Craft and Structure practice question

Praise for the city's new bike-share scheme is premature. Ridership has indeed doubled since the launch — but the launch was in February. The doubling reflects the arrival of spring weather, not the scheme's design. A fair test will come when this winter's numbers are set against last winter's.

What is the main purpose of the text?

  1. A. To argue that a claimed success has not yet been properly measured.Correct
  2. B. To criticise the design of the bike-share scheme.
  3. C. To explain why people cycle more in warm weather.
  4. D. To predict that ridership will fall once winter arrives.

Answer: A. To argue that a claimed success has not yet been properly measured.

The text accepts the doubling but argues it doesn't show what its admirers think, and says what a real test would be. Its purpose is to question the measurement, not the scheme.

Why the other answers are wrong

B. To criticise the design of the bike-share scheme.
The author says nothing against the scheme's design — only that the numbers don't yet prove anything about it.
C. To explain why people cycle more in warm weather.
Spring weather is offered as an alternative explanation, not explained in itself.
D. To predict that ridership will fall once winter arrives.
The author calls for a winter comparison; no prediction about the result is made.
