatures), a large step in explaining the paradox would be taken.
A. Unraveling the paradox depends on providing an explanation of how the skeletal remains experienced such hot temperatures yet this answer only heightens the paradox as it provides evidence that the skeletons' environment was much colder (not warmer) many years ago.
B. Although this provides an explanation of how "exactly one north Canadian species'" skeletons showed evidence of exposure to hot temperatures, it fails to account for why "many species from differing biological families [that] spanned about two thousand years showed" the same evidence of exposure to hot temperatures.
C. This answer provides an explanation for skeletons showing evidence of experiencing hot temperatures. However, this answer does not explain why this evidence appeared among skeletons whose date "spanned about two thousand years." Further, the fire occurred "a little over 103,000 years ago" while the original argument makes clear that some of the skeletons which showed evidence of experiencing hot temperatures dated after this fire (i.e., the skeletons were from 100,000 years ago and "spanned about two thousand years" while the fire occurred "over 103,000 years ago").
D. The paradox exists in skeletons dating back to 100,000 years ago. Consequently, explaining how a fire (and thus hot temperatures) could have existed "as early as 70,000 years ago" does not explain the paradox. In other words, this answer does not explain how the skeletons of animals 100,000 years old experienced hot temperatures (although it would explain how skeletons 70,000 years old experienced hot temperatures).
E. While this answer does not prove what caused the chared skeletal remains, it "best explains" how the skeletons experienced hot temperatures (i.e., the hunters cut wood and, implied in this, they started fires to cook animals).

Explanation:

Evidence of Early Human Activity:
- The discovery of rudimentary wood cutting and hunting tools used by early humans in the same layer of excavation as the skeletal remains suggests human presence in the region.
- This finding supports the idea that early humans were responsible for the exposure of the bones to high temperatures.

Use of Fire by Early Humans:
- Early humans were known to rely heavily on fire as early as 70,000 years ago for various purposes, including cooking animals and providing warmth.
- The evidence of hot temperatures on the skeletal remains aligns with the known behavior of early humans using fire.

Connection between Human Activity and Bone Temperature:
- The presence of tools used by early humans alongside the skeletal remains indicates a direct link between human activity and the high temperatures experienced by the bones.
- It is likely that early humans in the region used fire for cooking, warmth, or other purposes, leading to the heat exposure seen in the bones.

Therefore, option E, which suggests the coexistence of early human activity and the evidence of hot temperatures on the bones, best explains the paradox between the cold environment of northern Canada and the findings of the expedition.

Similar GMAT Doubts

Climatic conditions are delicately adjusted to the composition of the Earth’s atmosphere. If there were a change in the atmosphere—for example, in the relative proportions of atmospheric gases—the climate would probably change also. A slight increase in water vapor, for instance, would increase the heat-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the amount of solar energy reaching the Earth’s surface.The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth’s incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation, which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2 concentration would lead only to a reduction in global temperatures of 3.If, because of an increase in forest fires or volcanic activity, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2 would probably increase. As a consequence, plants would use more and more CO2. Eventually CO2 levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increases and decreases of a set magnitude.Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature increase of at least 1. But a supposed global temperature rise of 1 may in reality be only several regional temperature increases, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example the Southern Hemisphere oceanic zone, may be experiencing an equivalent temperature decrease that is unrecognized because of the shortage of meteorological recording stations.The passage supplies information for answering which of the following questions?
