Question

cities have explored a myriad of ways to improve public transportation by making it more ____. one strategy for doing so that has seen widespread adoption is contactless payment systems for buses: when riders can pay for their trip with a simple tapping motion on board, drivers can spend less time paused at each stop before continuing their routes.
which choice completes the text with the most logical and precise word or phrase?
a efficient
b affordable
c relatable
d cumbersome

Explanation:

To solve this, we analyze the context: cities are improving public transportation, and the strategy (contactless payment) helps drivers spend less time at stops. We need a word that describes an improvement in transportation flow.

• "Efficient" means achieving maximum productivity with minimum wasted effort/time. This fits as the contactless payment reduces stop time, making transportation more efficient.
• "Affordable" relates to cost, not time/efficiency here.
• "Relatable" means easy to relate to, irrelevant to transportation improvement.
• "Cumbersome" means complicated, the opposite of what the strategy achieves.

Answer:

A. efficient
