Expression of Ideas practice question
While researching a topic, a student has taken the following notes:
- In 1970 the average new car in the country weighed 1,100 kilograms.
- In 2020 it weighed 1,600 kilograms.
- Safety equipment and larger body styles account for most of the increase.
- Heavier cars use more fuel for the same distance.
The student wants to emphasise how much the average new car's weight changed. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- A. The average new car gained 500 kilograms between 1970 and 2020, rising from 1,100 to 1,600 kilograms.Correct
- B. Heavier cars use more fuel.
- C. In 2020 the average new car weighed 1,600 kilograms.
- D. Safety equipment adds weight to cars.
Answer: A. The average new car gained 500 kilograms between 1970 and 2020, rising from 1,100 to 1,600 kilograms.
Both weights, both years, and the size of the gain.
Why the other answers are wrong
- B. Heavier cars use more fuel.
- A consequence of weight, not the change in it.
- C. In 2020 the average new car weighed 1,600 kilograms.
- One figure can't show a change.
- D. Safety equipment adds weight to cars.
- A cause of the change, not its size.
