Read this excerpt from Chapter 1 of Wheels of Change by Sue Macy. Solid rubber tires and pedals replaced metal ones. Frames were made of steel instead of iron or wood. Seat springs were improved and brakes were added. The weight was reduced to 50 and then 40 pounds. Each of these changes distanced the velocipede from its origins as a machine for the "swift of foot" until finally, a new term became popular for the two-wheeled wonder: bicycle. Which of these were solutions that improved the velocipede? Choose three correct answers.
Answer
A
enhancing the construction of seats
B
adding brakes
C
strengthening wooden frames
D
adding iron for weight
E
eliminating metal tires
Explanation
The excerpt says the seat springs were improved, brakes were added, and solid rubber tires replaced metal tires. These changes correspond to enhancing the construction of seats, adding brakes, and eliminating metal tires. Adding iron or strengthening wooden frames would not help: the velocipede’s frames changed to steel instead of iron or wood.
