Expression of Ideas practice question
While researching a topic, a student has taken the following notes:
- Venus is the second planet from the Sun.
- Its diameter is about 95% of Earth's.
- Its mass is about 82% of Earth's.
- Its surface temperature averages about 465°C.
- A day on Venus lasts longer than its year.
The student wants to emphasise how similar Venus and Earth are in size. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- A. Venus is nearly Earth's twin in size, with about 95% of Earth's diameter and 82% of its mass.Correct
- B. Venus's surface temperature averages about 465°C.
- C. A day on Venus lasts longer than its year.
- D. Venus is considerably smaller than Earth in both diameter and mass.
Answer: A. Venus is nearly Earth's twin in size, with about 95% of Earth's diameter and 82% of its mass.
Only choice A uses the two size figures and frames them as near-equality.
Why the other answers are wrong
- B. Venus's surface temperature averages about 465°C.
- Temperature says nothing about size.
- C. A day on Venus lasts longer than its year.
- Day length says nothing about size.
- D. Venus is considerably smaller than Earth in both diameter and mass.
- 'Considerably smaller' contradicts 95% and 82%.
