A passenger can help the driver to drive safely by
- avoiding heated or emotional conversations ✓
- talking loudly so he or she can hear the conversation
- asking questions about the route to keep the driver alert
- turning up the radio
Answer: A. avoiding heated or emotional conversations
A passenger can help the driver by avoiding heated or emotional conversations.
Why this is the answer
The handbook's good-passenger advice says you can help a driver by avoiding heated or emotional conversations because these can distract the driver. That matches the choice about avoiding heated or emotional conversations. The other choices add conversation or noise; the passage does not present those as ways to help and instead focuses on reducing distraction. So the passenger's useful action is to keep talk calm and avoid emotional exchanges.
Why the other answers are wrong
- B. talking loudly so he or she can hear the conversation — The handbook does not list talking loudly as helpful, and extra noise is not part of its good-passenger advice.
- C. asking questions about the route to keep the driver alert — The passage does not recommend asking route questions to keep the driver alert; it names avoiding heated or emotional conversations instead.
- D. turning up the radio — Turning up the radio is not listed as a way to help, and added noise is not part of the handbook's good-passenger advice.
Remember it
If the talk starts heating up, let it cool: calm conversation helps the driver.
