who can control traffic at a drawbridge so that stopping is not required when it opens?
a drawbridge attendant or traffic officer
a railroad crossing signal operator
a pedestrian crossing guard

Explanation:

To determine who controls traffic at a drawbridge so stopping is not required when it opens, we analyze the options:

• A pedestrian crossing guard is for pedestrian crossings, not drawbridges.
• A railroad crossing signal operator deals with railroad crossings, not drawbridges.
• A drawbridge attendant or traffic officer is responsible for controlling traffic at a drawbridge, ensuring smooth passage when it opens without the need for stopping (in the context of drawbridge operations).

Answer:

A. A drawbridge attendant or traffic officer
