# Avoid Double-Barreled Questions

*Each question should focus on just one aspect. Otherwise you don't know what the answer refers to.*

### One aspect per question

Each question should focus on **just one** aspect. Otherwise you don't know what the answer refers to.

### Example

"In your opinion, is Coca-Cola tasty and refreshing?"

### Ask instead

1. "In your opinion, is Coca-Cola tasty?" 2. "In your opinion, is Coca-Cola refreshing?"
