Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - City A's bike-share scheme has 5,000 bikes and records about 2 million rides a year. - City B's scheme has 1,000 bikes and records about 900,000 rides a year. - Both schemes charge the same fares. - Both cities have similar climates. The student wants to show that City B's bikes are used more intensively than City A's.

Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. Although City A has five times as many bikes, each of City B's bikes makes about 900 rides a year against about 400 for City A's, so City B's fleet is used far more intensively.Correct
  2. B. City A records about 2 million rides a year, more than twice City B's total.
  3. C. Both schemes charge the same fares.
  4. D. City B has 1,000 bikes.

Answer: A. Although City A has five times as many bikes, each of City B's bikes makes about 900 rides a year against about 400 for City A's, so City B's fleet is used far more intensively.

Rides per bike, which is the measure of intensity.

Why the other answers are wrong

B. City A records about 2 million rides a year, more than twice City B's total.
Total rides favour City A and do not measure intensity.
C. Both schemes charge the same fares.
Irrelevant to intensity.
D. City B has 1,000 bikes.
A count alone.
