The best reason that we know more about the K-T extinction event (the one that eliminated the dinosaurs) than other extinction events is because

A.
evidence for previous events is buried too far beneath the earth.
B.
dinosaurs are popular which leads to more research funds for excavations.
C.
the search for new sources for oil leads to new fossil finds.
D.
A, B and C are all correct.
E.
None of these is correct.

E. None of these is correct.

E. None of these is correct.

The best reason that we know more about the K-T extinction event than other extinction events is because of extensive scientific research and analysis of the geologic record. This event, which occurred 65 million years ago, is one of the most well-studied and well-documented extinction events due to the abundance of evidence that has been preserved in the rock layers. The discovery of a distinct geological boundary layer containing high levels of iridium, a rare element in Earth's crust but abundant in extraterrestrial objects like asteroids, helped solidify the connection between the extinction event and the impact of a large asteroid or comet.

The correct answer to the question is B. Dinosaurs are popular which leads to more research funds for excavations. This is the best reason why we know more about the K-T extinction event compared to other extinction events. However, let me explain each of the options to give you a better understanding:

A. Evidence for previous events is buried too far beneath the earth: This option suggests that evidence for other extinction events is buried too deep to be accessible or studied. While it is true that some evidence may be buried deep underground, scientists have developed techniques such as drilling cores and seismic imaging to study these deeper layers. So, while it may pose some challenges, it is not the best reason why we know more about the K-T extinction event.

B. Dinosaurs are popular which leads to more research funds for excavations: This option suggests that the popularity of dinosaurs generates more interest and support for research and excavations related to them. Since dinosaurs are widely known and capture public imagination, there is more funding available for scientists to study and understand the K-T extinction event. This funding allows for more thorough research and better preservation of fossil evidence.

C. The search for new sources for oil leads to new fossil finds: This option suggests that while searching for new sources of oil, fossil discoveries are made. While this can be true to some extent, it is not the primary reason why we know more about the K-T extinction event. Fossil discoveries during oil exploration can happen sporadically and are often not extensive enough to provide a comprehensive understanding of other extinction events.

D. A, B, and C are all correct: This option suggests that all the previous options are correct. However, as explained above, the main reason why we know more about the K-T extinction event is the popularity of dinosaurs, leading to more research funds for excavations. The other options are not as significant in comparison.

E. None of these is correct: This option suggests that none of the statements mentioned are valid reasons for knowing more about the K-T extinction event. However, the popularity and fascination with dinosaurs, resulting in increased research funds, are widely recognized as major driving factors in our understanding of the K-T extinction event.

So, the best reason is B. Dinosaurs are popular which leads to more research funds for excavations.
