TOEFL Listening: Bode's Law


1 What is Bode's law about? 

  1. A different interpretation of Newton’s gravitation

  2. Measurement of the distance between  the sun and the earth

  3. Distance of planets from the sun

  4. Prediction of how many planets there are

2. Why does the professor explain Bode's Law to the class? 

  1. To explain some patterns in numbers

  2. To explain how the asteroids belt was discovered 

  3. To explain how gravitational forces influence the planets

  4. To explain how telescope helped finding Uranus

3. How does the professor introduce Bode's Law? 

  1. By demonstrating how it is derived mathematically

  2. By describing the discovery of Uranus

  3. By drawing attention to the inaccuracy of a certain pattern

  4. By telling the names of several of the asteroids

4. According to the professor, what two factors contributed to the discovery of the asteroid Ceres? Click on 2 answers 

  1. Improved telescopes

  2. Advances in mathematics

  3. The discovery of a new star based on Bode’s law

  4. The discovery of Uranus based on Bode’s law

5. What does the professor imply about the asteroid belt? 

  1. It is farther from the Sun than Uranus

  2. Bode believed it was made up of small stars

  3. It is located where people expected to find a planet

  4. Ceres is the only one of the asteroids that can be seen without a telescope

6. Why does the professor say “This pattern is known as Bode’s Law. Um, it isn’t really a scientific law, not in the sense of predicting gravitation mathematically or something,” 

  1. To introduce an alternative application of Bode's Law

  2. To give an example of what Bode's law cannot explain

  3.  To describe the limitations of gravitational theory

  4.  To contrast Bode's Law with a real scientific law

7. What can we infer from “But I kind of have to skip the one after Mars for now.”

  1. He will explain how the spot was filled later

  2. No planet has been found in that spot so far

  3. The professor feels that the correspondence between Bode’s numbers and the placements of planets too obvious

  4. The professor feels that Bode’s law doesn’t work after all since no planets exist in that spot

8. How was Ceres discovered? 

  1. it was discovered by accident when people started to look at the night sky with telescopes

  2. It was discovered immediately after Bode proposed his law 

  3. People searched for it at a specific spot

  4. It was discovered when people looked for Uranus.

9. Based on the lecture, which one of these can we infer was available to astronomers around the time when Bode proposed his law?

  1. knew about the existence of Uranus

  2. knew Ceres was an asteroid

  3. knew how to measure the distance of the sun from the earth

  4. knew how to use telescopes to discover Jupiter and Saturn

10. Arrange the events mentioned in the lecture in the chronological order

  1. Asteroid Belt was discovered

  2. Uranus was discovered

  3. Bode discovered a pattern in planets’ distances
