This achievement can only be earned in games where there is a timer.
Start a game from the main menu by clicking "Play" > "Solo" > "Normal" > "Next". Then select your character and begin. The first five questions should be very easy and are the best questions to get this on.
Read the questions and highlight your answer but don't click "A" until the timer hits "0". Keep an eye on the timer gauge to ensure that you hit "A" when the timer is on "0" but the gauge hasn't fully depleted. Answering when the timer is on anything other than "0" will not count for the achievement.
After answering the first five questions, you can either carry on with the next five for the achievement or restart the game for the easier questions. Either way, simply answer ten questions when the timer is on "0" to get this achievement.
